SCSI Cabling Requirements
The following are the SCSI cabling requirements that must be considered before connecting SCSI cables to
the disk array:
1.
The external bus connected to the disk array must be a SCSI-2 wide differential device cable with 68-
pin high-density external SCSI connectors.
2.
Each SCSI bus must be terminated with a passive differential SCSI terminator on the last device.
Therefore, for dual controller disk array configurations, you will need two passive differential
terminators, one for each bus.
3.
Each disk array contains an equivalent of 0.5 meters of internal SCSI cabling per bus.
4.
The total combined length of internal SCSI cabling plus external SCSI cabling must not exceed 25
meters.
Connecting SCSI Cabling
NOTE! Before connecting SCSI cables, press the power/standby switch to the standby (out)
position. It may take a moment for the disk array to fully shut down.
SCSI cables are available in standard lengths. Each controller must have a different SCSI ID,
even when using dual controller configurations. To change controller SCSI IDs, refer to the
chapter titled, "Operating the Control Panel."
