SCA Backplane
The SCSI drives plug into a SAF-TE compliant 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; there are 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 6012P-6 accomodates only slim-line CD-
ROM drives. Side mounting brakets are needed to mount a slim-line CD-ROM
drive in the 6012P-6 server.
You must power down the system before installing or removing a floppy
or CD-ROM drive. 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.
With the chassis cover removed, unplug the power and data cables from
the drive you want to remove. Then locate the locking tab at the rear of
the drive. It will be on the left side of the drive when viewed from the
front of the chassis. Pull the tab away from the drive and push the drive
unit out the front of the chassis. Add a new drive by following this
procedure in reverse order. You may hear a faint *click* of the locking
tab when the drive is fully inserted. Remember to reconnect the data and
power cables to the drive before replacing the chassis cover and
restoring power to the system. Please be aware of the following:
• 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. (You can only install one
internal floppy drive into the 6012P-6.)
