Connecting hard disks and other SCSI devices

Your Workgroup Server 8550 has two buses for connecting devices that use the Small Computer System Interface (SCSI, pronounced “skuh-zee”). The SCSI connections permit high-speed communication between the server and the devices. SCSI devices commonly attached to the Workgroup Server 8550 include hard disks, CD-ROM drives, scanners, printers, and tape-backup drives.

IMPORTANT Before connecting a device to your server, be sure that the server (and any other device already connected to it) is turned off. Read the instructions in this section and the instructions that came with your hard disk or other SCSI device before connecting it to your server.

Bus A is the internal Fast SCSI-2 bus (10 MB per second) that connects your server’s CPU to the built-in disk drive in the bottom bay of the internal disk drive bracket. Additional devices cannot be connected to the internal SCSI bus (unless the cabling for this bus is modified by an Apple-authorized service provider).

Bus B is an internal/external SCSI-1 bus (5 MB per second) to which a total of seven devices can be connected. The CD-ROM drive that is built into your server is connected to the internal/external SCSI bus. The optional internal hard disk (which can be installed in the top bay of the internal disk drive bracket) and the optional built-in DAT drive (or any other drive in your server’s auxiliary bay) are also connected to this internal/external SCSI bus when installed. Your server has a port for connecting additional external SCSI devices to the internal/external SCSI bus. The SCSI icon appears above the port on the server’s back panel.

You can connect SCSI devices to the SCSI port in a chain. The first device in the chain plugs into the SCSI port; the second device plugs into the first device, and so on. If the only device connected to your server’s internal/external SCSI bus is its built-in CD-ROM drive, you can attach up to six external SCSI devices. However, if you have a built-in DAT drive and a second internal hard disk connected to this SCSI bus, you can attach only four external SCSI devices to the port.
