Краткое Руководство По Установке для 3com S7906E

 

6-19 

z 

The software of the SRPUs and LPUs must be consistent so that the S7900E series can work 

normally. 

z 

After upgrading the host software of the SRPUs of the S7900E series, you must reboot the LPUs to 

synchronize the software of the LPUs with that of the SRPUs. 

z 

You are recommended to reboot the whole system after upgrading the software of the SRPUs. 

 

If an upgrade fails, the system runs the original version. In this case, you need to check whether the 

physical ports are well connected. 

1)  If no, reconnect them correctly and restart the upgrade. 

2)  If yes, check the information displayed on the HyperTerminal during the upgrade process for any 

error. If there is any input error, correct it and restart the upgrade. For example, 

z 

If the XMODEM is used for upgrade, the baud rate of the HyperTerminal is not changed back to 

9600 bps after you download the software by using a baud rate other than 9600 bps. 

z 

If TFTP is used for upgrade, the IP address of server or switch, the name of the file to be 

downloaded, or the working path of TFTP server is wrong. 

z 

If FTP is used for upgrade, the IP address of server or switch, the name of the file to be downloaded, 

the username, or the password is wrong. 

3)  If the upgrade fails when the physical connection is normal and no input errors are found, contact 

the local agents of 3Com for help. 

If you lose the Boot ROM password of the switch, contact the local agents of 3Com.
