Powering on the Tape Library
Configuring the Tape Library
Setting the SCSI IDs for the Tape Library and Drives
All SCSI daisy chains must be terminated at the last unit attached to the SCSI
bus. Also, a terminator is built in to all SBus SCSI cards and to all host systems
to terminate that end of the bus. The regulated terminators must be used for all
68-pin SCSI buses having fast SCSI drives on a fast SCSI host.
SCSI Termination Guidelines
•
The SCSI device at the end of a daisy chain must be electrically terminated.
•
Only the last device in a SCSI daisy chain is terminated.
If the tape library is not the last physical device on the SCSI bus, plug a SCSI
cable into each connector. If the tape library is the last physical device on the
SCSI bus, plug a SCSI cable into one of the connectors and the appropriate
SCSI external terminator into the other connector.
If you are connecting the tape library to a single SCSI bus, you must install the
SCSI bus jumper block into the middle two connectors. If you are installing the
tape library on two SCSI buses, the SCSI bus jumper cable is not needed.
After connecting the tape library to your Sun system, turn the power on to the
tape library. See the Facilities Planning and Installation Guide for information on
how to power on the tape library.
You should next configure the tape library by setting the SCSI IDs (addresses)
for the library and drives.
See the Facilities Planning and Installation Guide for information on how to set or
change the SCSI IDs for the ETL 4/1000 library and drive.
