SCSI Addressing
Different form-factor hot-swap disk drive modules can be mixed and
matched within the hot-swap mass storage cage. Because so many
different configurations are possible, the SCSI address assigned to
each module will be different depending on the particular
configuration.
See "Non-Hot-Swap SCSI addressing," below, for addressing
restrictions for non-hot-swap devices.
1. Open the drive module by pressing in on the locking latch at the
end of the drive ejector handle and pulling open the handle.
2. Choose a location in the hot-swap mass-storage cage and gently
slide the module into the cage. Stop when you feel resistance.
3. Slowly close the ejector handle. Verify that the pin behind the pivot
end of the handle engages the hole in the edge of the cage (see
figure at right).
4. With even pressure, gently close the ejector handle until the
Inserting a Hot-Swap Disk Drive Module
This HP NetServer supports both hot-swap SCSI devices,
installed in the hot-swap mass storage cage, and non-hot
swap SCSI devices, installed in shelves 3 and 4 (located
below the CD-ROM drive).
Use only Ultra2 (LVD), SCA-2 connector hot-swap devices in
the hot-swap mass storage cage. You can use any standard
(non-Ultra2) wide, 68-pin single-ended SCSI device in non-
hot-swap shelves 3 and 4, such as a removable hard disk or
a tape backup drive. Narrow (50-pin) SCSI devices are
supported in the non-hot-swap shelves, but require a 68-to-
50-pin cable adapter for connecting the data cable to the
device. (One adapter is provided on the SCSI cable behind
shelf 3.)
CAUTION
Do not mix Ultra2 devices with other SCSI
devices. Use only Ultra2 devices in the
hot-swap mass-storage cages. Use only
non-Ultra2 devices in the non-hot-swap
shelves (shelves 3 and 4).
Refer to the documentation that came with the SCSI
device for the jumper location and settings. Refer to the
Technical Reference Card, located in the pouch on the
inside of the NetServer cover, for the recommended SCSI
addresses.
The NetServer SCSI cable is terminated. Verify that no
added devices are terminated.

SCSI Addresses
Jumper Settings
Each SCSI device must have a unique SCSI
address. Devices connected to the SE connector
(those located on the non-hot-swap shelves) and to
the SCSI B connector (not used in the factory-
configured models) share one SCSI bus. Therefore,
each device connected to either of these connectors
must have a unique address (narrow devices may
use addresses 0-6; wide devices may use addresses
0-15, except address 7).
The figure to the right is typical of a SCSI hard disk
drive that may be used in this NetServer. Use this as
a general reference for jumper locations and
settings. Typically, jumpers A0, A1, A2, and A3
determine the SCSI address.

Removing a Hot-Swap Disk Drive Module
1. Let the drive spin down completely before removing it (about
1 minute).
2. Press in on the locking latch at the end of the drive ejector handle and
gently open the handle.
NOTE
For maximum storage density and to avoid
configuration problems, install hot-swap drives in
consecutive locations only, beginning with the
leftmost location in the mass-storage cage.
Both half-height (1.6-inch) and low-profile (1-inch) devices may be
installed in the hot-swap mass-storage cage. There are two different
height hot-swap trays available to accommodate different form-factor
devices.
Six low-profile devices or four half-height devices, or combinations of
these two devices may be installed in the hot-swap mass-storage cage.
Because of the height difference between half-height and low-profile
Hot-Swap Module Configurations and SCSI Addresses
devices, some combinations of the two types require spacers to take up
space between devices. The figure below shows the possible
combinations of hot-swap devices possible. SCSI addresses are
assigned automatically depending on the location of a drive module
within the mass storage cage.
SCSI addresses listed here are for SCSI A channel only. Refer to the
for SCSI B channel addresses.

CAUTION
Do not operate this NetServer -- for even
short periods -- without a drive module,
filler panel, or drive spacer in every hot-
swap and non-hot-swap mass storage
location. Otherwise, damage to
components may result due to improper
cooling airflow.
