Chapter 1
Introduction
Overview
KL1508A / KL1516A KVM switch is a control unit that allows access and
control to multiple computers from a single KVM (keyboard, monitor, and
mouse) console. A single KL1508A / KL1516A can control up to 8 / 16
computers. They consist of an integrated LED-backlit LCD monitor, keyboard,
and touchpad in a 1U rack-mountable retractable sliding housing.
The similarities and differences among the models in the KL1508A / KL1516A
series are shown in the following table:
The LCD and keyboard/touchpad modules slide independently of each other.
To maximize space in your data center, the keyboard/touchpad module slides
back to “hide away” when not in use, while the thin profile LCD monitor
rotates back — flush against the rack — allowing administrators to monitor the
activities of connected computers.
By daisy chaining up to 31 additional switches, as many as 256 / 512 computers
can be controlled from the original KVM console. An auto-sensing function
recognizes the position of each station on the chain, eliminating the need to
manually set the position, and a seven-segment front panel LED displays each
Station's position for easy identification.
Compact, high-density, J-45 connectors and CAT 5e/6 cables make for
simple wiring configuration, with the flexibility to use PS/2 and USB KVM
adapter cables in any combination to link various types of computers,
including PCs, Macs, Sun computers, and serial devices.
Setup of the KL1508A / KL1516A is fast and easy — plugging cables into their
appropriate ports is all that is entailed. There is no software that needs to be
configured nor complex installation procedures.

KL1516AN 19" 16

Access and switching to any computer on the installation is easily
accomplished — either by pressing front panel port selection pushbuttons,
entering hotkey combinations on the keyboard, or by means of a powerful OSD
(On Screen Display) menu system. A convenient Auto Scan function also
permits automated monitoring of all connected computers by switching views
from one to another at set intervals.
Your KL1508A / KL1516A investment is protected through firmware
upgrades. You can download the latest firmware update files from our website,
and upgrade the device with its Firmware Upgrade function.
There is no better way to save time and money than with a KL1508A /
KL1516A installation. By using the KL1508A / KL1516A with its sliding
LCD console to manage your installation, you: (1) eliminate the expense of
purchasing separate keyboards, monitors, and mice; (2) save all the space those
extra components would take up; (3) save on energy costs; and (4) eliminate
the inconvenience and wasted effort involved in constantly having to move
from one computer to another.

KVM console with a built-in 17"/ 19" LED-backlit LCD monitor
in a sliding housing with top and bottom clearance for smooth
operation on a 1U rack.
Dual Rail operation — LCD monitor slides independently of
the keyboard/touchpad.
Console lock enables the sliding console to remain securely
locked away when not in use.
LCD module rotates up to 1 0 degrees for a more
comfortable viewing angle.
LED Light Exclusive LED illumination light — designed by ATEN to
illuminate the keyboard and touchpad to allow visibility in low-
light conditions.
Single Console Control Access and control up to 8 (KL1508A) or 16 (KL1516A)
computers from a single PS/ or USB KVM (keyboard, video,
and mouse) console.
Scalability By daisy chaining up to 31 additional KL1508A / KL1516A
switches, as many as 56 / 51 computers can be controlled
from the original KVM console — eliminating the expense of
purchasing separate peripherals for each server.
Easy Installation Setting up the KL1508A / KL1516A is fast and easy —
plugging cables into their appropriate ports is all that is
entailed. Because there is no software that needs to be
configured, incompatibility and configuration issues are non-
existent.
Easy Operation Three port selection methods: Manual (via front panel
pushbuttons), Hotkey, and multi-language OSD (On Screen
Display).
Keyboard Language support: English (US); English (UK);
German; German (Swiss); French; Spanish; Traditional
Chinese; Japanese; Korean; Swedish; Italian; Russian;
Hungarian and Greek
Hardware Independent
Cross-Platform
Support
The KL1508A / KL1516A supports Windows 000 / XP / Vista
/ 7, Linux, Unix, Novell, FreeBSD, Sun, and Mac.
Space-Saving RJ-45
Connectors and Cat
5e/6 Cabling
This space-saving innovation means that the KL1508A /
KL1516A can be conveniently installed in a 1U system rack,
and the installation can take advantage of the internal
network wiring built into most modern commercial buildings.
Reduces cable clutter for a neat and tidy data center
environment

KVM Adapter Cables
to Connect to Servers
and Devices
For convenience and flexibility, the KL1508A / KL1516A's
design utilizes KVM adapter cables that serve as the medium
between the KVM switch and the connected devices, for
convenient mixing and matching among various interfaces
and platforms.
KVM adapter cables are available in PS/ , USB, and serial
interfaces to support a wide variety of data center servers and
devices.
Two-Level Password
Security
Supports one administrator and ten user profiles. Strong
password protection prevents unauthorized accessing to the
installation — keeping your valuable data secure.
Upgradeable Firmware Stay up-to-date with the latest functionality improvements and
updates by downloading firmware upgrade files from our
website and installing them with the built-in firmware upgrade
utility.
Effortless Upgrades Simultaneous firmware upgrades to all daisy-chained KVM
switches and dongles through the daisy-chain cable.
Auto Scanning and
Broadcast Mode
Auto scanning provides hands-free, automated monitoring of
selected devices by switching among them at variable rates.
Broadcast Mode sends commands from the console to all
computers — allowing you to perform operations (such as
software installation, upgrades, shutdowns, etc.), on them
simultaneously
Superior Video Quality Supports video resolutions of up to 1 80 x 10 4 @ 75 Hz for
up to 50 meters with ATEN KVM Cable Adapter KA7000
series.
Multiple User Accounts Supports up to 10 user and 1 administrator accounts
Hot Pluggable Ability to add or remove components without having to power
off the KVM switch.
Adapter Cables with ID The KL1508A / KL1516A KVM series supports automatic ID
recognition of the ATEN KVM Cable Adapter KA7000 series
(KVM Adapter Cables). Using adapter cables with ID means it
is not required to change cable configuration settings when
moving cables from one port to another.
Device ID and attributes are stored in the adapter cables
allowing you to hot-swap port connections without having to
reconfigure them.
Optional rack mount
kits
Optional rack mount kits available, including easy installation
options.
