Upgrading to a Redundant Power Supply

Upgrading to a Redundant Power Supply
Remember to:
If you are adding redundant power to your library, you need to use
redundant power supplies on all library levels. All power supplies
must either be redundant or standard. Mixed power supplies are
not supported.
1. Disconnect all power cords from the library.
2. Remove the power supply that is shipped with the library by
loosening the two thumbscrews screws and pulling the module
straight out (see Figure 1-5 on page 1-15).
3. Install the redundant power supply module by aligning the bottom of
the module with the bottom of the power supply bay (see Figure 1-5
on page 1-15).
4. Fully insert the power supply module into the back of the power
supply bay.
5. Tighten the two 6-32 x .25 T15 screws to secure the module to the
library.
6. Reconnect the power cords to the bottom of the power supplies.
7. Ensure the individual power supply units are fully installed inside
the power supply module. The LEDs on each supply will be solid
green when the supply is online. See Table 3-9 on page 3-16 for more
information on the power supply LEDs.
