HP 20-Feb manual Replacing the Redundant Power Supply Module

Replacing the Redundant Power Supply Module

Caution When replacing the entire power supply module, note that the library does not have redundant power backup until the new module is installed. See page 170 for the procedure for replacing individual power supply units.

1.Disconnect the power cords from the library. Contact the system administrator to ensure there is no activity on the SCSI bus.

2.Remove the power supply module by loosening the two 6-32 x .25 T-15 screws and pulling the module straight out.

3.Install the replacement power supply module by aligning the bottom of the module with the bottom of the power supply bay.

4.Fully insert the power supply module into the back of the library.

5.Tighten the two screws.

6.The replacement supply comes with the entire redundant power supply module and one individual unit. If you need to install an additional unit, install one of the units from the original power supply.

7.Reconnect the power cord to the power supply.
