Hi all,
A have a stack Enterasys B5 with 4 equipments in the IDF. In some cases, some users told me that are out of the network and suddenly are on line again.

I made a review of the switches, and found this in the log:

So, my question is:

- is there a problem with the switch? I mean: IOS, firmware, cable o the appliance? do I have to upgrade the firmware? the info about this is this:

Chassis Serial Number: xxxxxxxx
Chassis Firmware Revision: 06.71.02.0008

IDF_P4(rw)->

UNIT 2 HARDWARE INFORMATION

I hope this info be usefull to help me to find the solution.

Hi everyone,

I had that problem and I realised that it was caused by one unit rebooted.

Hi Jason,

I will test the cables today during the night (in a maintenance window). I will disconnect and connect the stack configuration cables one by one in order to be sure that they don't have problems.

Also, I will change the power cable.

Acording to the info with the "show switches", this is the display:

IDF_P4(rw)->show switch Management Preconfig Plugged-in Switch Code
Switch Status Model ID Model ID Status Version
------ ------------ ----------- ----------- --------------------- --------------
1 Mgmt Switch B5G124-48P2 B5G124-48P2 OK 06.71.02.0008
2 Stack Member B5G124-48P2 B5G124-48P2 OK 06.71.02.0008
3 Stack Member B5G124-48P2 B5G124-48P2 OK 06.71.02.0008
4 Stack Member B5G124-24 B5G124-24 OK 06.71.02.0008

So, I assume is the same version.

Meanwhile I already extracted the files with the copy command.

I really don't know what the GTAC's phone number is. Please, can you provide me that information?

Thank you so much for your help.

Regards,

Manuel Pineda.
