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 6-58 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. If you are replacing a module on the top level of the library, ensure
the stop bracket is removed from the top of the library. See
Figure 6-11 on page 6-29.
3. Remove the power supply to be replaced by loosening the two 6-32 x
.25 T15 screws and pulling the module straight out.
4. Install the replacement power supply module by aligning the bottom
of the module with the bottom of the power supply bay.
5. Fully insert the power supply module into the back of the library.
6. Tighten the two screws.
7. The replacement FRU comes with the entire redundant power supply
module and one individual unit (see Figure 6-33 on page 6-60). If you
need to install an additional unit, install one of the units from the
original power supply.
8. Reconnect the power cord to the power supply.
