Installation ManualQuidway AR 28 Series RoutersChapter 1 OverviewChapter 1 Overview1.1 Brief IntroductionQuidway AR 28 Series Routers are intended for use on enterprise-level networks,including seven models: AR 28-09, 28-10, 28-11, 28-30, 28-31, 28-40, and 28-80.Depending on the network size, Quidway AR 28 Series Routers can either be corerouters on medium-and-small-sized enterprise networks, or access routers for networkbranches on some large-sized enterprise networks. Quidway AR 28 Series Routersadopt modular design and provide multiple MIMs (Multifunctional Interface Modules)and SICs (Smart Interface Cards). In addition, except for AR 28-09, they provide twohost types: AC-powered and DC-powered. Therefore, Quidway AR 28 Series Routersare suitable for the application on the carrier-level networks, such as telecommanagement networks and billing networks.Quidway AR 28 Series Routers adopt high speed PowerPC microprocessor and theVRP (Versatile Routing Platform), a network operation system platform developed byHuawei Technologies. Besides the benefit of simple configuration, VRP provides richnetwork security features, and supports terminal access, SNA (Systems NetworkArchitecture)/DLSw (Data-Link Switching), IP multicast, ATM, MPLS and abundantQoS (Quality of Service) features. Thereby, Quidway AR 28 Series Routers canoperate together with other Quidway series routers and Ethernet switches to provideoverall end-to-end network solutions for medium-and-large-sized enterprises.Quidway AR 28 Series Routers provide the following features:I. High-performance processorQuidway AR 28 Series Routers use high-performance processors to process all theintegrated interface data integrated. All the performance indices, such as packetprocessing capacity, maximum traffic on interfaces, delay, frame drop rate, restorationperiod due to overloading of the system and system reset period, can meet users’requirements.II. Multiple interface card/interface module optionsQuidway AR 28 Series provides SIC slots (only AR 28-09/28-10/28-11 provides SICslots) and MIM slot, where you can install various types of SICs and MIMs. Theavailable interfaces include synchronous/asynchronous serial interface, asynchronousserial interface, AM interface,T1/cT1/PRI interface, E1/cE1/PRI interface, E3/T3interface, BRI S/T and U interfaces,, 10/100/1000 Mbps Ethernet interface (including1-1

Installation ManualQuidway AR 28 Series RoutersChapter 1 Overviewcircuit interface and fiber interface), ADSL interface, ATM interface, and so on. Theuser can change or extend SICs or MIMs as needed. Thereby, the investment that hasbeen made can be protected to the maximum degree.III. Supporting multiple channels of asynchronous serial interface access• Connected to PSTN (Public Switched Telephone Network) via the asynchronousserial interface, the router can work as a small Internet access server.• With an analog Modem interface card (options: SIC-1AM/2AM and 6AM/12AM),the router can be directly connected to PSTN to serve as a small access server.IV. Support ADSL/ATM/MPLS featuresADSL is a simple but highly-efficient broadband technology that achieves the maximumdata transmission capacity over existing copper wiring by using the digital codemodulation technology. The ADSL module for AR 28 Series allows themedium-to-small-sized enterprises to reach the DSLAM equipment via PSTN and thenaccess the Internet.ATM transmits, multiplexes, and switches information in cells. AR 28 Series Routersprovide 155 Mbps ATM module, support AAL5, and offer traffic services like CBR, VBRand UBR. Hence, such routers are well-suited to the high-speed data service,transmission of large packets, and interconnection between midsize or small enterprisenetworks and ATM networks.MPLS, a combination of IP and ATM technologies, replaces the traffic identified by IPheader with a short and length-fixed label, based on which a router makes theforwarding decision. It can provide faster forwarding speed, get support from IP routedprotocols, and control protocols, thus satisfying the requirements that various newapplications put on the network. MPLS VPN is a VPN technology that implements theinterconnection of private networks via Label Switched Paths (LSPs). As LSP is atunnel across the public network on its own, MPLS has an inherent advantage in termsof VPN implementation. AR 28 series Routers usually act as Label Edge Routers(LERs) to implement service classification, label distribution, encapsulation, andmulti-label peel-off by connecting an MPLS domain to a non-MPLS domain orconnecting MPLS domains of different service providers.V. Providing Ethernet access solutionBy extending SICs and MIMs, Quidway AR 28 Series Routers can provide multipleforms of Ethernet interfaces, such as fiber interface/circuit interface, 10/100/1000Mbpsinterface. Thereby, the networking capability of the router can be significantlyimproved.1-2

Installation ManualQuidway AR 28 Series RoutersChapter 1 OverviewVI. Data security• Supports ID authentication protocols, including PAP (Password AuthenticationProtocol), CHAP (Challenge Handshake Authentication Protocol), data RADIUS(Remote Authentication Dial in User Service).• Implements firewall to prevent invasions from external networks.• Supports VPN (Virtual Private Network, including GRE, L2TP, Huawei dynamicVPN and MPLS L2/L3 VPN) and provides IPSec (IP Security) and IKE (InternetKey Exchange) technologies. Hence, the security of the user private network inthe Internet environment can be guaranteed.• Provides backup solutions based on the backup center technology.VII. Online upgrading the software version512 KB Boot ROM and 32 MB Flash memory provide the user with adequate physicalcarrier to upgrade the software online, add new features, and extend new functionsaccording to market demands.VIII. ChassisQuidway AR 28 Series Router adopts integrated structure design. It performsexcellently on heat dissipation, EMC (Electromagnetic Compatibility) and safety.1.2 SLOTThe following table shows the numbers of interfaces and slots on Quidway AR 28Series Routers of different models:Table 1-1 Numbers of interfaces and slots provided by AR 28 Series Routers of different modelsItemAR28-09AR28-10AR28-11AR28-30AR28-31AR28-40AR28-80AUX port 1 1 1 1 1 1 1Console port 1 1 1 1 1 1 1Fixed WAN port 1 1 1 - - - -Fixed LAN port 1 1 2 1 2 - -Extended SIC 2 2 2 - - - -Extended MIM 1 1 1 3 3 4 8 Note:“-” means that this type of routers does not provide the port.1-3

Installation ManualQuidway AR 28 Series RoutersChapter 3 Installation PreparationChapter 3 Installation Preparation3.1 Requirements on EnvironmentAR 28 Series must be used indoors. To ensure the normal operation and prolong theirservice life, the following requirements for installation site must be met.3.1.1 Requirements on Temperature/HumidityCertain requirements on temperature and humidity in the equipment room shall be met.If the relative humidity is too high, the insulation materials in it will deteriorate easily oreven lead to electric leakage. Sometimes this will result in change to the mechanicalperformance of the materials and rusting of the metal components. If the relativehumidity is too low, the fastening screw will become loosen due to shrinkage of theisolation spacer. In an environment with dry climate, static electricity may be produced,putting the CMOS of the router to risk. High temperature is of the greatest risk: for it willsignificantly degrade the router’s reliability, speed up aging process of the insulatingmaterials, and shorten the service life of the router. The requirements on thetemperature and humidity for AR 28 Series are shown in Table 3-1:Table 3-1 Humidity requirements in the equipment roomTemperatureRelative humidity0oC to 40oC 10% to 90%3.1.2 Requirements on CleannessDust is harmful to the safe operation of the Router. Dust on the chassis may result instatic absorption, thus causing poor contact of the metal connection components orpoints. Especially under the condition of low indoor humidity, dust is easier to beabsorbed, which not only shortens the operational lifetime of the equipment, but alsoresults in communication failure.There should not be explosive, conductive, magnetic and corrosive dust in theequipment room where Quidway AR 28 Series Routers are located, and the dustconcentration should meet the following requirements:3-1

Installation ManualQuidway AR 28 Series RoutersChapter 3 Installation PreparationTable 3-2 Limitation on dust content in equipment roomMechanical active material Unit ContentDust particleNote: Dust particle Diameter ≥ 5µmparticle/m³≤3 x 104(No visible dust on desk in three days)Besides the dust specifications, the equipment room of the Router should also meet therigorous requirements for the content of salt, acid and sulfide. These harmful gasescould accelerate the metal erosion and aging process of some parts. The specific limitsof these harmful gases are given in the following table.Table 3-3 Harmful gas limits in an equipment roomGasMax. (mg/m3)SO2 0.2H2S 0.006NH3 0.05Cl2 0.013.1.3 Requirements on Electrostatic Discharge PreventionAlthough many antistatic considerations have been given to AR 28 Series, damage tothe router’s circuit or even the whole equipment may still happen when the staticelectricity exceeds the tolerance threshold.In the communication network to which the routers are connected, static inductionmainly comes from:• External electric fields such as outdoor high voltage power line or thunder.• Internal environment like flooring materials or the whole equipment structure.Thus, the following should be considered to safeguard the equipment against the ESD:• Make sure that the equipment and the floor are well grounded.• Make sure that dust-proof measures are taken.• Maintain an appropriate humidity and temperature.• Wear an ESD-preventive wrist strap and uniform when contacting the circuitboard.• Place the uninstalled circuit board on the antistatic workbench, with its faceupward, or put it into the static shielding bag.3-2

Installation ManualQuidway AR 28 Series RoutersChapter 3 Installation Preparation• When observing or removing the uninstalled circuit board, please touch the edgeof the circuit board, and avoid contacting the devices on it.3.1.4 Requirements on Electromagnetic EnvironmentThe interference sources, no matter where they come from, affect the routers withcapacitance coupling, inductance coupling, radiation of electromagnetic wave,common impedance (including the grounding system) or conducting line (power line,signal line and transmission line etc.).So the following should be considered:• Take effective measures to prevent the power system from being interfered withby the power grid system.• Keep the router far away from the radio launcher, radar launcher, andhigh-frequency devices working in high currents.• Use electromagnetic shielding when necessary.3.1.5 Requirements on Preventing LightningAlthough many measures have been taken to protect AR 28-30/28-31/28-40/28-80Series from lightning, if the lightning intensity exceeds a certain range, damage to therouter may still happen. To protect the router from lightning better, the following shouldbe considered:• Ensure the PGND wire of the chassis is well grounded.• Ensure the ground point of the socket of AC power supply is well grounded.• To enhance the lightning protection capability of the power supply, a lightningarrester could be installed at the input end of the power supply.• As for the signal line outdoors to which the interface modules of AR 28 Seriesrouters are connected, such as ISDN line, telephone line, E1/T1 line, etc, a speciallightning arrester should be installed at the input end of the signal line to enhancethe lightning protection capability.3.1.6 Requirements on WorkbenchNo matter whether you are to install the router in the cabinet or directly place it on theworkbench, it is necessary to ensure that:• There is spacing reserved at the air inlet and outlet in the router so as to facilitatethe radiation of the router cabinet.• The cabinet and workbench have good radiation systems.• The cabinet and workbench are firm enough to support the router and otherinstallation accessories.• The cabinet and workbench are well grounded.3-3

Installation ManualQuidway AR 28 Series RoutersChapter 4 Installation of the Router4.2.3 Installing the Router on a WorkbenchIn many circumstances, you may not own a 19-inch standard rack. Usually, the routerwill be installed on a clean workbench. The operations are very simple, but still, youshould be aware of the following items:• Ensure the stability and well-grounding of the workbench.• Leave a space of 10cm around the router for heat dissipation.• Do not place heavy objects on the router.4.3 Connecting the PGND WireWarning:The normal connection of the PGND wire is an important guard against the lightning and interference.Therefore, the user must first correctly connect the PGND wire before installing and using the device.The power input end of Quidway AR 28 Series Router is connected to a noise filter. Theneutral point of the noise filter is directly connected to the chassis and is calledprotection ground (PGND). The PGND wire must be well grounded, so as to safelyconduct the faradism and leaky electricity to the earth ground, and thereby improve thecapability of the whole device to guard against the electromagnetic interference. ThisPGND wire can also protect the router against the lightning caused by the connectionwith the external network lines, such as E1/T1 line, ISDN/PSTN line.The grounding screw of Quidway AR 28 Series Router, which is marked with groundinglabel, is located near the AC power socket and its switch on the rear pannel of thechassis, as shown in the following figure:Power switch AC input Grounding screwFigure 4-5 Grounding screw of the router4-5

Installation ManualQuidway AR 28 Series RoutersChapter 4 Installation of the RouterUse a PGND wire to connect the screw to the earth ground, and the groundingresistance should not be greater than 5-ohm. Likewise, if the router is installed in a19-inch standard rack, this rack is required to be grounded too.Caution:When the router is in normal operation, it is required to be well grounded. Otherwise, the router cannotreliably avoid lightning, which may damage the router itself and even the peer device.4.4 Connecting the power cordThe user is provided with two types of Quidway AR 28 Series Routers: AC-poweredand DC-powered.

Different signaling standards are supported in these two modes.V.35 and V.24 (RS232) support synchronous operating mode, while V.24 (RS232),support the asynchronous operating mode. The maximum transmission distance andbaud rate of the signal vary with the operating mode.Table 4-9 Transmission rate and transmission distance of V.24 (RS232)/V.35 cableV.24 (RS232) V.35Baud Rate (bps)MaximumTransmissionDistance (m)Baud Rate (bps)Maximum TransmissionDistance (m)2400 60 2400 12504800 60 4800 6259600 30 9600 31219200 30 19200 15638400 20 38400 7864000 20 56000 60115200 10 64000 50- - 2048000 30Caution:The baud rate should not exceed 64kbps when the V.24 cable operates in synchronous mode.2) DTE and DCE4-14

Installation ManualQuidway AR 28 Series RoutersChapter 4 Installation of the RouterSynchronous serial interface can operate in both DTE and DCE mode. For two devicesconnected directly, one should operate in DTE mode, and the other should operate inDCE mode. The device at the DCE side provides a synchronous clock and specifiesthe transmission rate, while the device at the DTE side accepts the synchronous clockand communicates at the specified baud rate. Usually, the router serves as a DTEdevice. To determine whether the device connected to the router is a DTE or DCE,please refer to the manual that came with the device. Also the following table will behelpful in identifying DTE and DCE. Usually, the PC or Router serves as a DTE deviceand the Modem, Multiplexer or CSU/DSU serves as a DCE device.In general, the asynchronous serial interface is connected to an external Modem or aTerminal Adapter (TA) to work as the dial-up interface. In this case, it is unnecessary todetermine whether the device is DTE or DCE, and just choose an appropriate baudrate.For the operating mode configuration of the synchronous/asynchronous serial interface,please refer to VRP3 Operation Manual.II. Synchronous/Asynchronous serial interface cableThe WAN interface of the router is a DB50 receptacle. Proper connection cable needsto be selected for the protocol applied. By far, 4 types of synchronous/asynchronousserial interface cables are available. One end of all the 4 types of cables is DB50connector, the other end (network end) varies with the cable type, which can be:• V.24 (RS232) DTE cable: DB25 (male) connector• V.24 (RS232) DCE cable: DB25 (female) connector• V.35 DTE cable: 34PIN (male) connector• V.35 DCE cable: 34PIN (female) connectorCaution:The above 4 types of cables are optional. The user must purchase the needed cables along with the router.Otherwise, they will not be provided.The following figures show the cable assembly of all 4 types:• V.24 (RS232) DTE cable assembly4-15

Characteristics of the command line interfaceThe command line interface of Quidway Series routers provides a number ofconfiguration commands, which can be used to configure and manage the router. Thecommand line interface has the following characteristics:• Performs the local configuration through CON port.• Performs the local or remote configuration through telnet command, which can beused to directly log on and manage other routers.• Configures the router through the terminal (herein refers to the asynchronousinterface, including those connected to the AUX port and AS port).• Configures the hierarchical user protection (includes guest, operator,administrator) . Only administrator users are authorized to configure and managethe router, so that unauthorized users would not be able to invade the routerillegally.• Users can enter anytime to get online help.• Provides network diagnostic tools, such as Tracert and Ping, to quickly diagnosethe availability of the network.• Provides all kinds of detailed debugging information to diagnose network faults.• The command line interpreter adopts fuzzy search for the keywords of thecommand. If the user enters the conflict-free keyword for a command, thecommand will be interpreted accordingly. For example, for a display command,the user can just enter .II. Command line interfaceThe command line interface of Quidway Series routers provides plenty of configurationcommands. Hierarchical user protection is adopted to prevent unauthorized users fromillegal invading. In the system view, to facilitate the management of the router, allcommands are grouped. Each group corresponds to a view (please see VRP3Operation Manual for details). The user can use these commands to switch betweendifferent configuration views. In general, only certain commands can be executedunder a particular view. But some common commands (such as ping, displaycurrent-configuration, interface) can be executed in all views.5.2.3 Naming and Arranging Interfaces1) Slot numbering5-7

Installation ManualQuidway AR 28 Series RoutersChapter 6 Router MaintenanceEnter your choice(1-3):13) Select an application to boot the router.Routers with Flash over 8 MB provide dual image function. That is, the system definesthree application files for booting the router by default: main application file, backupapplication file, and secure application file. If you have downloaded these threeapplication files in Flash, the system will select one in sequence to boot the router. Ifyou wish to change the sequence or the boot file, you can make modification in theBoot ROM menu.The default names, types, and select sequence of main, backup, and secureapplication files are described as follows:• Main application file: default name main.bin, file type M. By default, the systemutilizes this file to boot the router.• Backup application file: default name backup.bin, file type B. The system utilizesthis file to boot the router if the main file fails.• Secure application file: default name secure.bin, file type S. The system utilizes itto boot the router if the backup file fails. The system prompts booting failure if thesecure application file fails. Note:• Only the application files of M, B, and S types can be used to boot the system. Applications of N/A type,that is, non M, B, or S type, cannot be used to boot the system.• The file names of the applications in Flash can be modified using commands after they are started.Refer to “System Management” for detailed commands. The file types of M, B, and N/A applicationscan be modified in Boot ROM menu, or by commands after the applications are started. Theapplications of S type do not allow modification in file type.• Secure application file is the last precaution against system booting failure; therefore, it does not allowmodification or adaptation from other files. You can only download it from Boot ROM and specify itsname as secure.bin. If you use the rename command to change the secure file name after the systemis booted, the file is removed from Flash and you need to download it again.• Only one M file, one B file, and one S file can exist in Flash. For example, if a file is both M file and B file,it is impossible to have another M file or B file in Flash. If the file type of another file is changed to B, thefile of both M and B must be changed to M file.The following menu is displayed if you select 3 in the Boot ROM menu.

Installation ManualQuidway AR 28 Series RoutersChapter 7 TroubleshootingChapter 7 Troubleshooting7.1 Troubleshooting of the Power System1) FaultPOWER LED is OFF.2) TroubleshootingPlease check:• Whether the power switch of the router is turned on.• Whether the power supply switch is turned on.• Whether the power cord of the router is properly connected.• Whether the power supply matches the requirement of the router.Caution:Do not hot swap the power cord. After having checked the items above, if the POWER LED is still OFF,please contact the agent.7.2 Troubleshooting of the Configuration SystemAfter the Power-On Self-Test (POST) of the router, if the system operates normally, thestart-up information should be displayed on the console terminal. If the configurationsystem has some faults, the terminal may not display anything or may display onlyillegible characters.I. Troubleshooting of “nothing being displayed on the terminal”1) FaultAfter the POST of the router, the terminal does not display any information.2) TroubleshootingStep 1: please check:• Whether the power system is normal.• Whether the console cable is connected correctly.7-1

Installation ManualQuidway AR 28 Series RoutersChapter 7 TroubleshootingStep 2: If no problems are found after performing the above checks, it is likely to be theproblem of the console cable or the terminal (e.g., the HyperTerminal) parameters.Please check the cable or the parameters.II. Troubleshooting of “displaying illegible characters on the terminal”1) FaultAfter the POST of the router, the console terminal displays illegible characters.2) TroubleshootingPlease verify whether the terminal (e.g., the HyperTerminal) parameter settings are asfollows: Baud rate: 9600, Data bits: 8, Stop bit: 1, Parity: None, Flow control: None andTerminal emulation: VT100 If the parameter settings differ from the above values,please reconfigure.7.3 Troubleshooting of SDRAMI. Troubleshooting of “nothing being displayed on the terminal”1) FaultAfter the POST of the router, despite the normal power system (the POWER LED is ON)and proper connection of the console cable, there is no display on the console terminal.2) TroubleshootingIf the user is sure that the power system and configuration system have no faults,please contact the agent of Huawei Technologies Co., Ltd. With his consent, open thechassis to check whether the SDRAM has become loose. If that is the case, you mayremove and reinstall the SDRAM. For the operation method, please refer to Section 6.2“Maintaining the Hardware” in this manual.II. Troubleshooting of repeated reboot1) FaultFault 1: After the information “Now testing memory...” appears, the system restartsrepeatedly.Fault 2: After displaying the information “System now is Starting ...”, the system restartsrepeatedly, and sometimes gives a prompt message “Copied program error”.2) TroubleshootingGenerally, such faults are caused by the damage to SDRAM. If the SDRAM is seriouslydamaged, the problem will be found while testing the memory, and the system willreboot. If the SDRAM is slightly damaged, the problem will be found during the processof system starting, and the system will reboot, giving the prompt message “Copiedprogram error”.7-2

Installation ManualQuidway AR 28 Series RoutersChapter 7 TroubleshootingThe user can decide whether the SDRAM has fault by checking the LED status of therouter. During the router’s POST, the SLOT0 to 2 LEDs and SERIAL0 LED will be ONfirst. In this case, if the SLOT0 and SLOT1 LEDs light, it can be concluded that theSDRAM test has failed.If the SDRAM is damaged, replace it with a new one (before opening the chassis,please contact the agent of Huawei Technologies Co, Ltd. and get his permission tocontinue with the operation). For the operation method, please refer to Section 6.2“Maintain the Hardware” in this manual.7.4 Application Software UpgradeI. Fault 11) FaultWhen upgrading the VRP software using the TFTP approach, the system displays thefollowing message:Loading... tftpGet: Error occurred while transferring the file.An Error Occurred!:tftp transfer failed: error 0x43download error!!!Something is wrong. Please check.2) TroubleshootingThe symptom described above means that the new software version has not beenloaded. Fault isolation can be carried out from three aspects:• Check the TFTP server to see whether information can be sent. If not, the problemis likely to result from an incorrectly-configured TFTP server IP address. In thiscase, make sure that IP address of the TFTP server is the IP address of thenetwork interface on the PC, to which the Ethernet interface is connected. (For theprocedure of selecting an Ethernet interface for TFTP upgrade on AR 28 Routers,refer to 6.1.4.)Run the winipcfg command and the system will prompt the IP address of the Ethernetinterface.• If Windows prompts “The system detected conflict between the IP address xxxxand the system hardware address xxxx” in this case, it is very likely that the IPaddress of the TFTP server was incorrectly assigned to the upgrading Ethernetinterface on the Router.• Check the TFTP server. If it prompts “The system cannot find the specified file”, ,check whether the path set on the TFTP server and the file name (including theextension) of the application software set on the Router are correct.Upgrade the application software again after the problem is solved.7-3

Installation ManualQuidway AR 28 Series RoutersChapter 7 TroubleshootingII. Fault 21) FaultWhen upgrading the VRP software using the TFTP approach, and the system displaysthe following message:Loading...NET download completed...read len = [05567609]The downloaded software is not a valid version.Please download the correct version.Press key when ready.2) TroubleshootingAR 28 Series Routers should be loaded with different application software versions.The problem described above is likely to result from a mismatch between theapplication software version and the router model. In this case, contact your agent toobtain the correct software version and upgrade it again.If the improper software has been loaded, the Router cannot start or work correctly. Inthis case, select Xmodem or TFTP mode in the boot menu to restore/upgrade thesoftware version (FTP upgrade mode cannot be used here).If similar symptoms present when upgrading the software with other approaches, solvethe problem with reference to this example. Note:The bar code labeled on the Router host and the MIM contains the relevant manufacturing andmaintenance information. If you want to repair the device, inform your agent of the bar code on theproblem device.7-4
