Corrective action
Replace the module.
If a fan fails, replace the fan tray
as quickly as possible to maintain
high-availability operation. Failure to
replace the fan tray can cause the
chassis to overheat. You can replace
a fan tray in the 8306, 8310, 8006, or
8010 chassis with the power on or off.
