HP D7171A - NetServer - LPr Installation Manual page 59

Chapter 6
Use the appropriate NOS utility for the following:
To ensure that the correct PCI accessory board software drivers are
installed.
To verify that the board is operating correctly.
Slots 1 and 2 are used only for non-hot-plug accessory boards.
Slots 3, 4, 5, and 6, are used for hot-plug accessory boards. If non-hot-plug
supported boards are installed in these slots, the hot-plug feature is
disabled.
NOTE
Refer to the HP NetServer Navigator CD-ROM for a list of
compatible hot plug accessory boards.
For optimal performance, install accessory boards in Slots 5 and 6. These
are 64-bit, 66 MHz slots, which are the fastest of the slots.
CAUTION
Do not install 33 MHz with 66 MHz accessory boards in slots
3 through 6. Installing 33 MHz boards with 66 MHz boards
forces the bus to operate at 33 MHz, which in turn forces any
66 MHz boards to operate at 33 MHz.
Consider the boot priority before installing accessory boards.
l
You can configure the NetServer to boot from a PCI accessory board
instead of the onboard SCSI channel by installing the board in Slot 1.
l
You can configure the NetServer to boot from a PCI-based DAC installed
in a PCI slot.
l
Slots 5 and 6 accept universal PCI accessory boards. These boards can
automatically accept power from +5.0 VDC or +3.3 VDC.
l
Do not attempt to install or remove any PCI accessory boards with the
NetServer in any kind of sleep state. Doing so might crash or damage the
system. See the "Sleep States" section in Chapter 2, Controls, Indicators,
and Ports.
Some accessory board outputs might 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 accessory boards comply with the Class 2 code.)
