Replacing equipment
Note: To disconnect the power plug, you must press a latch trip on the
front and rear of the plug. You may need to use a screwdriver blade
against the latch trip on the front of the plug.
7 Remove the six screws that position the PDU. Carefully pull the unit
straight forward out of the pedestal.
Installing equipment
1 Set the main circuit breaker on the replacement PDU to OFF (down).
2 Position the replacement PDU and gently push it into the pedestal.
Note: Be sure you push the unit straight back, so the connector on the
rear will seat properly with the blower unit connector. It may be easier to
position the PDU if you temporarily pull the blower unit out several
inches.

a Attach power plug J1 and the system monitor cable.
