Chapter 6 Installing Additional Boards Accessory Board Installation Guidelines The following sections provide the guidelines necessary to install the PCI accessory boards into the Server. NOTE Some full-length PCI boards may need a plastic "handle" (board extension) on one end to stabilize the board in the Server. If the board requires one and it is not installed, you may need to install the handle on the board, before installing it in the HP Server. See Figure 6-5. IRQ Settings The IRQ settings are automatically assigned and don't require user intervention. The HP Server uses the Plug-and-Play feature of the PCI boards to correctly assign its resources automatically. Installing a Disk Array Controller Board Adding a disk array controller board provides additional fault tolerance to your internal or external mass storage devices. If you plan on adding a disk array controller board to the HP Server tc2100, HP recommends installing the HP NetRAID-1M PCI board in slot 1 or 2 depending on the Server model (IDE or SCSI). When installing a disk array controller board, you may alter the Server's boot order to allow the Server to boot off one of the array's drives. This boot order can be changed under the Boot menu of the Server's (BIOS) Setup Utility. 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 accessory board's boot priority is set by its slot location in the boot order. See Figure 6-1. If the single SCSI controller board is used to control internal SCSI drives (SCSI model), it will be early in the boot order. The single SCSI controller board has two SCSI connectors, but only one SCSI connector can be active at a time. The Server scans the active SCSI connector for a boot device starting at device ID 0 and works up from there. 46

Accessory Board Installation Guidelines
The following sections provide the guidelines necessary to install the PCI
accessory boards into the Server.
NOTE
Some full-length PCI boards may need a plastic "handle"
(board extension) on one end to stabilize the board in the
Server. If the board requires one and it is not installed, you
may need to install the handle on the board, before installing it
in the HP Server. See Figure 6-5.
IRQ Settings
The IRQ settings are automatically assigned and don't require user intervention.
The HP Server uses the Plug-and-Play feature of the PCI boards to correctly assign
its resources automatically.
Installing a Disk Array Controller Board
Adding a disk array controller board provides additional fault tolerance to your
internal or external mass storage devices. If you plan on adding a disk array
controller board to the HP Server tc2100, HP recommends installing the HP
NetRAID-1M PCI board in slot 1 or 2 depending on the Server model (IDE or
SCSI). When installing a disk array controller board, you may alter the Server's
boot order to allow the Server to boot off one of the array's drives. This boot order
can be changed under the
Boot
menu of the Server's (BIOS) Setup Utility.
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 accessory board's boot priority is set by its slot location in the boot
order. See Figure 6-1.
If the single SCSI controller board is used to control internal SCSI drives (SCSI
model), it will be early in the boot order. The single SCSI controller board has two
SCSI connectors, but only one SCSI connector can be active at a time. The Server
scans the active SCSI connector for a boot device starting at device ID 0 and
works up from there.
