2.0 PRODUCT INFORMATIONThe Protected Network Station (Figure 1) is a tabletop or rack-mountunit designed to hold two MDS transceivers, two power supplies, and aswitchover logic board that automatically selects between transceiver Aor B as the active transceiver. Manual transceiver selection may also bemade using a front panel switch.NOTE: When switchover occurs, a delay of approximately 30 secondsoccurs until the new radio initializes. It may take approximatelyone minute for the radio to re-establish a link with anassociated station.Additionally, certain network devices may require approximately20 minutes to detect that the MAC address has changedfor the IP address of the radio. This does not affect thedata-passing ability of the radio—only the ability to conduct aconsole management session.Invisible place holderFigure 1. Protected Network StationWith two transceivers and power supplies installed, the unit continues tocommunicate even if a failure occurs in one of the transceivers, or itsassociated power supply. This capability is important in mission-criticalapplications where uninterrupted service is required.2 MDS Protected Network Station 05-4161A01, Rev. D

At the time of publication, the following transceivers aresupported by the Protected Network Station:• MDS iNET/iNET-II Series Access Point• MDS iNET/iNET-II Series Dual Gateway Remote• MDS iNET/iNET-II Series Ethernet Bridge Remote• MDS iNET/iNET-II Series Serial Remote• MDS entraNET (Access Point only)• MDS Mercury (Access Point only)• MDS SD Series TransceiversThe unit is equipped with alarm connections on the rear panel that activatewhenever the standby transceiver is put online. These are “dry”(isolated) alarm contacts that may be connected to customer-suppliedexternal alarm equipment, such as a lamp or sounding device.2.1 Product FeaturesThe Protected Network Station provides:• Fully-protected capability—Standard chassis contains twotransceivers and two power supplies. A provision for anoptional redundant antenna port is also available.• Automatic switchover to alternate transceiver if a failure occursin the primary unit or its power supply.• Optional built-in battery backup for AC-powered units• Rear panel alarm connections for customer-supplied alarmequipment• Tabletop or 19-inch rack mount installation• Standard MDS transceivers used inside05-4161A01, Rev.

Alarm Equipment ConnectionsIf alarm equipment (lamp, sounding device, etc.) will be used with thestation, make the appropriate connections to the rear panel ALARM terminals.Normally NormallyClosedOpenAlarm CommonFigure 19. Rear Panel Alarm Contacts(For use when two radios are installed)The ALARM terminals are “dry” (isolated) alarm contacts that close (connectto the alarm common) when the Switchover Logic Board detectsthat operation has switched to the secondary radio. Figure 19 shows theconnection state in the absence of an alarm condition—the right pin isNormally Open (NO) and the left pin is Normally Closed (NC), withrespect to the Common terminal.The alarm contacts are rated for the following service: 0.5 A at 125 Vacor 1.0 A at 24 Vdc. The common terminal in the connector’s middle“floats” and is not connected to ground or any internal power supplyvoltage source.NOTE: The alarm functions are intended for use with a fully-populatedand enabled chassis (i.e., two transceivers, two powersupplies, and both power supply switches set to ON). The frontpanel switch should also be set to the AUTO position so that afault in the primary transceiver causes an automaticswitchover to the secondary transceiver. It is this switchoverthat applies power to the secondary radio and causes the alarmcontacts to change state.Manual switchover to the secondary transceiver may also beperformed with the front panel switch, but it immediatelycauses the alarm contacts to change state, as a failure isassumed in the primary radio.26 MDS Protected Network Station 05-4161A01, Rev.

4.1.3 “Mirrored Configuration” of TransceiversTo ensure proper operation after a switchover, it is important that bothtransceivers in a Protected Network Station have the identical operationalconfiguration profiles. This can be accomplished using a configurationfile of one transceiver to configure the second transceivermounted in the protected chassis. The following steps outline the configurationprocess. Please review the use of a terminal and TFTP programsin the radio transceiver’s manual before starting the procedure.1. Install transceivers in the chassis as described earlier. Apply powerto the Protected Network Station.2. Set the front panel RADIO SELECTION switch to “A”.3. Configure Radio A (upper unit) as appropriate. Save the configurationfile to a TFTP server as described in the transceiver manual.4. Set the front panel RADIO SELECTION switch to “B”. Download thesaved configuration file into Radio B (lower unit).5. This completes the configuration procedure. Set the front panelswitch to AUTO, re-install the top cover (if removed), and the unit isready for service.38 MDS Protected Network Station 05-4161A01, Rev. D

4.2 Initial MDS entraNET (P22)Programming and SetupThis section presents menu settings for MDS entraNET transceiversused in P22 Protected Network Stations. Only menus pertaining directlyto protected network operation are covered here. For a complete list ofradio commands and other operation details, refer to the transceivermanual (Part No. 05-4055A01).(For instructions on programming MDS iNET/iNET-II Series transceivers,see “Initial MDS iNET/iNET-II (P21) Programming andSetup” on Page 31.)NOTE: MDS entraNET radios used in a Protected Network Stationmust have firmware revision 2.3.7 or higher installed. Contactthe factory for firmware availability.4.2.4 Redundancy MenuRedundancy is available only at the AP. The Redundancy Menu is usedin protected installations where a backup transceiver can be immediatelyplaced online should a primary unit fail. This protects against “singlepoint of failure” scenarios. The Redundancy menu contains selectionsand settings that are used to manage redundancy functions.NOTE: The chassis uses a Switchover Logic Board (Part No.03-6061Axx). This board is similar in appearance to the oneused in MDS P20 configurations, but they are not interchangeable.Contact the factory for assistance with replacementboards.MDS entraNET (P22) Programming and Setup05-4161A01, Rev.

4.4 Initial SD (SDxP) TransceiverProgrammingNOTE: SDxP models are normally pre-configured at the factory. Thefollowing instructions are for use only in a replacement/spareradio has just been installed if the chassis.Use the following steps to configure the SD Series transceivers for ProtectedNetwork service. For complete radio configuration instructions,refer to one of the following reference manuals:• MS Models: 05-4670A01• ES and SS Models: 05-4846A014.4.8 “Mirrored Configuration” of TransceiversTo ensure proper operation after a switchover, it is important that bothtransceivers in a Protected Network Station have the identical operationalconfiguration profiles. This can be accomplished using a configurationfile of one transceiver to configure the second transceivermounted in the protected chassis. The following steps outline the configurationprocess. Review the use of a terminal and TFTP programs inthe radio transceiver’s manual before starting the procedure.1. From the x710 command line, enter INIT SDxP, where “x” is themodel type of the radio installed in the chassis (i.e., SD2, SD4, SD9,etc.). This initializes the radios and sets the following parameters:• ASENSE LO: Alarm sense is active LO for P-model operation.• AMASK FFFF0000: Causes only major alarms to activate the alarmline.• RXTOT 20: Receiver protection for unknown failures. If no datais heard for 20 minutes, an alarm is activated.For SD radios, it is especially important to set the following items:COM port, baud rates, IP and Ethernet settings, RADIO mode,MODEM setting, and TX and RX frequencies.Mirrored configuration can also be done manually by applying thesame commands on one radio first, and then repeating the sequenceon the second radio. This can be accomplished using configurationfiles on menu-controlled models. See the applicable transceivermanual for details.SD Series (SDxP) Programming and Setup05-4161A01, Rev.

5.0 TROUBLESHOOTINGThe internal radio LED status indicators are an important troubleshootingtool and should be checked whenever a problem is encountered.Consult the transceiver manual for a discussion of LED functions.When an alarm condition exists, the transceiver creates an alarm code ormessage that can be read on a PC terminal connected to the rear panelDIAGNOSTICS port. This information can be helpful in resolving manysystem difficulties. Consult the transceiver manual for descriptions ofalarm messages, and corresponding corrective actions.6.0 TECHNICAL REFERENCE6.1 Field-Replaceable Assemblies and PartsTable 3 lists field-replaceable internal assemblies and parts available toimplement repairs.
