Introduction

Overview

A KH2508A/KH2516A KVM switch is a control unit that allows IT administrators to access and control multiple computers from two PS/2 or USB KVM (keyboard, monitor, and mouse) consoles. Operators working at up to two consoles can independently and simultaneously take control of up to 8 (KH2508

By daisy chaining up to 31 additional switches, as many as 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, RJ-45 connectors and CAT 5e/6 cable make for a compact, efficient, wiring configuration, while the use of PS/2 and USB KVM Adapter Cables to link to the computers, permits any combination of PCs, Macs, Sun computers, and serial devices to coexist on the installation.

A), or 16 (KH2516A) computers.

Setting up the KH2508 their appropriate ports is all that is entailed. Because the KH2508 intercepts keyboard and mouse input directly, there is no software to configure and no complex installation routines.

Access to any computer on the installation is easily accomplished – either by pressing front panel port selection pushbuttons; entering hotkey combinations from the keyboard; or by means of a powerful OSD (On Screen Display) menu system. A convenient Auto Scan function also permits automatic scanning and one-by-one monitoring of the activities of selected computers.

Features Benefits

Auto Scanning and Broadcast Mode

Auto scanning provides hands-free monitoring of selected devices 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 the video resolutions up to 1600x1200@60hz for up

to 40 meters, and 1280x1024@75hz for up to 50 meters with the new ATEN KVM Cable Adapter KA7000 series.

Multiple User Accounts Supports up to 10 user and 1 administrator accounts

Port Operation Modes Diversified port operation modes (Occupy, Exclusive, and

Share) enable flexible computer and access rights management between the two consoles.

Hot Pluggable Ability to add or remove components without having to power

off the KVM switch.

Adapter Cables with ID The KH2508

A / KH2516A KVM series supports automatic ID

recognition of the new ATEN KVM Cable Adapter KA7000 series (See KVM Adapter Cables on page 5). Using the new adapter cables with ID means it is not required to change cable configuration settings when moving cables from port to port.

Device ID and attributes are stored in the adapter cables allowing you to hot-swap port connections without having to reconfigure attributes.

Hardware Setup

Overview

For convenience and flexibility that allows mixing the PS/2, USB and serial interfaces, the KH2508 serve as intermediaries between the KVM switch and the connected devices:

A separate KVM adapter cable is required for each computer or device connection. The KVM adapter cables are listed in the KVM Adapter Cables section on page 5. Consult your dealer to find out which KVM adapter cables best fit your needs.

Before you Begin

Stacking and Rack Mounting

The KH2508A / KH2516A can be stacked on the desktop or rack mounted at the front or rear of the rack. The following sections take you through the procedures for each method.

Note: 1. Allow at least 5.1 cm on each side for adequate ventilation and

12.7 cm at the rear for power cord and cable clearance.

2. The standard rack mount kit does not include rack mount screws or cage nuts. If you need additional rack mount screws or cage nuts, contact your rack dealer.

Stacking

The KH2508A / KH2516A can be placed on any appropriate level surface that can safely support its weight plus the weight of its attached cables. To place the KH2508 the backing material from the bottom of the rubber feet that came with this package, and stick them onto the switch’s bottom panel at the corners, as shown in the diagram, below:

Rack Mounting

The KH2508A / KH2516A can be mounted in a 19" (1U) rack. The mounting brackets can screw into either the front or the back of the unit so that it can attach to the front or the back of the rack. To rack mount the unit:

1. Remove the screws at the front or the rear, as shown in the diagram below.

2. Screw the mounting brackets into the sides of the unit at the front or the rear, as shown in the diagram below.

3. Slide the unit into the front or rear of the rack and secure it to the rack.

KH2508A / KH2516A User Manual

Single Station Installation

In a single stage installation, there are no additional KVM switches daisy chained down from the KH2508 installation, refer to the installation diagrams starting on page 15 (the numbers in the diagram correspond with the numbers of the instruction steps), and do the following:

A / KH2516A. To set up a single stage

1. Ground the KH2508

A / KH2516A by connecting one end of the grounding

wire provided with your switch to the grounding terminal, and the other end of the wire to a suitable grounded object.

Note: Do not omit this step. Proper grounding helps to prevent damage to

the unit from surges or static electricity.

2. Plug the the console keyboards, monitors, and mice into the unit’s Console 1 and Console 2 console ports. The ports are color coded and marked with icons for easy identification.

Note: You can use any combination of keyboard and mouse connections.

For example, you can use a PS/2 keyboard with a USB mouse.

3. Use Cat 5e/6 cable to connect any available KVM port to a KVM adapter cable that is appropriate for the computer you are installing (see KVM Adapter Cables, page 5 for details).

Note: To support a resolution of 1280x1024, the recommended maximum

distance between the KH2508

A / KH2516A and the KVM adapter

cable is 50 meters.

4. Connect the KVM adapter cable to the computer.

Plug the connectors on the KVM adapter cable into the appropriate ports of the computer you are installing. (See KVM Adapter Cable Installation Diagrams, page 16 for connection examples.)

5. Plug the female end of the power cord into the KH2508 power socket; plug the male end into an AC power source.

After the KH2508

A / KH2516A is cabled up, you can turn on the power. After

it is powered up, you can turn on the servers.
