Application Software Upgrade 53
| The user can decide whether the SDRAM has fault by checking the LED |
| status of the router. During the router’s POST, the SLOT1 to 3 LEDs and |
| SERIAL0 LED will be ON first. In this case, if the SLOT1 and SLOT2 LEDs |
| light, it can be concluded that the SDRAM test has failed. |
| If the SDRAM is damaged, replace it with a new one (before opening the |
| chassis, please contact the agent of 3Com Corporation Co, Ltd. and get |
| his permission to continue with the operation). For the operation |
| method, please refer to Section 6.2 “Maintain the Hardware” in this |
| manual. |

Application | Fault 1: When upgrading the software using the TFTP approach, the |
Software Upgrade | system displays the following message: |
| Loading... tftpGet: Error occurred while transferring the |
| file. |
An Error Occurred!:tftp transfer failed: error 0x43 download error!!!
Something is wrong. Please check.
Troubleshooting: The symptom described above means that the new software version has not been loaded. Fault isolation can be carried out from three aspects:
■Check the TFTP server to see whether information can be sent. If not, the problem is likely to result from an
Run the winipcfg command and the system will prompt the IP address of the Ethernet interface.
■If Windows prompts “The system detected conflict between the IP address xxxx and the system hardware address xxxx” in this case, it is very likely that the IP address of the TFTP server was incorrectly assigned to the upgrading Ethernet interface 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 the extension) of the application software set on the Router are correct.
