Installation
Ultra Wide SCSI Mode
24
Single-Bus Enclosure
With the Single-Bus module is installed, all of the disk drives in the CR8e
enclosure are on the same SCSI bus. With this configuration you will have a total
storage capacity of up to 145 GB (using 18 GB disk drives) per subsystem
enclosure and have access to the drives independently or as a single large array.
The SCSI IDs of the drives are set by SAF-TE card defaults to IDs 0 through 9,
and are assigned sequentially beginning with the lowest or far right drive.
NOTE: SCSI ID 3 is reserved for the SAF-TE card processor and ID 7 reserved
for the RAID controller.
CAUTION: Ensure that the power switch is in the OFF (O) position for both the
host system and the CR8e subsystem before connecting any cables.
1Connect one end of a one meter data cable to the Channel #1 connector on
the AM RAID Controller.
2Connect the other end of the data cable to the Channel #1 SCSI connector on
the upper or right side I/O Interface card.
NOTE: The Channel #1 connector located on the upper or right side I/O Interface
card is the active connector when the Single-Bus module is installed.
NOTE: SCSI termination is automatic and requires no user configuration. Refer
to “Termination” on page 21 for information on systems using DEC
Fault bus protocol.
