Apple Workgroup Server 8550 - Manual (Page 69)

Connecting an external SCSI device
To connect a SCSI device to the port on your server’s back panel:
1 Make sure that the server and SCSI device are turned off.
2 Check that the device has its own, unique ID number between 0 and 6.
See the section “Setting the SCSI ID Number” earlier in this chapter
for details.
3 Use a SCSI cable to connect the device either to the server’s SCSI port or to the last
SCSI device already in the chain.
If the device is the first or only one you’re connecting, use a SCSI system
cable to connect it to the server’s SCSI port.
If the device is not the first one, use a SCSI peripheral interface cable to
connect it to the last device in the chain.
IMPORTANT To get the best results with SCSI devices, be sure to use high-
quality SCSI cables and check that the total length of the cables in a SCSI
chain does not exceed 6 meters (20 feet). Use SCSI cables manufactured by
Apple Computer or those of similar quality.
WARNING Do not connect or disconnect any device while the device or
your server is turned on. Doing so could damage the device, your
server, or both.
