<strong>Installation</strong> <strong>Manual</strong><strong>Quidway</strong> <strong>AR</strong> <strong>28</strong> <strong>Series</strong> <strong>Routers</strong>Chapter 7 TroubleshootingThe user can decide whether the SDRAM has fault by checking the LED status <strong>of</strong> 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 <strong>of</strong> 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 S<strong>of</strong>tware UpgradeI. Fault 11) FaultWhen upgrading the VRP s<strong>of</strong>tware 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 s<strong>of</strong>tware 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 <strong>of</strong> the TFTP server is the IP address <strong>of</strong> thenetwork interface on the PC, to which the Ethernet interface is connected. (For theprocedure <strong>of</strong> selecting an Ethernet interface for TFTP upgrade on <strong>AR</strong> <strong>28</strong> <strong>Routers</strong>,refer to 6.1.4.)Run the winipcfg command and the system will prompt the IP address <strong>of</strong> 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 <strong>of</strong> 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) <strong>of</strong> the application s<strong>of</strong>tware set on the Router are correct.Upgrade the application s<strong>of</strong>tware again after the problem is solved.7-3
