FAN-40SB Series Fan Modules

FAN-40SB Series Fan Modules

Version Mapping

The FAN-40SB series fan modules are classified into two types depending on the airflow designs: FAN-40SB-B (B: back-to-front airflow, air exhaust on fan module panel) and FAN-40SB-F (F: front-to-back airflow, air intake on fan module panel).

Table 4-9 lists the mapping between switch models and FAN-40SB fan modules.

Function

A FAN-40SB fan module consists of a fan tray, a fan, and a fan control unit. FAN-40SB-B and FAN-40SB-F fan modules use different airflow designs but have the same functions. Table 4-10 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 fans based on temperature of the chassis.

Hot swap

Supported

Heat dissipation
  • FAN-40SB-B: back-to-front airflow
  • FAN-40SB-F: front-to-back airflow

Color

Description

STATUS: fan 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 errors of dual in-line package (DIP) switches, short circuits, fan blades blocked, and fault of the fan module.
