6 Product Overview
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 tape drive has two shielded 68-pin HD SCSI
connectors on the rear panel and the FC tape drive has one FC connector. The connectors are used
for connecting the tape drive and the StorageLibrary 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 networking in support of the Web Client. It allows you to connect the StorageLibrary 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.
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 (Front Panel Interface, FPI). The Web Client is a remote management interface
that allows users to view and perform library functions from remote sites and is accessible through a
browser. The front panel interface and the Web Client contain a similar Operator interface and
functionality. For more information about the front panel and the Web Client interface, see
Information
about the Operator Interfaces .
ADI Bridging and LUN
The StorageLibrary implements Automation Drive Interface (ADI) bridging with Logical Unit
Numbering (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.
