Video Connector; Ultra160 Scsi Connector (Some Models); Scsi Cabling Requirements - IBM xSeries 200 Hardware Maintenance Manual

Video connector

The server uses an AGP video adapter located in the AGP slot on the system
board. There is a 15-pin analog video connector located on the rear of the server.
See "I/O connector locations" on page 64 for the location of this connector. The
following table shows the pin-number assignments for the video connector.

Ultra160 SCSI connector (some models)

Some xSeries 200 server models come with a SCSI adapter, which supports a single
Ultra160 SCSI channel in a full-featured PCI 2.1-/2.2-compliant bus master
package. This configuration supports a zero wait state, 32-bit memory transfers at
160 MB per second, when low voltage differential (LVD) SCSI peripherals are
attached. This channel supports up to 15 SCSI devices. In addition, the SCSI
adapter uses:
v Double-transition clocking to achieve high transfer rates
v Domain name validation to negotiate compatible data transfer speeds with each
v Cyclic-redundancy checking, instead of the usual parity checking, to significantly
Note: If you install a RAID adapter, you can move the SCSI signal cable from the

SCSI cabling requirements

You can install five internal SCSI devices using the SCSI signal cable that comes
with the server or purchased separately, depending on the server model. If you
