HP SureStore DAT
Installing an “e” Model Drive (external)
1-3
Before You Start: Check System Prerequisites
To install and use your new tape drive, you will need the following:
• SCSI host adapter
• SCSI cable
• Backup software that supports the tape drive
SCSI Host Adapter
You need a properly installed and configured SCSI host adapter or a built-
in SCSI controller on your computer’s motherboard (SCSI-2 or SCSI-3
compliant). Consult your supplier for details.
If you are installing on a Windows 95, Windows 98, Windows NT or Novell
NetWare system, you can use HP TapeAssure to check your computer’s
SCSI configuration, as directed on page 1-5.
HP SureStore DAT Drives and SCSI
All HP SureStore DAT drives, apart from the HP SureStore DAT40 are fast
narrow SCSI devices and should be connected to a single-ended (SE) host
bus adapter.
The HP SureStore DAT40 drive is an ultra wide SCSI device. For optimum
performance it should be connected to a low voltage differential (LVD) SCSI
host adapter. HP SureStore DAT40 drives may also be connected to SE
(single-ended) SCSI host adapters, but cable length will be restricted to the
SE rather than the LVD specification.
If you would like more information on SCSI specifications and configuring
your SCSI bus, read the “SCSI Background” topic in the “Before You Start”
section of the electronic User’s Guide on the HP SureStore Tape CD-ROM.
SCSI Cable
You need a SCSI cable that connects to your computer’s external connector.
For optimum performance, always use the supplied cable.
– The cable provided with DAT8e, DAT24e and DAT40e drives will
attach to a computer with a wide SCSI connector (68 pins). The cable
has been specified for use with LVD systems up to Ultra2 speeds.
– The cable provided with Tape 5000e drives will attach to a high-
density narrow SCSI connector (50 pins).
