PCI-X Bus Speed Setting
Jumpers P2 and JP4 are used to set
the speed of the PCI-X bus. The
default setting is PCI 66 MHz (the
other settings are to support future
PCI-X cards.) See the table on the
right for jumper settings.
33 MHz PCI Enable/Disable
If you wish to use 33 MHz PCI
cards, close J4 to force the 133
MHz PCI-X slot to run at 33 MHz.
See the table on the right for jumper
settings.
Note: if you force the slots to 33
MHz, you must set the PCI-X Bus
Speed jumpers (above) to the low-
est speed.

SCSI Termination Enable/
Disable
Jumpers JPA1 and JPA2 allow you
to enable or disable termination for
the SCSI connectors. Jumper JPA1
controls SCSI channel A and JPA2
is for SCSI channel B. The normal
(default) setting is open to enable
(teminate) both SCSI channels. See
the table on the right for jumper set-
tings.
