Hard Drive Backplane
The SATA/SCSI drives plug into a backplane that provides power, drive ID and
bus termination. A RAID controller can be used with the backplane to provide data
security. The operating system you use must have RAID support to enable the hot-
swap capability of the Serial ATA drives. The backplane is already preconfi gured,
so there are no jumpers or switches present on it.
DVD-ROM and Floppy Drive Installation
The top cover of the chassis must be opened to gain full access to the DVD-ROM
and fl oppy drive bays. The 6025B-TR+/6025B-8R+ accomodates only slim type
DVD-ROM drives. Side mounting brakets are typically needed to mount a slim
DVD-ROM drive in the 6025B-TR+/6025B-8R+ 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 fl oppy
or IDE components.
Drives mount on rails and should "click" into place to be correctly and fully installed
in their bays.
• The fl oppy disk drive cable has seven twisted wires.
• A color mark on a cable typically designates the location of pin 1.
• A single fl oppy disk drive ribbon cable has 34 wires and two connectors to provide
for two fl oppy 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.
