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 CD-ROM drive must be one with a "slim"
profile to fit into the 6011L.
First, release the retention screws that secure the 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
drives.
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 red 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.
