The external storage SE SCSI connector
• The I

0 Memory slot, which contains cache memory used by the embedded
RAID controller (Intel i960RN I/O processor) (32 MB standard, which can
be upgraded to 64 MB or 128 MB)
• The Remote Management connector, linking the I/O board to the external
connector on the rear panel
Guidelines
Use the respective NOS software utility to:
◊ Ensure the correct software drivers for the PCI boards are loaded
◊ Verify correct operation
Slots 1, 2, 3, and 4 are non-hot plugs; slots 5, 6, 7, and 8 are hot plugs.
For optimal performance, add hot-plug boards to slots 7 and 8, which are
the fastest slots (66MHz and 64 bit).
Consider the boot priority prior to installing accessory boards.
You can configure the NetServer to boot from a PCI accessory board
instead of the onboard SCSI channels by putting the board in slot 1.
You can configure the NetServer to boot from a PCI-based DAC inserted
into a PCI slot. Use the Symbios Configuration Utility to select a different
PCI slot when scanning for boot devices. Refer to Chapter 10,
"Configuring the HP NetServer."
Slots 7 and 8 accept universal boards. Universal boards automatically
switch to accept power from +5.0 or +3.3 VDC.
Do not attempt to install or remove non-hot plug PCI boards with the
NetServer in any kind of sleep state, or a system crash or hang may occur.
See Chapter 2, "Controls, Ports, and Indicators," in the "Sleep States"
section.
Some accessory board outputs may exceed U.S. National Electrical code
(NFPA 70) Class 2 or power source limits and must use appropriate
interconnecting cabling in accordance with the National Electrical Code.
(All Hewlett-Packard boards comply with Class 2.)
