FAN-40EA Series Fan Modules

Version Mapping

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

Table 4-5 describes the mapping between switch models and FAN-40EA fan modules.

Function

A FAN-40EA fan module consists of a fan tray, two fans, and a fan control unit. FAN-40EA-B and FAN-40EA-F fan modules use different airflow designs but have the same functions. Table 4-6 describes the functions of them.

Table 4-6 Functions of a FAN-40EA fan module

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-40EA-B: back-to-front airflow FAN-40EA-F: front-to-back airflow

Table 4-7 describes the indicator on the panels of the FAN-40EA fan modules.

Table 4-7 Indicator description

Indicator	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.
