Keyboard port
There is one keyboard connector on the rear of your server.
Note:
If you attach a standard (non-USB) keyboard to the keyboard connector, the
USB ports and devices will be disabled during the power-on self-test
(POST).
The following illustration shows the keyboard connector on the rear of your server.
This connector conforms to the industry standard for a PS/2
®
keyboard.

Ultra320 SCSI system-board connectors
Your server has an integrated dual-channel Ultra320 small computer system
interface (SCSI) controller. This controller supports two independent, internal
Ultra320 SCSI channels. The SCSI channel connectors are on the system board.
Each channel supports up to 15 SCSI devices. This controller uses:
v
Double-transition clocking to achieve up to 320 MB-per-second data-transfer
rates
v
Domain validation to negotiate compatible data-transfer speeds with each device
v
Parity checking to ensure data reliability
v
An active terminator for SCSI bus termination
The server comes with one SCSI cable that is connected from the internal SCSI
channel A connector to the standard hot-swap-drive backplane. You can attach
additional internal SCSI devices to the other internal SCSI channel B connector, or
you can use channel B for external SCSI devices. To use channel B for external
SCSI devices, remove the external SCSI knockout from the rear of the server (see
“Cabling the server” on page 68 for external SCSI knockout location) and secure
the free end of an optional channel B cable in the new opening.
If you want to attach external SCSI devices to the server without using the internal
SCSI channel B, you must install an optional SCSI adapter.
Note:
If you install a PCI RAID adapter to configure and manage the internal
hot-swap drives, you must move the SCSI cable from the system-board
