Avaya 03-300430 User Manual

A variable-speed fan is identified by the following features:

●

A fan and air filter assembly with product code ED-67077-30, Group 4 or greater, labeled 
on the front of the carrier

●

A 5-pin white connector mounted next to each fan on the fan assembly cover plate for 
speed control and alarm circuitry

●

A 2-pin black -48 V power connector to each fan

●

A power filter (ED-1E554-30, G1 or G2) located in a metal box mounted behind the fans on 
the right-hand cable trough as you face the rear of the cabinet

●

The AHD1 circuit pack and the two S4 sensors used with older fan assemblies are absent.

Alarm leads from each fan are tied together into a single lead that registers a minor alarm 
against CABINET whenever a fan’s speed drops below a preset limit or fails altogether.

Note:

The front fans may run at a different speed than the rear fans since they are 
controlled by different sensors.

Note:

Fan/filter replacement procedures for the CMC1 and G600 media gateways are 
to be found under 

 Maintenance Procedures (03-300192).
