FAN-180A Series Fan Modules

Version Mapping

The FAN-180A series fan modules are classified into two types depending on the airflow designs: FAN-180A-B (B: back-to-front airflow, air exhaust on fan module panel) and FAN-180A-F (F: front-to-back airflow, air intake on fan module panel).

Table 4-25 describes the mapping between switch models and FAN-180A series fan modules.

Appearance

Figure 4-25 shows the appearance of a FAN-180A-B fan module, and Figure 4-26 shows the appearance of a FAN-180A-F fan module.

Each FAN-180A fan module has one counter-rotating fan, which has a pair of blades.

Function

A FAN-180A fan module consists of a fan tray, a fan, and a fan monitoring unit. FAN-180A-B and FAN-180A-F fan modules use different airflow designs but have the same functions. Table 4-26 describes the functions of them.

Table 4-26 Functions of a FAN-180A fan module

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
Heat dissipation	FAN-180A-B: back-to-front airflow FAN-180A-F: front-to-back airflow

Panel

Figure 4-27 and Figure 4-28 show the panels of FAN-180A series fan modules.

Table 4-27 describes the indicator on a FAN-180A fan module.

Table 4-27 Indicator description

Indicator	Color	Description
STAT: running status indicator	-	Off: The fan module is not running.
	Green	Blinking: The fan module is working properly.
	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.
