1.1 Product Overview - Feature Overview
The APC KVM Switch allows you to control up to 64 computers with
one keyboard, monitor and mouse. Each computer can be up to 25 feet
away from the switch. The switch works with IBM PC/AT and PS/2
systems, and 100% compatible machines with support for VGA, SVGA,
XGA and XGA-II video. PS/2 keyboard and PS/2 mouse peripherals
are supported through the rear of the unit.
Expansion for up to 64 computers
An APC KVM Switch unit will support from one to eight attached
computers or channels. If more than eight channels are needed, multiple
units can be cascaded together for expansion. Up to 2 tiers of units can
be connected for a total of 64 attached computers in one system.
On-screen display capability
Configure and control your APC KVM Switch with on-screen menuing.
Name your computer channels anything you wish, then select the
desired computer from an easy-to-use menu. Secondary menus let you
configure and initiate channel scanning and other system features.
Advanced security for total control over system access
Use the advanced two-level security feature to configure and control
server access for every type of user in the system. The administrator
has full access privileges; individual users can have viewing or viewing/
editing capability for each attached server.
IntelliMouse support
The APC KVM Switch offers full support for the Microsoft IntelliMouse.
OSD Configuration Utility
The OSD Configuration Utility allows the administrator to easily
configure and download a channel list with defined users and access
privileges to the entire system. This utility will also read and save your
current configuration for extra security.

Push-button and keyboard switching
In addition to using the on-screen menus, you can switch computer
channels in one of three easy ways: via the APC KVM Switch channel
push-buttons, with the Scan button or with a simple keyboard sequence.
“Keep Alive” feature
APC KVM Switch’s “Keep Alive” feature allows attached servers to
power the unit in the event of a switch power failure. This prevents
attached computers from locking up and keeps you from losing time
and data.
Built-in scanning capabilities
A built-in scanning feature allows you to automatically monitor, or
scan, your computers without intervention. When keyboard activity is
detected, scanning is suspended until all activity stops. Scanning then
resumes with the next channel in sequence.
Status indicator LEDs
Indicator LEDs give you constant readings on the status of your APC
KVM Switch unit. Status, scanning and channel LEDs take the
guesswork out of system operation and diagnostics.

3.1 Basic Operations - Overview
Your APC KVM Switch may be operated in a non-secure (no password
required) or secure (password required) mode. All units ship defaulted
to the non-secure mode. For information on implementing password
security see the “Administrator Functions” section of Chapter 4.
Computers may be powered-up one-at-a-time or all at once. No operator
intervention is required during booting. As the system stabilizes, an
amber LED over each channel will illuminate, indicating that the
attached computer is powered on. A green LED will light at the active
computer. A computer may now be selected via the on-screen display
menu or, if you are in non-secure mode, channel push-buttons, the Scan
button or keyboard hot-key sequence.
The Scan push-button has a green LED over it. Press the button
momentarily to switch to the next computer in sequence. Press and hold
the button for one second to initiate channel scanning. The green LED
will light while you are in scan mode.
There are two status LEDs. The red LED lights if an internal failure
occurs. The green LED will blink for several seconds during power-up
while the system performs a self-diagnostic. After initialization, the
green LED remains lit during normal operation and blinks only when
you are in Command Mode.

3.2 Keyboard Control
The following notational conventions appear throughout this chapter
to illustrate commands for operating the APC KVM Switch. Whenever
you see one of the symbols listed on the left side of the table, substitute
the corresponding steps or values listed on the right side of the table.
Convention

Key Sequence or Value
Enter Command Mode:
1. Press and hold down the ‘Num Lock’ key.
2. Press and release the minus (-) key on the numeric keypad.
3. Release the ‘Num Lock’ key.
Note: For alternate hot-key sequences, see ‘System Control &
Maintenance’ later in this chapter.

Press the ‘Enter’ or ‘Return’ key. The command is used
to execute an instruction and exit from Command Mode.

Addr

The numbers over the push-buttons on your APC KVM Switch
are your servers' addresses. Enter the number, 1-8, for the
computer you're selecting. For cascaded systems, enter the
address of the base unit first.

Example: You have an APC KVM Switch unit cascaded from
channel 2 of your base unit. To access the computer at
channel 3 of this second (cascaded) unit, enter 23.

Press the ‘Escape’ key. The command is used to exit
Command Mode without executing an instruction.

3.3 Keyboard Switching
One of the ways to change the active channel in a non-secured APC
KVM Switch system is by entering a short sequence of keystrokes on
the keyboard. This is called keyboard, or hot-key, switching.
Note: Hot-key switching is only available in the default non-secure state.
For more information on secure versus non-secure operation, see
the ‘Administrator Functions’ section of Chapter 4.
The first set of keystrokes places your system in Command Mode. As
long as you are operating in Command Mode, whatever you type will
be interpreted as channel switch commands until the Enter or the
Escape key is pressed to terminate Command Mode. None of the
keystrokes entered will be forwarded to the attached computer until
you exit Command Mode.
Next, enter the address (Addr) for the channel you wish to select.
Press Enter to accept the new channel. The following command line
shows the proper format used to switch your active channel via keyboard.

5.1 Channel Scanning - Choosing a scan method
APC KVM Switch's scanning feature allows you to automatically
monitor, or scan, your computer channels without intervention. When
keyboard activity is detected, scanning is suspended until all keyboard
activity stops. Scanning then resumes with the next channel in sequence.
Mouse activity will not affect scanning in any way. The length of time
each channel remains on the screen, or dwell time, is configurable and
can be changed at any time.
There are two ways to scan through the channels in your APC KVM
Switch system, either sequentially or numerically.
Scanning sequentially allows you to view each of your active channels
in the order in which they are attached to the APC KVM Switch. The
amount of time each channel remains on the screen, or dwell time, is
configurable and is the same for all channels.
Scanning numerically allows you to scan all your channels in
alphanumeric order according to the channel list in the main OSD
Window. With this scan method, you can adjust the dwell time for each
channel or omit a channel from the scan sequence completely.
Choose whichever method is most appropriate for your configuration.

5.2 Setting the Scanning Order
1. From the main OSD Window, press the Control key twice or type
Alt-M to access the Command Menu.
2. Choose ‘‘Scanning order’’ from the menu.
3. Select either ‘‘Sequential order’’ or ‘‘Alphanumeric order’’.
4. Press Enter.

5.3 Turning Scanning On and Off
From the OSD menu.
1. From the main OSD Window, press the Control key twice or type
Alt-M to access the Command Menu.
2. Select ‘‘Turn scanning ON’’ or ‘‘Turn scanning OFF’’ from the
menu. This is a toggle option - only one scanning option will show
on the menu at any one time.
