[c-nsp] Catalyst 4507R Single Point of Failure

[Antonio Soares]

Group,

This is happening to a Catalyst 4507R:

%C4K_IOSMODPORTMAN-4-FANTRAYBAD: Fan tray has failed
%C4K_CHASSIS-2-INSUFFICIENTFANSDETECTED: Too few working fans in fan tray, the chassis will overheat. If not resolved, in 4 minutes
all line cards will be placed into Reset-Mode
%C4K_CHASSIS-2-INSUFFICIENTFANSSHUTDOWN: Resetting linecards due to fan tray failure
%C4K_IOSMODPORTMAN-6-MODULEOFFLINE: Module 3 is offline
%C4K_IOSMODPORTMAN-6-MODULEOFFLINE: Module 4 is offline
%C4K_IOSMODPORTMAN-6-MODULEOFFLINE: Module 6 is offline
%C4K_IOSMODPORTMAN-6-MODULEOFFLINE: Module 7 is offline
%C4K_IOSMODPORTMAN-6-FANTRAYGOOD: Fan tray is okay

I verified that only 1 out of 6 of the fans composing the Fan Tray is stopped.

Any way to stop this automatic shutdown ?

It's hard to understand why a Catalyst with Dual Supervisors and Dual Power Supplies will stop because of this.




Thanks.
