Hardware Installation

Before installation, please make sure all of peripherals and computers have been turned off.

2.1 Computer/Server Installation

Fig1 Figure 3. Computer/Server Installation

2.1.1 Connecting KVM switch to the host system
In order to connect the KVM switch of the host system performs the following steps:
Step 1. Power up your KVM Switch by connecting the power cord to it.
Step 2. Connect the shared USB keyboard, and mouse to the KVM switch.
Step 3. Connect each of your computers to the KVM switch, using the DVI video cable.
Step 4. Power up the connected computers one by one. After your computers are powered up, the keyboard and mouse will be recognized and now you can begin operating the KVM switch.

2.2 Power-Up Sequence
Double-check whether all cables/connectors are properly connected. You can check the keyboard and mouse connectors to ensure the connectors and cables are connected correctly.
The recommended Power Up sequence is as follows: Monitor, KVM Switch, and finally the computers.
Verify that all servers connected to the KVM Switch are powered on. If any connected servers have not been powered on, it is okay to do so at this time (servers can be powered on simultaneously).
The KVM Switch emulates both a mouse and keyboard on each port and allows your server to boot normally.

Rack Installation

Step 1

Step 3
Position the LCD console drawer so the two rear slide rails will slide into the main body of the LCD console drawer. Attach the mounting ears of the LCD console drawer to the front vertical mounting rails of the rack cabinet using standard M cage nuts and screws.

Usage

Now that you have connected your console and servers to your KVM Switch, it is ready for use.
You can control the KVM switch by two methods:

Using push buttons located on the LED panel of the KVM Switch
Using hot-key commands through the console keyboard
It takes a few seconds for the video signal to refresh after switching servers. Re-synchronization of the mouse and keyboard signals also occurs. This is a normal operation and ensures that proper synchronization is established between the console and the connected servers.

4.1 Hotkey Commands

The default Hotkey is Scroll Lock + Scroll Lock, then the keys on the following table list.

Command	Function

↑ or↓

| To switch to the previous/next port

Port No.

| To switch to a specific port
-e.g. Port 4: Scroll Lock + Scroll Lock + 0 + 4
-e.g. Port 12: Scroll Lock + Scroll Lock + 1 + 2

B

| To enable/disable the beep sound function.

S

| To activate the Auto-scan function.

You must press the hotkey within 2 seconds
A beep sound will be heard for successful entering

4.2 Hot Plug
The KVM Switch supports the “Hot Plug” function for USB keyboard and mouse connectors.

Note:

Normally, the USB port is Hot-pluggable, but some OS (Operation Systems), like Sun Micro and some Unix and Linux, do not support the USB Hot Plug function. If you apply Hot Plug to this kind of OS, it will cause unpredictable behavior or shut down the computer. Before attempting to use Hot Plug, please make sure the OS and mouse software driver support the Hot Plug function.

Troubleshooting

1. No LED display on KVM Switch

Make sure the power adapter is plugged into the KVM Switch. If the LEDs still won’t light, perform a soft reset to the KVM switch.
Power cycle KVM switch.

2. The computer has started up, but the keyboard or mouse won’t work

Make sure your keyboard and mouse work fine if directly plugged into the computer.
Please unplug and plug in the USB connector, wait a few seconds for USB bus emulations and start up the process to complete.
Do not press any keys on the keyboard while the selected computer is booting up.
Otherwise, it might cause the keyboard error or the keyboard is not detected at the Host side.
Try a different keyboard, but use only a 101/102/104-key keyboard.
Power cycle KVM switch.
Avoid moving the mouse or pressing the mouse buttons when switching ports.

3. No video signal is displayed on the LCD monitor.

Connect another monitor directly to the server to verify that your monitor is functioning properly.
Please check if all connectors are connected properly
The power adapter is not connected to the KVM switch.
See next item, make sure the computer VGA output resolution matches the monitor’s resolution

4. The computer resolution does not match the monitor’s resolution

Make sure the resolution works fine if directly connecting the monitor to the computer.
Please turn off the computer, wait a few seconds then turn it on again. Notice that during computer startup, it will try to obtain the information of the connected monitor resolution from its related port. So before computer startup, the monitor and KVM switch should be already ON and running.
The DDC function of KVM Switch will dynamically detect and copy the DDC data from the monitor that is attached to the LOCAL console port, and that data will feed to the host computer during computer startup.
The recommended Power ON sequence is as follows: monitor, KVM Switch, and finally the computers.

Glossary

The following definitions are used throughout this User Manual.

Auto-Scan: A mode of operation where the KVM switch scans from one port to another, on an ongoing basis, as configured by the user.
Console: The all-in-one term for the keyboard, video monitor, mouse, and audio connected to a KVM switch.
Console Port: An interface receptor on the KVM switch for the console to connect to the KVM switch via cables.
Control: When discussing switching between ports, control means that the console is capable of sending input to the server. Control requires that the console also has focused on the port, and is viewing it.
DDC: Short for Display Data Channel, a VESA standard for communication between a monitor and a video adapter. Using DDC, a monitor can inform a computer’s video card about its properties, such as maximum resolution and color depth, to ensure that the user is presented with valid options for configuring the display.
HID: Human Interface Device, the USB device class that includes keyboards and mice.
Host/Computer Port: An interface receptor on the KVM switch for the computer/server to connect to the KVM switch via cable.
KVM: Literally “Keyboard Video Mouse”, this term refers to technology that allows two or more computers to be controlled by one keyboard, video monitor, and mouse; some switches that use KVM technology enable sharing of other peripherals such as audio speakers, microphones, and printers.
KVM Switch: A device that allows a user to access and control multiple servers from a single console. It has at least one console port and multiple server ports.
