Paralan SS1

MODEL SS1 - 2 x 1 SCSI Switch for Rack Mount or Tabletop

Highlights:

The SS1 SCSI Bus Switch allows two hosts to share peripherals or one host to access either of two sets of peripherals. Each port may be SE, HVD or LVD. Switching from one port to the other may be accomplished: a. locally with the front panel switch, b. remotely with a momentary dry contact closure, or c. remotely via the RS-232 port. In mode One, Port 1 is connected to the Common Port. In mode Two, Port 2 is connected to the Common Port. A front panel LED displays the selected port. Each port supports a full SCSI cable length and provides term power and termination, which may be disabled. The SS1 does not consume a SCSI device ID, is transparent to both initiator and target, and does not slow data throughput. Devices on the LVD ports run at SCSI throughput up to 160 Mbytes/sec, HVD and SE ports run at up to 40 Mbytes/sec. An amber LED for each port indicates bus activity and a green LED indicates that each port is powered. See Rear View Photo. A front panel 7-segment LED display shows the active port.

Specifications:

The Model SSI SCSI Switch allows three independent SCSI Buses to be connected in several configurations as delineated in the table below:

ORDERING GUIDE FOR SCSI SWITCH, Standard Configurations:

SCSI 2 X 1 Switch For Tabletop or Rack

Example 1: Model No. SS1-LHL-T - Tabletop Model SS1 with LVD/MSE at both switched ports and HVD at the Common port

Example 2: Model No. SS1-SLH-R - Rack Mount Model SS1 with LVD/MSE at the Common port, SE Wide at Port 1 and HVD at Port 2

Notes:

• The SS1 comes assembled and wired with the selected Ports installed.
• A six foot (1.84 m) North American grounded cordset (NEMA 5-15, rated 250 VAC) is included in shipments to destinations in North America and Japan. Other destinations receive no cordset.
