Hard Drive Backplane
The SATA drives plug into a backplane that provides power, drive ID and bus termi-
nation. 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 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 2021M-UR+ accomodates only slim type DVD-ROM
drives. Side mounting brakets are typically needed to mount a slim DVD-ROM
drive in the 2021M-UR+ server.
First, 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 without twisted wires always connects to drive B.
