I/O Modules

The Adaptec U320 SCSI midplane has two I/O module connectors
on the rear of the midplane. The I/O modules connect to the two
SCSI buses. There is also a connector for the Enclosure Services (ES)
module.
The ES module monitors and controls cooling and supports
■
in-band environmental reporting.
The IO module contains the external (dual port) SCSI VHDCI
■
connectors.
The Joiner module connects the two SCSI buses into a single
■
SCSI bus with SCSI IDs 0 to 5 and 8 to 13. Without the Joiner
module, the backplane is a dual-bus backplane with each bus
having SCSI IDs 0 to 5.
