HP StorageWorks MSL4048 Tape Library getting started guide (AH560-96001, March 2007)

After installing the rails, slide the Library onto the rails.
Secure the front bezel to the rack using a #2 Phillips
screwdriver placed through the small holes in the
mounting bracket to tighten the captive screws on each
side of the Library.

Using the screws for your rack type, and a #3 Phillips
screwdriver, secure one rail to each side of the rack. Secure
the front and the back of each rail to the rack. The front of
each rail is straight and the back is angled, as shown.
Optional: Adding tape drives
7
With the tape drive upgrade kits, the Tape Library can
hold up to four half-height tape drives or two full-height
tape drives.
Add the new tape drive directly above the currently
installed tape drives. Remove one drive bay cover for a
half-height drive or two drive bay covers for a full-height
drive. Slide the tape drive into the bay until it is firmly
seated. Tighten the blue thumb screws to secure the drive
to the Library.
If you are unfamiliar with configuring parallel SCSI
devices, read the parallel SCSI configuration information
in the User and Service Guide on the documentation CD.
Follow these general guidelines when planning the
parallel SCSI configuration:
• The Ultrium 960 and 920 tape drives are Ultra320
SCSI devices. Only one Ultrium 960 or 920 tape drive
should be put on an Ultra320 SCSI bus. Putting an
Ultrium 960 or 920 tape drive on a slower bus or
putting two drives on the same bus may degrade
performance.
• The Ultrium 448 tape drive is an Ultra160 SCSI
device. Only one Ultrium 448 tape drive should be
put on an Ultra160 bus. Up to two Ultrium 448 tape
drives can be on an Ultra320 bus.
• Avoid putting the Library on the same SCSI bus as a
disk drive or SE device.
