Chapter 1

Introduction

The Compaq Keyboard/Monitor/Mouse Switch Box is a device that switches a

single keyboard, mouse, and monitor between multiple Compaq computers.

The Keyboard/Monitor/Mouse Switch Box is a space-efficient 1 U height

(1.75-inch) device and is available in four- and eight-port models. This

chapter provides an overview of the product features, functionality, and

sample configurations.

Compaq

Keyboard/Monitor/Mouse

Switch Box Features

The Keyboard/Monitor/Mouse Switch Box products provide Compaq users

with a complete Compaq solution for their server computing needs. You can

use the Keyboard/Monitor/Mouse Switch Box in various configurations to

connect from 2 to 64 servers.

The features of the Keyboard/Monitor/Mouse Switch Box include:

■Console Configuration Reporting (CCR) - Console Configuration

Reporting displays system-related information on the monitor, such as

power-up test data and configuration menus.

■Programmable Scanning - You can evaluate system performance by

sequentially scanning any or all of the computers in the system.

Programmable scanning allows you to determine which computers to

include as well as the duration of the connection.

■Configuration NVRAM - NVRAM (non-volatile RAM) makes it easy

to set configuration information using commands entered from the

keyboard. The NVRAM stores the resulting configuration until you

decide to change the information, even if the unit loses power.

■Hardware Reset Switch - If the keyboard or mouse communication is

disrupted, you can press this switch to reset the unit.

■External Keypad Jack - The Keyboard/Monitor/Mouse Switch Box

has an external keypad jack to support rack-mounted Compaq products.

In this configuration, the switch is mounted behind a door in a cabinet

and the optional keypad is mounted outside the cabinet for easy access.

■Password Protection - For protection against unauthorized users, the

Compaq Keyboard/Monitor/Mouse Switch Box provides a password

option for security purposes.

Configurations

There are many ways to configure your Compaq Keyboard/Monitor/Mouse

Switch Box in order to meet your specific organizational needs. Additional

information on configuring multiple Keyboard/Monitor/Mouse Switch Boxes

can be found in Chapter 4.

■A single Keyboard/Monitor/Mouse Switch Box is used to connect four

or eight servers. In this configuration, the keyboard, monitor, and

mouse are connected directly to the unit by their respective cables.

You can connect the Keyboard/Monitor/Mouse Switch Box to servers

located in the same or adjoining racks. See Figure 1-1.

■You can pair two Keyboard/Monitor/Mouse Switch Box units to

connect up to 16 computers. In this configuration, two eight-port

switches are placed one on top of another with a cable connecting

them. This requires only 2U (3.5 inches) of vertical space. For

additional information, see Chapter 4, “Paired Switch Configurations.”

■You can tier multiple Keyboard/Monitor/Mouse Switch Box units to

connect up to 64 servers. This configuration is often referred to as a

“master/slave” system. It is illustrated in the example below, with the

slave unit’s device port connected to one of the computer ports on the

original or master unit. Multiple Keyboard/Monitor/Mouse Switch

Box units can be tiered from the master unit. See Figure 1-2.

Installation

This chapter provides installation information for the Compaq

Keyboard/Monitor/Mouse Switch Box.

WARNING: To reduce the risk of personal injury or damage

to the equipment be sure that; the leveling feet are extended to

the floor and supporting the full weight of the rack. Each rack

should be level and stable. Racks that are not coupled to

ether

require the installation of stabilizing feet. This must be

accomplished before performing any work on the rack.

WARNING: Risk of personal injury. The rack may become

unstable if more than one component is extended for any

reason. Always ensure that the rack is adequately stabilized

before extending a component outside the rack. Extend only

one component at a time.

Attaching the Slide Rail

Brackets

The figure below shows how to attach the slide rail brackets to the

Keyboard/Monitor/Mouse Switch Box. Make sure that the front end of the

rack-mount brackets angle out away from the unit.
