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
