Brief Introduction
The ServerLink 8 port, 16 port or 32 port CAT 5 KVM Switches can control attached servers or computers
from a local or remote console.
They are loaded with features such as one local console port, plus an additional optional CAT 5 based remote
console port or one additional optional IP based remote console port, On-Screen-Display (OSD) menu,
password security, hot-key control, push button port selection and auto scan control. They have complete
keyboard and mouse emulation for simultaneous and flawless server boot-up process.
Designed with intelligent video Gain/EQ (equalizer) adjustments to tweak the video image individually for each
server so that each server can be up to 40 metres away from the console drawer.
With the optional CAT 5 based remote console port you can remotely control servers and computers. You can
locate a second console (monitor, keyboard and mouse) up to 150 metres away from the KVM switch. The
built-in CAT 5 transmitter synthesizes VGA monitor and keyboard/mouse signals and transmits these signals
to the remote CAT 5 receiver over standard CAT 5 or CAT 6 cable.
With the optional IP based remote console port you can control connected servers locally at the rack or
remotely via the Internet using a standard browser. You can securely gain BIOS level access to systems for
maintenance, support or failure recovery over the Internet. Communication is secure via SSL encryption.

Chapter 2 Hardware Installation
Before installation, please make sure all of peripherals and computers have been turned off.
Please Note: The recommended power ON sequence is as follows: monitor, then KVM switch and finally
computers.
2.1 Connect CAT 5 KVM Dongles to Computers
Plug your USB/VGA and/or PS2/VGA CAT 5 KVM Dongles into the computers you want to connect to the
KVM switch.
2.2 CAT 5 KVM Installation – Access up to 8 / 16 /32 Computers
1. Connect a CAT 5 cable between the RJ45 CAT5 KVM port and the KVM Dongle.
2. Install Remote Console Extension Unit (Optional): Connect a CAT 5 cable between Optional Remote
Console Extension Unit and the CAT 5 KVM [LINK] port. For image EQ, Gain and RGB Skew adjustment,
please refer to the user manual included with the Extension Unit.
2.3 DDC-2 Protocol Support
The CAT 5 KVM Switch supports the DDC-2/EDID protocol. This enables all connected computers with DDC-
2 compatible graphics cards to automatically set compatible resolutions and refresh rates. The CAT 5 KVM
switch handles DDC-2 as follows:
1. As the CAT 5 KVM powers on, it checks for a local monitor and sends the DDC-2/EDID information of this
local monitor to all connected KVM Dongles.
2. To make sure each connected KVM Dongle has the latest EDID information, the CAT 5 KVM will resend
the DDC2B/EDID information to the KVM Dongle each time it switches to a new port.
2.4 Hot Plugging
The CAT 5 KVM supports hot plugging. The CAT 5 KVM Dongle can be removed and added by unplugging or
re-plugging without the need to power off the LCD console drawer.

Chapter 3 Operation
3.1 Port Selection by OSD Menu
The CAT 5 KVM provides a user-friendly OSD (On-Screen-Display) interface. The OSD menu can be
activated by using Hotkeys.
To activate the OSD, press the <Scroll Lock> key twice within two seconds. You will see the OSD Main Menu
screen showing a list of the computers with corresponding KVM port channel ID numbers, names and status.
See the following picture.
The default OSD Hotkey is <Scroll Lock> twice. Alternatively you can change to <Shift>, <Alt> or <Ctrl>
(See Chapter 3.3 Define Hotkey)
The CH and Name displayed in yellow indicates the computer is powered ON and can
be accessed.
The CH and Name displayed in white indicates the computer is powered OFF.
3.2 Selecting a Computer
1. The currently selected Channel ID is displayed in the upper right hand corner.
2. Navigate to the desired computer with the arrow keys and press <Enter>. The selected computer’s screen
appears on the monitor, with a confirmation label (shown below) which identifies the connected computer.
Use the console keyboard and mouse to control the selected computer.
3.3 OSD Hotkey Functions
F1: Auto (Auto Scan)
In this mode, the console automatically switches from one powered-on computer to the next sequentially in
fixed interval timing. During the scanning, the OSD will display the name of the computer being scanned.

During this mode, you can press <Space> or <Enter> key anytime to access the scanned computer. Press
<Esc> to abort the [Auto Scan] mode. You can also press <↑> or<↓> key to enter a [Manual Scan] mode.
You will see the following screen.
In [Manual Scan] mode, you can scan powered-on computers one by one by keyboard control. Press <↑> to
previous computer and <↓> to select the next computer. Press <←>, <→> to move the OSD position.
To abort [Manual Scan] mode, press <ESC>.
F2: Name (Port Name)
To help remember which computer or Slave CAT 5 KVM is attached to a particular port, every KVM port of the
CAT 5 KVM can be given a name. To edit the name of a computer, press <F2>, and enter up to 8 characters.
Valid characters are ‘A’~’Z’, ‘0’~’9’ and ‘-‘. Lowercase are converted to uppercase. Once the port name is
given, it will be saved in the KVM Dongle. If you move the KVM Dongle to a different port, the port name will
stay with the KVM dongle. The name will stay with the KM dongle until you manually modify or delete it.
F3: Secu (Security)
This function protects individual computers from unauthorized access. By default the Security function is
disabled. To enable, high-light the computer you want to protect then press <F3>. A “1” mark will show
indicating the Security function is enabled for that port.
10
To access a locked computer, highlight it and press <ENTER>; the admin password challenge appears. After
entering the correct password, you are allowed to control the selected computer. The computer is
automatically re-locked once you switch to another computer.
To disable the password-protected function, select the computer and press <F3> again and enter the correct
password.
Note: The Password-protected computers (“1” marked) are skipped during [Auto Scans and [Manual
Scan] modes.
F5: Manu (Manual Scan)
Press <F5> to enter [Manual Scan] mode. An OSD similar to the following appears:
In this mode, you can scan powered-on computers one by one by keyboard control. Press the <↑> key to
select the previous computer and the <↓> key to select the next computer. Press the <←>, <→> to change
the OSD position.
To abort [Manual Scan] mode, press <ESC>.
F6: (Check Mark)
This is a scan filter. In order to limit [Auto Scan] or [Manual Scan] to certain computers, mark the computers
with a check mark “V”. To set, highlight the computer, and press <F6> to toggle the mark on or off. Use “Scan
Type” to set up scanning so it includes just the computers you checked.
11
There are two Scan Type options for Scan mode:
[Ready PC]: will scan all powered-on computers, except those with the Security “1” setting.
[Ready PC + V ]: will scan only powered-on computers that have a check mark “V”, except those with the
Security “1” setting.
To cancel the check mark “V”, press <F6> again.
F7: ACPI (Green command)
Before you start using ACPI commands in the KVM, you should confirm the settings in the BIOS work with
ACPI commands. The following are introductions of setting BIOS to support ACPI commands; we’ll follow
Phoenix BIOS’s settings for example, which is one of the global leading BIOD brands.
* Note:
ACPI (Advanced Configuration and Power Interface)
ACPI (Advanced Configuration and Power Interface), a power management specification developed by Intel,
Toshiba and Microsoft that makes hardware status information available to the operating system.
ACPI combines the earlier Advanced Power Management (APM) and PnP BIOS into an enhanced power
management system. ACPI support is built into Windows starting with Windows 98; however, the PC's chipset
and BIOS must also support it. It provides a platform-independent, industry-standard approach to operating-
system-based power management. The ACPI specification is the key constituent in OSPM (Operating System
Directed Power Management). OSPM and ACPI apply to all classes of computers, including handheld,
notebook, desktop, and server machines.
The ACPI OS takes over the power-management and Plug and Play functions from the legacy BIOS
interfaces and allows inexpensive power-management hardware to support elaborate power-state transitions,
maximizing the computer's power consumption and resource-utilization efficiencies.
