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
g
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.
