Chapter 1: About the Gateway 850 SCSI Storage Enclosure

www.gateway.com

The SAF-TE Disk I/O card has two 68-pin VHD/CI SCSI connectors which
provide the connectivity from the host computer(s) to the drives. The
connectors are labeled “Channel 1” and “Channel 2.”

In JBOD single-bus mode, the Channel 1 connector provides SCSI bus access
to all the drive slots, 1 through 12, and the Channel 2 connector provides the
automatic SCSI bus termination.

In JBOD Dual-Bus mode, the Channel 1 connector provides SCSI bus access to
the drives in slots 7 through 12, and the Channel 2 connector provides access
to the drives in slots 1 through 6. Termination is automatic and provided
internally on the drive mid-plane circuit board.

RS-232 ports

The SAF-TE Service RS-232 serial port is located below the I/O card slots, and
between the two Control ports. The SAF-TE Service port provides an RS-232
serial interface to the SAF-TE Disk I/O card allowing firmware uploads and
maintenance/service monitoring of the SEPs.
