HP StorageWorks DAT Tape Drives User Guide - USB (April 2005)
Before you start8
How do I connect the drive to my server?
For optimum performance the drive should be connected to a USB 2.0 port and it should be the only
device on the USB bus. Although the tape drive will function on USB 1.1, performance will be
severely degraded. See also ”Verifying USB installation for optimum performance” on page 42.
Appropriate USB cables are supplied with your tape drive.
NOTE: For internal drives, the USB 2.0 connection may be via an internal port on the server’s
system board (as in many newer ProLiants servers) or an external port on the server’s rear panel.
What are the mounting requirements for an internal tape drive?
Mounting bay
You need one industry-standard, 5¼-inch, half-height bay in which to install the
HP StorageWorks DAT tape drive. Power requirements are:
Mounting hardware
For many servers, no mounting tray or rails are required. Devices simply slide into the server’s
chassis and are fixed with screws. Other servers have built-in trays or rails.
Rail kits for a number of industry-standard servers may be available. For more details refer to:

.
Some servers use non-standard mounting rails and do not include spares. If this is the case with your
system, you will have to order these accessories from the server manufacturer before you can install
the tape drive.
