SCSI Terminal Server
Hardware Installation
Guide
Introduction
The SCSI Terminal Servers provide from two to 32 local serial ports that
require no complex network overhead. The ports, which are simple to
install and configure, attach externally to the SCSI bus of a UNIX or
Windows NT system. The EIA 232 ports can be used for connecting
devices such as terminals, modems, and printers.
Installing the SCSI Terminal Server Software
Note: It is best to install the software driver before installing the hardware because a SCSI ID number must be determined before installation
of the SCSI Terminal Server.
To install the software, follow the installation directions found with the
Access Resource CD-ROM.
Installing the SCSI Terminal Server
Caution: The host machine, all of its SCSI peripherals, and any other
devices that are be connected to the Digi SCSI Terminal Server must be
turned off before installation. Failure to do so may result in damage to the
system and its peripherals.
Use the following procedure to install the Digi SCSI Terminal Server on
your network.
1. Attach the SCSI Terminal Server to the SCSI bus using the cables
included in the package.
2. Push the active termination switch (#1) up if the SCSI Terminal
Server is the last device on the SCSI bus. The switch must be down
if it is not the end device on the SCSI bus.
Note: The associated LED will be on if the switch is up and termination power is available on the SCSI bus.
3. Set the appropriate device ID as determined during the software
installation process by properly setting SCSI ID switches 2 to 4.
Note: You must use a unique number for each SCSI device on the
SCSI bus. Changes made to the SCSI ID switches will only be recognized when the unit is powered up.

4. Attach the cables from the peripheral devices to the SCSI Terminal
Server.
5. Connect the power supply and/or power cord to an AC outlet.
6. Power up the network server and its peripherals.
7. Check to see that the SCSI Terminal Server is operating correctly.
Note: See the Troubleshooting section below for common installation problems.
Rack Mount Installation
For the SCSI Terminal Server 1032, a rack mount kit is included. The
rack mount brackets may be installed at either the front or rear of the unit.
To install each bracket, do the following:
1. Remove the two screws on the side of the cabinet.
CAUTION: To prevent electric shock, do not remove the module
cover. There are no user-serviceable parts inside. Refer
servicing to qualified personnel only.
2. Align the holes of the bracket with the vacated holes in the cabinet.
Use the screws to fasten the bracket to the cabinet.
Rack Mount Considerations
When doing a rack mount installation consider the following:
• Cumulative power requirements of the unit and other equipment
installed in the rack. Do not overload rack supply circuits.
• Safety and stability. Always stack the rack from bottom up to ensure
a stable and safe rack.
• Air flow in the rack. Make sure the unit’s ambient temperature does
not exceed 95°F (35°C).
• Grounding. Earth ground the unit reliably to the rack system. The
earth ground connection must be maintained when the supply connection is other than a direct connection to the branch circuit.
EIA - 232 Connectors
Many EIA-232 serial devices implement their serial ports with DB-25
connectors. The SCSI Terminal Server units have serial ports implemented with 8-pin RJ-45 modular jacks, with each signal using EIA-232
voltage levels. The figures below shows the pinouts of all these connector
types
Note: The SCSI Terminal Server RJ-45 pin configuration is different
from the configuration of the RJ-45 connectors used on other Digi products. RJ-45 cables designed for other Digi products must not be used
with Digi SCSI Terminal Server.

Troubleshooting
If the SCSI Terminal Server does not operate properly, check the list
below for some common installation problems
.
• The most frequent problem is duplicate SCSI ID numbers. The SCSI
adapter card is usually set to #7. Make sure the SCSI Terminal
Server module ID number is not conflicting with that number.
• Check the cable to see that it is properly inserted and is completely
seated. The pins in the SCSI cable are delicate and can be easily bent
if not inserted carefully. It might be necessary to disconnect the cable
to inspect for bent pins.
• Inspect the power cord to verify it is inserted completely and the
power is turned on.
