Power Supply; Interior Components - IBM System Storage TS3310 Setup And Operator Manual

SCSI tape drives are attached directly to a host. Fibre Channel tape drives can be
directly attached to a host or a Storage Area Network (SAN).
Drives mounted in sleds are installed into tape drive slots in the rear of the library.
If a tape drive slot is empty, a metal plate covers the empty drive slots to prevent
debris from entering the library.

Power Supply

The library supports single and redundant power configurations. Each 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. 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 1-2 on page 1-5) 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 1-2 on page 1-5) is located on every power supply
on a control module and expansion module. 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 8-10.
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 10-6
