3com switches reboot every few minutes
Posted on 2004-09-24
3 of my office 3com switches, 48-port 3c17302, reboot every few minutes (such as 3 to 5).
These cause the servers and workstations to have 'unplugged' and 'plugged' status for the network adaptors (in Windows environments)
A few 24-port switches don't seem to have this problem.
Suspecting overloaded and transferred a few points to a number of unmanaged hubs.
The frequency has reduced but the problem still exist.
The stacked switches were then separated and connected to the cisco 3550 into a collapse backbone setup.
According to 3com engineer, after intending to return the equipments that were still under warranty, i needed to upgrade my firmware from version 2.02 to 2.10.
I managed to download and upgrade the firmware for one of the switches.
I hope to see that result on next Monday on whether the switch still reboot after the patch.
I am comtemplating to replace the 3com switch to 3com hub or get new cisco switches.
