h. Install the cable channel cover. To install the cable channel cover, complete the following steps:
1) Position the cover over the retaining screws and align the larger openings in the cover with the
retaining screw heads.
2) Set the cover down over the retaining screws and slide it toward the rear of the rack so that the
screws are now located in the narrow slots.
3) Tighten the four retaining screws.
7. If power was previously applied to the rack, restore the -48V DC B side power to the PDP. If power was
not previously applied to the rack, apply power to both the A and B sides of the PDP.
8. Continue with “Installing the system component circuit breakers in the PDP” on page 37.
Installing the system component circuit breakers in the PDP
This section provides information about installing the component circuit breakers. Circuit breakers are
supplied with the device that you are installing.
About this task
DANGER: Only use circuit breakers that have been provided with the device that you are installing.
Using an incorrectly-rated circuit breaker may create a safety hazard.
Note: If the device you are installing is not provided by IBM, you must provide the properly-sized circuit
breakers.
Note: A few installed devices might only require either the A or B side circuit breaker to control the
device's power. If the device only requires an A or B side circuit breaker, install the circuit breaker to
match the location of the installed cable, i.e. if the cable is at location A4, the circuit breaker must be
installed in position A4.
Attention: Ensure that the circuit breaker is in the off position before inserting it into the circuit
breaker panel.
Procedure
1. Remove bottom screw holding the circuit breaker cover to the selected circuit breaker position on the
A side of the PDP. Set the screw and cover aside.
