2. Overview
2.1 Introduction
The 4-, 8-, or 16-Port ServSwitch™ allows you to control up to 4, 8, or 16 PS/2®and
USB server computers from a single PS/2 console (PS/2 keyboard, PS/2 mouse,
and monitor). Supported mice include Microsoft®IntelliMouse®and other mice.
The ServSwitch offers an efficient way to manage multiple computers in server
rooms where space is at a premium. On Screen Display (OSD) features computer
naming, computer selection, status indication, AutoScan, and more. Up to 136
servers can be easily managed by cascading multiple KVM switches. The switch has
one HD15 connector for each computer connection.
Use front-panel buttons, the on-screen display (OSD) interface, or hotkeys to
switch the KVM control. The front panel also includes port LEDs. The LED will
light with the corresponding active port when manually switching between the
computers. Navigate through the OSD menus using function keys (see Section 4.3
for details). Using a hotkey command sequence (see Section 4.4), you can switch
the KVM control. The ServSwitch beeps to confirm that it’s in hotkey mode.
The AutoScan function allows you to automatically scan and monitor all
computers, one by one, that are connected to the ServSwitch. And the ServSwitch
works with most common Windows®operating systems.
The ServSwitch supports video resolutions of up to 1920 x 1440.

NOTE
If you forget the password, the only way to permanently erase all the
passwords for the KV9108A or KV9116A is to press and hold the front
panel buttons 1 and 2, then press and hold 7 and 8. Release 7 and 8,
then release 1 and 2. For the KV9104A, press 3 and 4 instead of 7 and 8.
Function key F4 enables more functions, including AutoScan, Manual Scan, Scan
Type, Scan Rate, Keyboard Speed, Hotkey Menu, CH Display, and Position. A new
screen pops up displaying these functions as described on the next two pages. Most
of them are marked with a triangle, indicating there are options to choose from.
Use the up-arrow or down-arrow key to select the functions, and then press the
Enter key. Available options will be shown in the middle of the screen. Again, use
the up-arrow or down-arrow keys to view each option, and then press the Enter key
to select it.
Press the Esc key to exit the OSD at any time and return to the port/PC screen that
you were previously connected to.
