StorageLibrary Installation and User Guide

Guidelines for
C
onnecting the SCSI
C
ables
1
Before the SCSI bus cable is connected to the
StorageLibrary
, make sure the
StorageLibrary
power switch is off.
2
Make sure your host system is in a s
tate where a new SCSI device can be safely connected to the
SCSI bus.
3
Do not exceed SCSI bus length restrictions.
a.
Add the length of all external and internal SCSI cables on the bus
.
b.
Add
26.4 cm (10.
4 inch) for the internal cable length in the
StorageLibr
ary
.
c.
The maximum allowed length of an LVD SCSI bus is 12 m (39 ft) if the number of
SCSI devices exceeds two.
4
Before the
StorageLibrary
is powered on and the system is restarted, make sure the SCSI bus is
properly terminated.
Connecting the
C
ables
1.
Instal
l the library in a rack
or
install
the tabletop
kit
.
2.
Connect the SCSI cables to the
tape drive
.
a.
On the bottom tape drive, connect a jumper cable to the top SCSI connector and then to the
bottom SCSI connector on the tape drive above it. Repeat this step fo
r all tape drives on the
SCSI bus. Secure the cable with the t
h
umbscrews on the connectors.
a.
Terminate the last device on the SCSI bus with the appropriate SCSI terminator.
b.
Connect a cable between the last tape drive on the SCSI bus and the host. Note that
there are limitations to the length of the SCSI cable.
3.
Connect your
Ethernet
cable to the
Ethernet
port on the rear of the library
.
This will give
remote
access to the library via the remote management interface. Push the cable
until
it snaps into
place. C
onnect the other end to a normal 10/100 BaseT Ethernet outlet.
4.
Connect a power cord to the outlet on the power supply on the rear of the library.
5.
Power on the library by t
urning on the rear power switch.
6.
Power up the host system.
7.
Verify communication with
all devices on the bus.
8.
Configure your library using the commands on the front panel. For configuration information, refer
to
Configuring
the
Library
.
Warning
Make sure the AC outle
t that you connect the
StorageLibrary power
cable into is
reliably earthed.
Adding the StorageLibrary
to an existing rack installation can cause a leaking
current fault condition because of the summation of the leaking currents.
For security, a 250V 2A fus
e is located near the power switch
.
Note
Tandberg
recommends that all external SCSI devices, including the
StorageLibrary
, are powered on before the computer system is re
-
started (Steps
5 and 6 above).
Connecting Library Cables (Fibre Channel)
Use th
is procedure if you are installing a library that includes Fibre Channel tape drives.
