Sam,
What do you mean exactly when you say "It failed". Sometimes ports will automatically shutdown when a certain threshold of error conditions exist. Is your connection clean when it is operational (errors, CRCs, collisions, giants, runts, buffer overflows, overruns, etc.). What if you connected the port back to Sw2 port 1. Does it work now? If so, try the other ports that were "dead". Do they work again? Have you cleared any counters or reset the switches since you've had these problems? What other types of troubleshooting have you performed? And furthermore, have you contacted 3Com technical support for their take on it?

Subject: 3COM Question
Hi Group,
Wanted to throw in this and let me know, what you Cisco Experts think about
this.
At my work, We have 3COM 9300 ( 12 port Fiber) switch. This Sw has Layer 3
capabilities. Upart from Default Vlan we created one more VLAN. Thats all.
No inter VLAN communication. We exhausted all 12 ports on Present Sw.
We went ahead and bought another 3COM 9300 Sw. When Hooked the second
switch, it was hooked as a cascading chain. Port 1 from Sw1 Connected to
Port 1 of Sw2 with Fiber Cross Over cable.
It worked for some time. May be 6 --- 8 Months. Then the Port1 on Sw2
Failed. We thought Port1 went bad on Sw2. We moved it to Port2. After a
Month Port2 on Sw2 Failed. We moved it to Port3 now. It has been working
Okay since then.
This Morning, Port4 on Sw2 failed. We moved it to Port5 on Sw2.
Is this a symptom of switch2 going bad one port at a time?. or there is a
missing Link.
Your Earliest Response will be Appreciated.
---Sam.
