To reduce the ris k of electric s hoc k or dam age to
Initial Power-up
It is important that you power up the Keyboard/Monitor/Mouse Switch Box
first, then the computers. This is because when the servers boot up, their
drivers send device settings to the switch. These settings are then stored in the
switch NVRAM. Power-up the system as follows:
1. Power up the switch by pressing the power switch located on the rear
panel to the on (1) position.
2. Power up the computers.
Keyboard/Monitor/Mouse
Switch Box Startup Behavior
Power up the Keyboard/Monitor/Mouse Switch Box first. During startup, the
unit does the following:
■
Identifies the mouse and keyboard and puts them into default states.
■
Switches to port number 1 by default, and displays the number “1” in
the status flag displayed on the monitor. If the status flag default
setting has been changed to Names mode, the status flag displays the
port name instead of the port number. If a status flag is not being
shown on the monitor, make sure that it is connected and powered up.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
2-7
Computer Startup Behavior
During startup the computers send device settings to the
Keyboard/Monitor/Mouse Switch Box. The unit then generates standard
responses to these commands and allows the computers to boot successfully
without actually being physically connected to the devices. Once you have
the switch installed you can save these settings to non-volatile RAM
(NVRAM). See Chapter 3 for additional information.
Configuring the
Keyboard/Monitor/Mouse
Switch Box
When you first power up the Keyboard/Monitor/Mouse Switch Box, no
configuration is needed for normal switching operation. For tailoring the unit
to meet your specific needs, such as assigning unique names for the
computers, or displaying the computers by their assigned name or port
number, see Chapte r 3.
Switching Between
Computers
Switching from one computer to another is a simple process with the
Keyboard/Monitor/Mouse Switch Box. Switching disconnects the keyboard,
mouse, and monitor from one computer and connects them to another. The
steps are as follows:
1. Press Print Scrn.
2. Select the computer you want to switch to by using the Up and Down
arrow keys, or by pressing the numeric key t ha t c orre sponds to the
computer’s port number.
3. Press Enter.
Since the Print Scrn key is used to start the switching process, you cannot use
it to print a screen in the normal way. To print the screen, simply press Print
Scrn twice. For more information on switching, see Chapter 3.
Compaq Keyboard/Monitor/Mouse Switch Box User Guide
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
2-8 Installat ion
Whenever you switch between two computers, the Keyboard/Monitor/Mouse
Switch Box reconfigures the keyboard and mouse using the settings stored in
its memory. For example, if the current computer selected has Caps Lock
turned On, but the user is switching to a second computer that has Caps Lock
turned Off, then the unit turns Caps Lock Off to match the setting for the
second computer.
Unattended Reboot
After a power outage, each server connected to the Keyboard/Monitor/Mouse
Switch Box reboots (if designed to do so), without operator intervention, when
power returns. The switch generates responses to ensure that the reboot is
successful and that the Keyboard/Monitor/Mouse Switch Box is ready to
switch between computers.

Alternate Configurations
There are other ways to configure your system, including paired switch
configurations and tiered switch configurations. This chapter provides brief
descriptions, installation instructions, and hardware requirements for these
alternate configurations.
Paired Switch Configurations
Two eight-port Keyboard/Monitor/Mouse Switch Box units can be connected
or paired together to effectively double the capacity of the system. To operate
two switch box units in a paired configuration, mount one on top of the other
and interconnect them by means of the pairing kit cables. The Interconnect
Cable Kit (pairing kit) consists of one RJ45 interconnecting cable and three
‘Y’ cables as shown below. The pairi ng kit i s require d for a pai re d
configuration and is available through your Compaq Authorized Reseller.

4-2 Alternate Configurations
Tiered Switch Configurations
In tiered systems, you can connect additional switches to ports on a master
unit. That is, switches can be tiered in master/slave configurations to allow
one master switch to switch between computers or other switch units. Tiering
simply involves linking the slave units’ physical keyboard, mouse, and
monitor connections to one of the computer ports on the master unit. For
example, one eight-port master unit can accommodate eight slave switch
units. This system with eight servers connected to each of the eight slave
switches would provide a 1x64 concentration. An example of a tiered switch
configuration is shown below.
System 1 - 8
System 9 - 16
HYDR-006.EPS
Figure 4-2.
When connecting a slave unit to one of the ports of the master unit, you need
to indicate this connection to the master unit by performing the previously
descri b e d “ Assi g n i n g Sp ecific Device Types” procedure, but entering slave
unit designation for the associated port number instead of a monitor type. Use
the designation 4port for a four-port slave and 8port for an e i ght-port sla ve.
CCR allows slave ports to be treated much like ports on the master switch. It
may be helpful to name each slave unit as previously described under
“Assigni n g Names to Switch Ports.”
Tiered configuration

4-3
Connecting Tiers while the
System is Po wered Up
If necessary, you can connect a master unit to a slave unit while the system is
powered on. This technique can be used to isolate any problems with a
minimum disruption to the system. When plugging a master
Keyboard/Monitor/Mouse Switch Box into a slave unit, you must first connect
the mouse and video cables, then connect the keyboard cable. This is because
the master unit interprets the keyboard connection as the slave unit’s power
up. At this point the master unit sends initialization codes to the slave unit,
triggering device configuration.
Switching Tiered Systems
To switch the Keyboard/Monitor/Mouse Switch Box to a computer that is
connected to the master through a slave unit, proceed as follows:
1. Press Print Scrn. The CCR Selection window appears on the monitor.
2. Type the number of the port to which the slave unit is connected
followed by a dash and the numbe r of t he port (on t he sla ve unit ) t o
which the computer is connected. For example, to switch to the
computer connected to port 3 of a slave unit connected to port 1 of the
master, press Print Scrn, 1, -, 3.
If the computer/slaves are listed in the window by name (as described
in “Assig n i n g Names to Switch Ports”), then type the assigned name of
the computer. If no slave unit is connected to the selected master port,
the command is canceled when you enter the slave number.
3. Press Enter.
