I has this ENVIRONMENT Messages in my 3500 switch that I bought from ebay:
Error Message ENVIRONMENT-2-FAN_FAULT:System Fault:FAN FAULT is detected.
Explanation This message means that an internal fan fault is detected.
Recommended Action Check the switch itself, or use the show env privileged EXEC command to check if one or more fans on the switch have failed. Replace the switch at your convenience.
SWITCH-A#show env fan
FAN 1 is OK
FAN 2 is OK
FAN 3 is OK
FAN 4 is OK
FAN 5 is FAULTY
Should I return the switch or keep ip?
