Chapter 1: Overview

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.
