5 Installing a removable Ultrium
SCSI tape drive
NOTE:
Ultrium 1760 tape drives are not available as removable models.

If you are installing an internal Ultrium tape drive, please refer to
“ Installing an internal Ultrium tape drive ” on page 21.
If you are installing an external Ultrium tape drive, please refer to
“ Installing an external Ultrium tape drive ” on page 31.
Which rackmount systems can I use?
HP StorageWorks Ultrium removable tape drives are used in conjunction with the HP Tape Array 5300
system, which can be used with both full-height and half-height tape drives. The tape array is designed to
be installed into HP, IBM and other compatible 19” rackmount systems. It must be properly installed and
configured. Refer to your tape array documentation for further details.
Airflow requirements
The HP Tape Array 5300 is designed to provide adequate airflow for up to two full-height tape drives
(such as the Ultrium 1840, 960 or 460 tape drives) or up to four half-height tape drives. As long as the
tape array is fully populated, it will provide adequate airflow for your HP StorageWorks Ultrium tape
drives. If you have unused bays in the tape array, you must install the blanking plates provided with the
tape array. This ensures that there is adequate airflow to the drives. See the documentation with the
tape array for details on installing blanking plates.
You should ensure that ventilation is adequate at the front and rear of the tape array.
How do I connect the drive to my server?
The following guidelines apply:
• For optimum performance the drive should be the only device on the SCSI bus.
• If you daisy-chain devices, make sure that devices are of the same SCSI type and that each device
on the same SCSI bus has a unique SCSI ID and is terminated appropriately. Do not daisy-chain
more than two devices on the same SCSI bus. HP recommends that Ultrium 920 tape drives are
not daisy-chained. (There is no removable model for Ultrium 1760 tape drives.)
• Always terminate the SCSI bus.
• Do not attach the drive to the same SCSI bus as a your disk drive or to a RAID controller unless
you are connecting to a ProLiant server with a Smart Array 6i RAID controller.
The individual tape drives are connected to their host server via the high density LVD/SE SCSI connectors
on the back of the tape array. They do not require any SCSI cables to plug into the tape array. However,
suitably-rated cabling and terminators are required to connect the tape array with the SCSI host.
