Fan Modules
The AT-CVFAN module, as shown in Figure 10, is designed for use with
the AT-CV5000 chassis. You can install the same fan module in either fan
slot labeled A or B, located at the rear of the AT-CV5000 chassis. For
proper operation, two AT-CVFAN modules are preinstalled in the
AT-CV5000 chassis.
Caution
The AT-CVFAN modules are field-replaceable; however, they are
not hot-swappable. Therefore, make sure to power OFF the chassis
before replacing the fan modules.
Note
The AT-CV5000 chassis operates correctly even with one faulty fan
module. However, it will not operate correctly if one fan is missing
because this changes the air flow.

Figure 11 illustrates the locations of the two fan modules at the rear of the
AT-CV5000 chassis.
