Filler Panels
When you have fewer drives than the hot-swap mass storage cage supports, a
1-inch filler panel must be inserted in each empty disk location. Filler panels
ensure that drive cage has the proper ventilation and air flow. Remove the filler
panel when you insert a new drive.
CAUTION The filler panels serve an important purpose by helping the
internal components ventilate and preventing excessive
electromagnetic radiation. If these fillers are left out of the
drive shelves, thermal damage and/or excessive EMI could
occur.
Drive Spacers
When your drive cage holds a mix of 1-inch and 1.6-inch drives, you may need to
add 0.5-inch drive spacers. The drive spacer fills the gap between adjacent drives
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 4, 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.
