Quick Start Setup Guide

Introduction

The RACKMUX® Terminal Drawer with Secure SSH Console Switch combines a Terminal Drawer and an integrated SSH
Console Switch delivering secure management of up to 32 serial devices via the Internet, TCP/IP network, or dial-up modem
connections in only 1RU of space.

The main purpose of the Console Switch is to provide secure management of several serial devices from local or remote locations
(using Ethernet or external modems). Devices include routers, DSU's, servers, switches or any other equipment allowing serial
operation using RS232 interface. Users can work locally using the integrated Terminal Drawer or from remote locations via
Ethernet connection (Web Interface, SSH, Telnet).

Each SERIMUX port has to be configured for serial communication (baud rate, parity, etc) within the specifications of the attached
serial device, but the configurations of the two devices linked by the SERIMUX do not need to match. Various parameters
(communication speed, hardware and/or software flow control, timeout, etc) can be selected for each SERIMUX port. Devices
may be either locally connected or connected through attached modems.

Each SERIMUX port can be configured as either a host or user port. Serial hosts (such as servers, switches etc.) are connected to
host ports, while serial user devices (such as a terminal or serial console) are connected to user ports.

This guide describes the basic installation and configuration procedure. For further details, please see the SERIMUX-S-x
Installation and Operation Manual (go to

http://www.networktechinc.com/pdf/man107.pdf).

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

1. Connect each serial user device or host device to be connected by the SERIMUX to any serial port (1-4/8/16/24/32) using a
serial cable with an RJ45 male connector (image below). It may be necessary to add one of the cable adapters (supplied)
detailed in Appendix C of the manual between the device port on the user device or host device and the RJ45 connector.

2. Connect the power cord to the IEC connector.

3. Connect the Console Switch to the Ethernet for remote system management using the “ETHERNET1” or “ETHERNET 2” port
and CAT5/5e/6 patch cable.

Configuration

The terminal is delivered pre-configured. For your reference, this section describes configuration for connection to the integrated
Console Switch.

• Switch ON the terminal using the power switch located at the rear of the keyboard.

• Hold down the <ALT> key and then depress the <Esc> key to enter Setup Mode.

• Adjust the screen's brightness and image position as described under “Displa y Functions” on page 5.

• To navigate the setup menus, use a function key to enter a setup menu, and then use the arrow keys to highlight the field to be

changed. Use the space key to change the value of a parameter. Use <F12> to return to the top level menu, and <F12> again
to leave setup mode. The user will be prompted at this point if the setup parameters are to be saved for future sessions. Select

Yes by pressing space and then press <F12> again to exit setup mode.

The terminal is delivered pre-configured with the follo wing settings suitable for connection to the SERIMUX SECURE Console
Switch at 9600 baud using VT-100 emulation.
