Additional Precautions
Observe the following precautions when connecting SCSI cables to the CDA 7
SCSI channel interface connectors:
• Use the shortest cabling possible between the CDA 7 unit and the host.
• Always check for bent pins on the SCSI cables before connecting them. The
SCSI cable pins bend very easily.
• Always attach SCSI cables to their connectors straight on to minimize the
chance of bending pins.
• The pin shroud on the SCSI cable ends deforms easily. Take care not to drop
cable ends or bang them against objects.
• When attaching the SCSI cable to the connector on the SCSI adapter in the CDA
unit, remember to fasten the screws on the connector to ensure a secure
connection.
• When connecting to hosts with differential Fast-Wide SCSI interfaces, do not
allow the cable length to exceed 82 feet (25 m).
• When connecting to hosts with Ultra SCSI interfaces, do not allow the cable
length to exceed 62 feet (19 m).
• Fibre Channel interfaces extend connectivity up to a maximum of 1600 feet (500
meters).
