Video port
Your server comes with an integrated super video graphics array (SVGA) video
controller. This controller is not removable, but you can disable it by installing a
PCI video adapter.
Note: If you install a PCI video adapter, the server BIOS will automatically disable
the integrated video controller.
The following table shows the pin-number assignments for the 15-pin analog video
connector on the rear of your server.

SCSI ports
Your server has an integrated dual-channel Ultra3 small computer system interface
(SCSI) controller. This controller supports two independent Ultra 160/m SCSI
channels, both internal. Each of these channels supports up to 15 SCSI devices. In
addition, this controller uses:
v
Double-transition clocking to achieve high transfer rates
v
Domain name validation to negotiate compatible data transfer speeds with each
device
v
Cyclic-redundancy checking (CRC), instead of the usual parity checking, to
significantly improve data reliability
v An active terminator on the system board for SCSI bus termination
A SCSI cable connects the SCSI channel A connector to the hot-swap drive
backplane. If you obtain an additional SCSI cable, the SCSI channel B connector is
available for connecting non-hot-swap SCSI drives in the 5.25-in. bays.
If you install a SCSI adapter in your server, you can use its SCSI connector to
connect different types of small computer system interface (SCSI) devices.
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 SCSI
connector to an internal channel connector on the RAID adapter.
