Power Supply
The library supports single and redundant power configurations. Each control
module must have at least one power supply. A single power configuration will
have a power supply installed in the left slot of each library module as viewed
from the rear. A redundant power configuration will have power supplies installed
in both slots of each library module.
The single configuration has a single AC line input and a single DC power supply.
The optional redundant configuration has dual AC line input and dual DC power
supplies. A power supply (3 in Figure 2-2 on page 2-5) can be hot swapped if the
library has a redundant power supply. A redundant power supply can be hot
added.
A power switch (4 in Figure 2-2 on page 2-5) is located on every power supply.
This switch is used to remove all power from the library for emergency and
service situations. Except in emergency situations, use the shutdown procedure
before switching OFF the power switch. For more information, see “Shutting Down
the Library” on page 7-39For more information, see "Shutting Down the Library" in
the Setup and Operator Guide.
The power system of the library contains the following components:
v Power supply
v AC power cord
The power supply has three light emitting diodes (LEDs) that provide status
information. These LEDs, located to the right of the power switch, are green,
amber, and blue in color.
v Green indicates a good AC or DC status.
v Amber indicates a degraded status.
v Blue indicates a potential fault. See “Interpreting LEDs” on page 7-16For more
information, see "Interpreting LEDs" in the Setup and Operator Guide.
