The fans begin rotating the moment that you power on the chassis or
that you insert the fan tray into a powered-on chassis.

Visually inspect all installed fans to verify that each is turning without
interruption. If a fan is not running, shut the power off and remove
and reinsert the fan tray.
Operating Guidelines
Follow these operating guidelines for the CoreBuilder 9000 fans:
■
If one fan in the fan tray fails, replace the fan tray as soon as
possible.
■
Do not leave the fan tray partially out of the fan tray slot. Make
certain the fan tray is fully inserted into the slot.
CAUTION:
The
CoreBuilder 9000 Enterprise Switch 7-slot chassis sends
a fan fault message (known as a trap) and can continue to run if one
fan fails in the fan tray. Replace the fan tray as soon as possible if one
fan fails in the fan tray. If one fan in the fan tray fails and the
temperature is 45 °C (113 °F) or greater, a trap message alerts you to
replace the fan tray immediately.
