• For a list of supported options for your server, go to http://www.ibm.com/pc/compat/ on the World Wide Web. Preinstallation steps (all bays) Before you install drives in your server, verify that you have all the cables and any other equipment specified in the documentation that comes with the drive. You might also need to perform certain preinstallation activities. Some of the steps are required only during the initial installation of an option. 1. Read "Safety" on page v, "Handling static-sensitive devices" on page 6, and the documentation that comes with your drive. 2. Choose the bay in which you want to install the drive. 3. Check the instructions that come with the drive to see if you need to set any switches or jumpers on the drive. Power and signal cables for internal drives Your server uses cables to connect IDE devices to the power supply and to the system board. The following cables are provided: • Four-wire power cables connect the drives to the power supply. At the end of these cables are plastic connectors that can be attached to different drives; these connectors vary in size. Also, certain power cables are attached to the system board. • Flat signal cables, also called ribbon cables, connect IDE and diskette drives to the system board. There are two sizes of ribbon cables that come with your server: - The wider IDE signal cable has two or three connectors. - If the cable has three connectors, one of these connectors is attached to the drive, one is a spare, and the third is attached to the primary or secondary IDE connector on the system board. - If the cable has two connectors, one of these connectors is attached to the hard disk drive, and the other is attached to the primary or secondary IDE connector on the system board. Note: The CD-ROM drive is attached to an ATA 66 signal cable. The hard disk drive is attached to an ATA 100 signal cable. ATA 66 and ATA 100 signal cables are color-coded. The blue connector attaches to the system board. The black connector attaches to the primary device. If the cable has a gray middle connector, it attaches to the secondary device. If you are installing a hard disk drive, you must change the switch setting on the CD-ROM drive to secondary and change the connector used for the CD-ROM drive to the gray middle connector. - The narrower signal cable has two connectors, one to attach to the diskette drive, and the other to attach to the connector (FDD1) on the system board. • SCSI signal cables connect SCSI devices to a SCSI adapter or to the internal SCSI connector on the extender card (some models). If you have a SCSI adapter installed in your server, the SCSI signal cable has four connectors. One connector is attached to the SCSI connector on the extender card, two connectors are spares, and the fourth connector is attached to a SCSI hard disk drive. To locate connectors on the system board, see "System-board internal cable connectors" on page 4. Chapter 2. Installing options 15

For a list of supported options for your server, go to

http://www.ibm.com/pc/compat/ on the World Wide Web.

Preinstallation steps (all bays)

Before you install drives in your server, verify that you have all the cables and any

other equipment specified in the documentation that comes with the drive.

You might

also need to perform certain preinstallation activities.

Some of the steps are required

only during the initial installation of an option.

Read “Safety” on page v, “Handling static-sensitive devices” on page 6, and the

documentation that comes with your drive.

Choose the bay in which you want to install the drive.

Check the instructions that come with the drive to see if you need to set any

switches or jumpers on the drive.

Power and signal cables for internal drives

Your server uses cables to connect IDE devices to the power supply and to the system

board.

The following cables are provided:

•

Four-wire power cables connect the drives to the power supply.

At the end of

these cables are plastic connectors that can be attached to different drives; these

connectors vary in size.

Also, certain power cables are attached to the system

board.

•

Flat signal cables, also called ribbon cables, connect IDE and diskette drives to

the system board.

There are two sizes of ribbon cables that come with your

server:

—

The wider IDE signal cable has two or three connectors.

–

If the cable has three connectors, one of these connectors is attached to

the drive, one is a spare, and the third is attached to the primary or

secondary IDE connector on the system board.

–

If the cable has two connectors, one of these connectors is attached to

the hard disk drive, and the other is attached to the primary or secondary

IDE connector on the system board.

Note:

The CD-ROM drive is attached to an ATA 66 signal cable.

The hard

disk drive is attached to an ATA 100 signal cable.

ATA 66 and ATA 100

signal cables are color-coded.

The blue connector attaches to the

system board.

The black connector attaches to the primary device.

the cable has a gray middle connector, it attaches to the secondary

device.

If you are installing a hard disk drive, you must change the

switch setting on the CD-ROM drive to secondary and change the

connector used for the CD-ROM drive to the gray middle connector.

—

The narrower signal cable has two connectors, one to attach to the diskette

drive, and the other to attach to the connector (FDD1) on the system board.

SCSI signal cables connect SCSI devices to a SCSI adapter or to the internal

SCSI connector on the extender card (some models).

If you have a SCSI adapter

installed in your server, the SCSI signal cable has four connectors.

One

connector is attached to the SCSI connector on the extender card, two connectors

are spares, and the fourth connector is attached to a SCSI hard disk drive.

To locate connectors on the system board, see “System-board internal cable

connectors” on page 4.
