Boot Priority
The Server’s boot priority (BIOS search order for a boot drive) should be considered when selecting a
PCI slot on the system board. This is especially important if you are installing a board that requires an
early number in the boot order. The board's boot priority is set by its slot location in the boot order.
See Figure 7-3.
The embedded SCSI controller consists of two channels, A and B. Channel A is typically used to
control the internal SCSI drives. Channel B is typically used to control the external SCSI devices or
used with Channel A to create disk duplexing. On each SCSI channel, the HP Server scans for a boot
device starting at device ID 0 and works up from there.
By default the HP Server searches for boot devices in this order:
1. SCSI
2. PM
3. SM
4. PS
5. Other Boot Devices
IDE DVD drive
Flexible disk drive
6. PCI slot 1
7. PCI slot 2
8. PCI slot 3
9. PCI slot 4
10. PCI slot 5
11. PCI slot 6
12. PCI slot 7
13. PCI slot 8
14. PCI slot 9
15. PCI slot 10
Installing Accessory Boards
The HP Server has eight hot swap PCI board slots and two non-hot swap PCI board slots.
Expansion slot covers must be installed on all vacant slots to maintain the electromagnetic
emission characteristics of the server and to ensure proper cooling of the system. The
following procedures detail the steps required to install both types of boards.
Installing a Hot Swap PCI Board
The HP Server has eight hot plug PCI I/O slots in the I/O Baseboard. You can replace a hot plug PCI
I/O board without shutting down the server. However, you must use the operating system or a
resident GUI to shut down or power off the PCI I/O board before you replace it.
The PCI hot-plug (PHP) is a rotating plastic mechanism that actuates a switch located on the PCI hot
plug LED board. Each PCI slot has four indicator LEDs: two on the outside and two on the inside of
