or between a drive and a filler panel. Disk spacers can be mounted on 1-inch
low-profile drives or 1.6-inch half-height drives, so a drive spacer and low-
profile drive are the same size as a half-height drive, and a drive spacer and a
half-height drive are as large as two low-profile drives.
CAUTION The drive spacers serve an important purpose by helping the
internal components ventilate and preventing excessive
electromagnetic radiation. If these drive spacers are left out of
the drive shelves, thermal damage and/or excessive EMI
could occur.
Configurations
Figure 6-1 shows the supported configurations of SCSI hot-swap hard disk drives
in both versions of the NetServer. The arrows indicate the order that you insert
hard disk drives.
These configurations may use filler panels and drive spacers to close up the front
of the hot-swap mass storage cage. If there are gaps in the cage, the drives may
not receive the proper ventilation and could suffer thermal damage.
If you have an HP NetServer LH 3, add hard disk drives starting from the
bottom of the hot-swap mass storage cage. If you are using one or more
filler panels, insert them at the top of the cage.
If you have an HP NetServer LH 3r, add hard disk drives starting from the
left. If you are using one or more filler panels, insert them on the right
side of the drive cage.
NOTE Do not install a narrow SCSI drive in any location with a
SCSI address greater than 6. Narrow SCSI is limited to SCSI
addresses 0 - 6, and the NetServer will not be able to
communicate with a narrow SCSI drive.
