SCSI Controller Board
SCSI controller board (N8103-56F/65F/75F) is a PCI board to control hard disk drives and file
devices that operate through the SCSI interface.
The SCSI controller board is necessary in the following cases:
 Installing a file device in the 5.25-inch device bay of the server
 Using a SCSI hard disk as an internal hard disk
 Connecting external SCSI equipment.
Notes
The following explains notes on using the SCSI controller board:
 The SCSI controller board is an electronic component easily affected by static electricity.
Before handling the SCSI controller board, discharge static electricity from your body by
touching the metal frame of the server or the like. Do not touch the terminals or parts of
the SCSI controller board with your bare hands, or do not place the SCSI controller board
directly on a desk. See "Static Precautions" for details on static electricity.
 When connecting hard disks containing an OS to the SCSI controller board, install them
in the PCI slots in ascending order of the slot numbers.
 See "PCI Board" described earlier in this chapter for slots in which boards can be
installed.
