Cabling Requirements

A 16-bit (wide) SCSI cable connects each hot-swap backplane to an integrated SCSI-2 controller on the system board; and an 8-bit SCSI cable connects the CD-ROM drive to the 8-bit connector on the top backplane. The 8-bit cable connected to the CD-ROM drive has two empty connectors that you can use to support additional 8-bit SCSI devices in the upper-left front bays.

If you plan to install external SCSI devices, you must order an additional SCSI cable and a SCSI-2 adapter. That is, to use external devices, you must connect them to an optional SCSI-2 adapter, using a SCSI cable.

Each SCSI-2 integrated controller can support a total of 14 devices, provided that you do not exceed the maximum cable lengths. Refer to your RAID adapter documentation to determine the number of internal and external connectors, channels, and SCSI devices that your RAID adapter supports.

If you are using a SCSI data transfer rate greater than 5 MB per second, the maximum length of the SCSI bus (cable) must not exceed 3 meters (9.8 feet). If you are using a SCSI data transfer rate of 5 MB per second or slower, the maximum length of the SCSI bus cable must not exceed 6 meters (19.7 feet). These lengths apply to the combined lengths of the internal and external cables. Adhering to these standards ensures that your server operates properly.

Before you install external SCSI devices, you must have the correct external SCSI cables. The cables must have the proper connector for the SCSI-2 adapter on one end, and the proper connector for the first external device on the other end. To select and order the correct cables for use with external devices, contact your IBM reseller or IBM marketing representative.
