StorageLibrary Installation and User Guide 17
Guidelines for Connecting the SCSI Cables
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 state 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 StorageLibrary.
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 Cables
1. Install 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 for all tape drives on the
SCSI bus. Secure the cable with the thumbscrews 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. Connect 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 turning 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 outlet 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 fuse 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 this procedure if you are installing a library that includes Fibre Channel tape drives.
