Chapter 6: Advanced Chassis Setup

SCSI Power Cables
SCSI power cables should be routed so that they do not block the airflow
through the chassis. There is a 4-pin connector for the power cables.
SCA Backplane
The SCSI drives plug into an SCA backplane that provides power, SCSI ID
and bus termination. A RAID controller can be used with the SCA backplane
to provide data security. The operating system you use must have RAID
support to enable the hot-swap capability of the SCSI drive. The SCA SCSI
backplane is already preconfigured, so it has no jumpers or switches.
CD-ROM and Floppy Drive Installation
The top cover of the chassis must be opened to gain full access to the CD-
ROM and floppy drive bays. The 6021F accomodates only slim-line 5.25-
inch CD-ROM drives. Side mounting brakets are typically needed to mount a
slim-line CD-ROM drive in a 6021F server.
First, release the retention screws that secure the server unit to the
rack. Grasp the two handles on either side and pull the unit straight out
until it locks (you will hear a "click"). Next, depress the two buttons on
the top of the chassis to release the top cover and at the same time,
push the cover away from you until it stops. You can then lift the top
cover from the chassis to gain full access to the inside of the server.
You must power down the system before installing or removing floppy or
IDE components.
Drives mount on rails and should "click" into place to be correctly and
fully installed in their bays.
• The floppy disk drive cable has seven twisted wires.
• A color mark on a cable typically designates the location of pin 1.
• A single floppy disk drive ribbon cable has 34 wires and two connectors to
provide for two floppy disk drives. The connector with twisted wires always
connects to drive A, and the connector that does not have twisted wires
always connects to drive B.
