Chapter 20. Power Management Module replacement and
configuration
Contents
Replacement
The current Power Management Module is the APC MasterSwitch Power
Distribution Unit, Model AP9212. We call it the Power Management Module in
order to avoid confusion with the IBM Netfinity Power Distribution Unit, the
fourteen-outlet power distribution bars that fit into sidepockets on the mounting
rack and plug into the main power supply for the site. In this document, ’PDU’
will refer exclusively to the power distribution bars.
To replace the Power Management Module, you must remove the tray from the
cabinet.
Uncable the Power Management Module
1. Note the positions of all cable connections to the Power Management Module
2. Obtain the IP address of the Power Management Module
3.
Unplug the Power Management Module power cable from the PDU
4.
Unplug the remote power cables

Unplug the cables to the port server
Remove the tray from the cabinet
1. Remove the mounting screws from the front vertical cabinet rails
2. Retract the sliding bracket at the back of the tray. Retracting the bracket allows
you to slide the tray out the rear of the cabinet. The figure below shows the
location of the sliding bracket, but shows them being extended.
