Removing and Replacing a Fan Tray 57
Removing the Fan Tray from a Chassis
The Switch 4007 chassis contains one fan tray. The
fan tray contains four fans.
Fans in the power supplies help to ventilate the
Switch, but they are not designed to act as a
substitute for the dedicated fan tray.
To remove the fan tray from Switch 4007 chassis,
follow these steps:
1
Using a flat-blade screwdriver, loosen the two
spring-loaded screws that attach the fan tray to the
front of the chassis (Figure 26).

Face the front of the chassis, grasp the handle on the
fan tray, and firmly pull the fan tray toward you
(Figure 27).

CAUTION:
Before you completely remove the fan
tray, wait until all fans in the fan tray stop rotating.

Carefully pull the fan tray straight out from the
chassis.
