H8DM3-2/H8DMi-2 User's Manual
PCI-X Slot Speed
Jumper JPXA1 on the H8DM3-2/
H8DMi-2 is used to change the speed
of PCI-X slots #1 & 2. Jumper JPXB1
is used to change the speed of PCI-X
slot #3. See the tables on the right for
jumper settings.
Note: JPXA1 controls the speed for PCI-X slots #1
and #2. JPXB1 controls the speed for PCI-X slot #3.
The default setting for both is Open (Auto).
Compact Flash Master/Slave
The JCF1 jumper allows you to assign
either master or slave status a compact
fl ash card installed in IDE1. See the
table on the right for jumper settings.
Power Supply Fail Detect
Enable/Disable
The system can notify you in the event
of a power supply failure. This feature
assumes that redundant power supply
modules are installed in the chassis. If
you only have a single power supply
installed, you should disable this func-
tion with J3P to prevent false alarms.
See the table on the right for jumper
settings.
SAS RAID Select
JPS1 allows you to select between
SR RAID, which is the default and
enables SAS RAID, or IT RAID, which
treats SAS drives as non-RAID drives
and requires a fi rmware fl ash. See
the table on the right for jumper set-
tings and the following page for the IT
fi rmware fl ash procedure.
