Replacing the Fan Power Filter
The fan power filter (ED-1E554-30) is a metal box located behind the fans on the
right-hand cable trough as you face the rear of the cabinet. It is absent with
constant-speed fan assemblies.
!
CAUTION:
The fan power filter can be replaced without powering down the cabinet. To
avoid damage, you must use the following steps in the order shown. Note
that the J2F/P2F connectors on the power filter must not be connected
whenever connecting or disconnecting the J2/P2 connectors on the fan
assembly.
1. Access the power filter through the rear cabinet doors.
2. Connect the grounding wrist strap to yourself and the cabinet. The fan
alarm circuit can be damaged by ESD.
!
CAUTION:
Failure to disconnect the J2F connector on the filter before the J2
connector on the fan assembly can damage the fan alarm circuits.
3. Disconnect cabinet local cable connector J2F from the P2F connector on
top of the power filter.
4. Disconnect cable connector J2 from the P2 connector on the fan assembly.
5. Loosen the power filter mounting screws using a 5/16” nut driver and
remove the filter.

Failure to connect the J2 connector on the fan assembly can damage
the fan alarm circuits.

connector on the fan assembly.
7. Mount the new power filter on the screws and tighten.
