SUPER MICRO Computer 6012L-6 user manual CD-ROM and Floppy Drive Installation, SCA Backplane

Chapter 6: Advanced Chassis Setup

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 6012L-6 accomodates only slim-line CD- ROM drives. Side mounting brakets are needed to mount a slim-line CD-ROM drive in the 6012L-6 server.

You must power down the system before installing or removing a floppy or CD-ROM drive. Then, 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 thorugh 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 6012L-6.)
