Today, the 3com1100 and 3300 in the data center suddenly showed light and went on strike. After the power is disabled, the system does not work. After the optical fiber module is unplugged, the system starts normally, but the new optical fiber module is also on. If there is no way to upgrade the software, try again. After the upgrade, the old optical fiber module will run normally !!!

Update process: 1. telnet to switch to view software version from system-> display

2. download the latest software 2.69 (s2s02_69.bin) from the website)

3. Open the TFTP Server

4. telnet to the vswitch from system> softwareupgrade and enter the address of the TFTP server. Press enter for the software name and then telnet to disconnect. Do not disable TFTP or disconnect the power of the vswitch.
