Quick Start Setup Guide

Introduction

The RACKMUX-T15 (RACKMUX) is a general-purpose character terminal with a 15" color LCD display and keyboard mounted in
a 1U high rack mountable tray. The RACKMUX connects to servers using either a serial RS232 console connection or an Ethernet
telnet RSC console connection (to the RSC Ethernet console port where available). The terminal offers multiple personalities, and
can connect to multiple servers when used with a Console Server (for RS232 connections) or with an Ethernet Switch (for
Ethernet connections). This guide describes the basic installations and configuration procedur e. For further details, please see
the RACKMUX-TERMINAL Installation and Operation Manual.

Hardware Installation

Hardware installation consists of the following steps:

1. Determine the mounting height in the rack for the drawer. It should be a height comfortable to use the keyboard and see the
LCD display. Mark holes in each of the 4 corner cabinet rails at points all level with each other.

2. Secure the rear brackets to the rear rack cabinet rails at the holes marked in step 1 using #10-32x3/4” screws and cage nuts
(supplied). Be sure to tighten the screws securely.

3. Lift the keyboard into position and line the studs on the left and right sides up with the slotted openings in the rear br acket.
Apply the nuts (supplied) to the studs but do not tighten the nuts yet.

FYI: There are 5 mounting studs provided on each side of the RACKMUX. Depending on the depth of the rack and
distance apart of the cabinet rails, the position of the rear bracket may make all 5 studs available for use. In this case,
apply the 2 nuts to the studs furthest apart from each other on each side.

4. Slide the drawer in until the top holes in the front bracket flanges line up with the holes marked in step 1. Secure the front
brackets on the drawer to the front cabinet rails using #10-32x3/4” screws and cage nuts (supplied). Be sure to tighten the
screws securely. Then tighten the nuts applied in step 3.

Note: Very deep racks may require the back of the rails to be bolted to an internal mid-rail within th e rack, in which
case the rear rail extensions should be reversed so as to present the appropriate mounting holes to the rack mid­rails.

Cable Connections

The terminal may be configured to communicate using either a serial RS232 connection or an Ethernet telnet connecti on.
Although it is possible to connect both RS232 and Ethernet cables, it is only possible to use one type of connection at any time
(determined by the configuration defined in terminal set up). The Ethernet network connection may be u s ed to connect to any
10Mb compatible Ethernet host adapter. However the Ethernet connection is most suited for use with RSC (Remote System
Control) Ethernet ports since these provide the same functionality as serial (ttya) console ports.

If connecting a serial RS232 cable to the server, it is advisable to power down the server first.

The rear of the terminal tray has the following connections.

IEC POWER

CONNECTOR

• VGA and MONITOR

These two 15HD female video ports must be joined together using the VEXT-1,5-MM cable supplied. Connect this cable
between these ports.

• Serial 2 and Parallel

The terminal supports a local printer that can be connected to a serial (male 9-pin D connector) or parall el (femal e 25-pin D
connector) interface. Printer cables are not included with the terminal, and specific printers have not been qualified for this
connection.

• Serial 1

This is a male 9-pin D connector port that should be used for a serial RS232 console connectio n. T he included 9DB female to
25DB male null modem cable can be used to connect this port to a female 25-pin D connector console port. A 25-pin to 9-pin
adapter will be needed (not included) in conjunction with this cable when connecting to a male 9-pin D connector console port.

If connecting to a SUN server, when the terminal loses power or is powered OFF, a ‘break’ may be generated on the RS232
(SERIAL 1) CPU port (as is common with most general purpose terminals). To prevent this halting a connected Sun server,
ensure that the “alternate break” sequence is configured. See SunSolve Info Doc 21258 for details.

If connecting the terminal using the RS232 connection to a Console Server, use cabling recommended by the Console Server
manufacturer. In this case an alternate break sequence may not be required, since some console servers are “Break Safe”. Refer
to the Console Server documentation for details.

• 10Base T

This is an RJ45 port that may be used for an Ethernet server connection. This connection may be used with any 10Mb compatible
Ethernet host adapter. However the Ethernet connection is most suited for use with the RSC (Remote System Control) Ethernet
ports since these provide the same functionality as serial (ttya) console ports.

Connect an RJ45-to-RJ45 UTP cable (not supplied) between this port and an Ethernet 10Mb compatible hub or switch. The
network hub/switch should in turn be connected to the server RSC Ethernet port(s). The terminal supports 12 concurrent telnet
connections when configured in Econ-80 screen column mode. The number of concurrent telnet connections reduces to 8 when
using standard 80 column mode.

Note: It is advisable that this network remains a private network for security reasons. If only one server is to be
connected to by the terminal, a crossover (or cascade) UTP cable may be used .

When using an Ethernet console connection, the alternate break sequence need not be defined. However, the RSC Ethernet port
must be configured using the “rsc-config” command.

Finally, connect the powercord to the IEC connector.
