Main Power Switch/ Fuse/Power Cord Connection
The main power switch is located at the rear of the library on the power supply bracket. The power
switch, the fuse holder (with a 250V 2A fuse) and the AC power cord connection are combined in one
common unit.
SCSI and Fiber Channel Interface Connectors
The library supports both SCSI and FC drives. The SCSI drive CRU has two shielded 68-pin HD SCSI
connectors on the rear panel and the FC CRU has one FC connector. The connectors are used for
connecting the tape drive and the StorageLibrary T40 to the host. These connectors can link to the
following:
A shielded male HD68 SCSI cable
A shielded male HD68 SCSI terminator
FC port cable
Ethernet Port
This port is for the Remote Management system and allows you to connect the StorageLibrary T40 to
a 10 BaseT compatible Ethernet network.
Battery Holder
The battery for the real time clock is located behind a plate at the rear of the library. A drive power
extension cable is found in the same location.
Back Panel Cover plate
If a drive bay is empty a cover plate covers the opening to prevent dust from entering the library.

Library Features

This section describes several features of the StorageLibrary T40.

Operator Interfaces

The front panel is located on the front of the library and allows users to work locally on the library via
the Operator interface. The remote management interface allows users to view and perform library
functions from remote sites and is accessible through a browser. The front panel and remote
management interfaces contain a similar Operator interface and functionality. For more information
about the front panel and the web interface, see

ADI Bridging and Logical Unit Numbering (LUN)

The StorageLibrary T40 implements ADI bridging with LUN addressing. This means that the library
controller does not have its own host interface, but SCSI commands to the library controller are sent
via one of the installed tape drives. The tape drive and the library controller will have a common SCSI
ID but different LUN numbers. The SCSI commands to/from the library controller are sent via the tape
drive's ADI port.
The purpose of the LUN interface is to eliminate the requirement for a host interface on the library
controller board.
