FAN-031A Series Fan Modules

FAN-031A Series Fan Modules

Version Mapping

The FAN-031A series fan modules are classified into two types depending on the airflow designs: FAN-031A-B (B: back-to-front airflow, air exhaust on fan module panel) and FAN-031A-F (F: front-to-back airflow, air intake on fan module panel).

Table 4-1 describes the mapping between switch models and FAN-031A series fan modules.

Function

A FAN-031A fan module consists of a fan tray, and a fan. FAN-031A-B and FAN-031A-F fan modules use different airflow designs but have the same functions. Table 4-2 describes the functions of them.

Function

Description

Automatic fan speed adjustment

After the fan module communicates normally with the switch, the switch controls the speed of the fan based on temperature of the chassis.

Hot swap

Supported

Description

STAT: running status indicator

-

Off: The fan module is not running.

Green

  • Slow blinking: The fan module is working properly and communicating normally with the system.

  • Fast blinking: The fan module is working properly but has not established communication with the system.

Red

  • Steady on: The fan module has a hardware fault and must be replaced.

  • Blinking: An alarm has been generated, and you need to handle it accordingly. Common causes of this alarm include short circuits, fan blades blocked, and fault of the fan module.
