Upgrading Your Server 9-25
There are three types of PCI boards: 5V PCI boards, 3.3V PCI boards, and universal PCI boards.
A 5V PCI board must be installed in the 5V PCI slot, and a 3.3V PCI board must be installed in the
3.3V PCI slot. A universal PCI board can be installed in any PCI slot.

RAID Controller Considerations
Note the following on the configuration of a disk array.
To change the disk array configuration or the RAID, the hard disks must be initialized.
If important data is saved in the hard disks used to constitute a disk array, first back up the
data in other hard disks before installing boards and configuring the disk array.
More than one hard disk is required to configure a disk array.
Hard disks used in the disk array configuration should have the same disk revolution rate
and capacity in packs.
See table in the next page for the slot in which a board can be installed.
Up to four disk array controller boards can be installed in the server.
Several RAID (Redundant Arrays of Inexpensive [Independent] Disks) levels can be set
for the disk array configuration in the server in which disk array controller boards are
installed. Refer to the documentation coming with the disk array controller for details of
the available RAIDs, data transfer rate, and array configuration.
The available capacity of the hard disks in the disk array configuration is lower than the
total capacity of the hard disks configuring the disk array while the disk reliability is
improved (for RAID 1, 5, or 0+1).
Set "Option ROM Scan," a parameter of the slot in which a hard disk is installed, to
"Enable" in "PCI Configuration" on the Advanced menu of the BIOS utility SETUP.
Replacement of disk array controller board
Back up the disk array configuration information in the disk array controller board to the
floppy disk and restore it to the replaced disk array controller board. Use the
configuration utility for the restoration. Refer to the manual that comes with the disk
array controller for details. If a disk array controller is replaced, create the configuration
information newly by using the proper utility.
When more than one disk array controller board are installed in the server, install the disk
array controller board to which the system disk is connected in the PCI slot having the
highest boot priority (from PCI #1 to #8). For example, if four disk array controller
boards are installed in PCI slots #3 to #6, the system disk should be connected to the
board installed in PCI slot #3.
Standard Network
An AFT/ALB teaming is unavailable in standard network (between onboard controllers).
An AFT/ALB teaming with standard network and an option LAN board is also
unavailable.
