AT-FAN06 Fan Module
Installation of two AT-FAN06 fan modules are required in the
AT-DC2552XS. Each AT-FAN06 fan module is equipped with two, forced
air cooling fans The fans push air through the chassis from the front to the
rear. The AT-FAN06 fan module is ordered and shipped separately from
the AT-DC2552XS L2 Data Center Switch.
A view of the AT-FAN06 fan module is shown in Figure 10.

The components of the AT-FAN06 fan module are as follows:
 Captive screws - The two captive screws secure the fan module to
the chassis frame. See “AT-FAN06 Fan Module” on page 32 for
the fan installation procedure.
 Handles - The two handles are used to physically push or pull the
AT-FAN06 fan module into and out of the chassis. See “AT-FAN06
Fan Module” on page 32 the fan installation procedure.
 Intake Air Vents - The AT-FAN06 fan module has two fans which
pull air through the intake air vents to cool the chassis

air vents. See Figure 2 on page 20 for the location of the exhaust
vents.
