3com 4400 Superstack

Hello everyone,


I am a newer with this stuff. I got issued with my 3com 4400 superstack.

Seems it is not stable. Sometime 1st switch can communicate with IMC Server and sometime it's detected down.

It will change to 2nd switch on stack. looks like looping to each other ( up and down). 

Each switch can ping each other but if 1st down..that 1st switch cant ping to outside...only can ping stacking switch itself and DS switch.

Issued just happen changes had been made. Its suddenly happen. It is related with loopback testing on DS switch?

Please help me.
