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.


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


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.




. . . . . . . . . . . . . . . . . . . . . . . . . . . . . .


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.

Resetting the Unit

If the keyboard or mouse locks up, you can push the Reset button on the back panel to reset the switch. Pressing the Reset button may allow you to recover the device settings without power cycling the computers.

Making Connections Under

Power

You can connect additional computers to the switch while it is running. When you power up the newly connected computers, the switch recognizes them, and you can switch to the new computers without taking any additional steps.




. . . . . . . . . . . . . . . . . . . . . . . . . . . . . .


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.”

Chapter 4

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.


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.
