HP D5970A - NetServer - LCII Installation Manual page 74

Chapter 6
All PCI boards without hot plug compliant drivers installed or removed in
slots P1 through P10.
1. Read the documentation included with each board and follow any special
instructions provided.
CAUTION To prevent a system crash or hang, never open the PCI
hold-down latch of a PCI slot with the HP NetServer powered
on. Always turn power off to the NetServer before opening the
PCI hold-down latch.
Only a PCI Hot Plug utility allows you to turn power off to the
slot, before opening the PCI hold-down latch with power
applied to the HP NetServer.
2. Perform the shutdown procedure listed in Chapter 3, "Opening and Closing
the HP NetServer" for the respective NOS.
NOTE
The power supplies will continue to provide standby current to
the HP NetServer until the power cable is disconnected.
CAUTION
Do not attempt to install or remove PCI boards with the HP
NetServer in any kind of sleep state or a system crash or hang
may occur.
3. If required, extend the HP NetServer out from the rack on its slides by
performing the necessary steps, including the safety precautions.
Refer to Chapter 3, "Opening and Closing the HP NetServer."
4. Access the I/O baseboard by removing the PCI access panel.
Refer to Chapter 3, "Opening and Closing the HP NetServer."
5. Consider the boot priority, before installing any accessory boards.
For details, refer to the topic "Boot Priority" and Table 6-1 earlier in this
chapter. If installing a SCSI controller board, the controller's priority (boot
order) is set by the board's slot location.
6. Identify the desired slot (P1 through P10) before installing the accessory
board. See Figure 6-1.
Ensure the board is being installed into a compatible slot.
