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.
