2-6 Installation  
WARNING: To reduce the risk of electric shock or damage to  
your equipment, do not disable the power cord grounding  
feature. This equipment is designed to be connected to a  
grounded (earthed) power outlet that is easily accessible to the  
operator. The grounding plug is an important safety feature.  
4. Connect the power cord to the Keyboard/Monitor/Mouse Switch Box.  
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 Chapter 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 that corresponds 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.

2-8 Installation  
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.

3-14 Basic Switch Functions  
You can also connect the mouse and/or keyboard to the switch while the  
system is powered up. When you connect a new device, the switch recognizes  
it, and configures it to the settings of the currently selected computer. This  
technique allows replacement of failed devices without having to restart the  
system.  
NOTE: When new computers are added to the switch, or when  
existing connections are changed, the new configurations should be  
saved in NVRAM. See “Saving the Hardware Configuration.”

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 pairing kit is required for a paired  
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.  
Tiered configuration  
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  
described “Assigning Specific 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 eight-port slave.  
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  
“Assigning Names to Switch Ports.”  
 
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . .  
4-3  
Connecting Tiers while the  
System is Powered 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 number of the port (on the slave unit) to  
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 “Assigning 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.

Regulatory Notices  
Federal Communications Commission Notice  
Part 15 of the Federal Communications Commission (FCC) Rules and Regulations has established  
Radio Frequency (RF) emission limits to provide an interference-free radio frequency spectrum. Many  
electronic devices, including computers, generate RF energy incidental to their intended function and  
are, therefore, covered by these rules. These rules place computers and related peripheral devices into  
two classes, A and B, depending upon their intended installation. Class A devices are those that may  
reasonably be expected to be installed in a business or commercial environment. Class B devices are  
those that may reasonably be expected to be installed in a residential environment (i.e., personal  
computers). The FCC requires devices in both classes to bear a label indicating the interference  
potential of the device as well as additional operating instructions for the user.  
The rating label on the device shows which class (A or B) the equipment falls into. Class B devices  
have an FCC ID on the label. Class A devices do not have an FCC ID on the label. Once the class of  
the device is determined, refer to the following corresponding statement.
