Verifying fan assembly FRU replacement

To determine if a fan assembly requires replacing, do any of the following:
• Check the system status LED. If the system status LED is flashing amber and green, it could mean
the fan has failed. The green power supply/fan LED will also flash in the event of failure. Check
the management interface and the error log for details on the cause of status.
• In Web Tools, check the Fan Status icon background color. It will be either yellow or red if the fan
has failed. When the fan is functioning correctly, the background color is green.
• Type the fanShow command at the command prompt to display fan status:
switch:admin> fanshow
Fan 1 is OK, speed is 7105 RPM
Fan 2 is OK, speed is 7258 RPM
