Verifying the power supply installation and operation
1. If AC power is plugged into the power supply and the library is turned on, both the white LED (2 in
Figure 76 on page 161) and the green LED (4 in Figure 76 on page 161) will be lit.
2. Use the Operator Panel or Management GUI to conîš´rm that the power supply is operating correctly. If
there was a power supply event, it should now be cleared.
Replacing a Base or Expansion controller card
CAUTION:
• Parts can be damaged by electrostatic discharge. Keep
parts in electrostatic containers until needed. Ensure
that you are properly grounded when static sensitive
components are touched.
• You must power off the library to install or replace this part
or damage can occur.
