We are operating a number of Dell M1000 blade chassis, each with 2 Cisco ws-cbs3130g-s switch modules. Most are operating fine, but I have one chassis for which the Cisco modules don’t complete their boot. When booting, the STCK light is constant green, and the SYST light flashes for a minute, then both light constant (indefinitely). With either a direct terminal connection or via the CMC command line (connect -m switch-1), there is no activity on the terminal at all (terminal and settings tested on working switches, and all is well).
The curious part — out of 6 chassis, each with two 3130s, I have 4 switch modules that demonstrate the same exact failure mode as described above. I also tried using a spare chassis, loaded with these switch modules (assuming the chassis might be the issue) — same thing.
When viewing these switches via the CMC web interface, they all show as healthy (?), and can be reset via the web interface, but am unable to successfully set dhcp or static IP via the web interface — no errors are shown, but configs are not changed in the interface.
I find it difficult to believe that all 4 switch modules hard failed the same way. Possibly the firmware is corrupt on these?
Any advice or ideas are appreciated.
Thanks!
