5.4 Installing External Storage Devices
5.4 Installing External Storage Devices
1. Determine what external storage devices you have:
• BA42 expansion box
• TCE, if it has internal drives
• Self-contained tape, disk, or compact disc drive
2. Check to make sure that the number of SCSI drives and storage expansion
boxes to be connected are within the allowable limits. You can connect up
to seven SCSI drives, contained in up to three expansion boxes, to the base
system SCSI connector.
3. Make sure that each SCSI drive on the same bus has a unique SCSI ID
number. If two or more of the drives to be connected to a SCSI connector
have the same SCSI ID number, you must change the duplicate SCSI IDs
(see Section 5.6).
4. Position the storage expansion boxes next to or on top of the system unit.
If one of the boxes is a TCE, place it directly on top of the system unit,
because one of its interconnecting cables is very short. You may stack the
boxes one on top of the other.
5. Set the power switches on the storage expansion boxes to the off position.
(Figure 5–2).
