Variable-Speed Fans<br />

A variable-speed fan is identified by the following features:<br />

CABINET (Cabinet Sensors)<br />

● A fan and air filter assembly with product code ED-67077-30, Group 4 or greater, labeled<br />

on the front of the carrier<br />

● A 5-pin white connector mounted next to each fan on the fan assembly cover plate for<br />

speed control and alarm circuitry<br />

● A 2-pin black -48 V power connector to each fan<br />

● A power filter (ED-1E554-30, G1 or G2) located in a metal box mounted behind the fans on<br />

the right-hand cable trough as you face the rear of the cabinet<br />

● The AHD1 circuit pack and the two S4 sensors used with older fan assemblies are absent.<br />

Alarm leads from each fan are tied together into a single lead that registers a minor alarm<br />

against CABINET whenever a fan’s speed drops below a preset limit or fails altogether.<br />

Note: The<br />

Note: Fan/filter<br />

Note:<br />

front fans may run at a different speed than the rear fans since they are<br />

controlled by different sensors.<br />

Note:<br />

replacement procedures for the CMC1 and G600 media gateways are<br />

to be found under Variable-speed fans Maintenance Procedures (03-300432).<br />
