Local

Over the

NET

Introduction

Overview

The KH1508Ai / KH1516Ai KVM Over the NET™ switches are control units that allow access to multiple computers from a single KVM (keyboard, monitor, and mouse) console.

A single KH1508

Ai / KH1516Ai can control up to 8 / 16 computers. As many

as 15 additional KVM switches can be daisy chained from the original unit, so that up to 256 computers can all be controlled from the original KVM console.

Note: See Supported Devices, page 182, for a list of KVM switches that can

be installed on a KH1508Ai / KH1516Ai daisy chain.

Since the KH1508

Ai / KH1516Ai uses TCP/IP for its communications

protocol, it can be accessed from any computer on the Net – whether that computer is located down the hall, down the street, or half-way around the world.

In addition to TCP/IP connectivity, the KH1508

Ai / KH1516Ai provides local

ports for a locally attached USB or PS/2 console and a Laptop console – allowing access and control from the data center as well as over the Net. The switches utilize a single shared bus implementation – although they support local and remote login at the same time, they do not support independent operation. If a local user logs in while a remote user has already opened a session, the local user sees the same screen that the remote user is working on.

KH1508Ai / KH1516Ai User Manual

For local access, the KH1508Ai / KH1516Ai supports resolutions of 1600x1200@60Hz for an extended distance of up to 40 m, as well as 1280x1024@75Hz for an extended distance of 50 m. For remote access, the switches support up to 1280x1024@75Hz.

The switches feature RJ-45 connectors and Cat 5e/6 cable to link to the computers. Utilizing PS/2, USB, and serial KVM Adapter Cables for the final linkup, the KH1508

Ai / KH1516Ai permits any combination of PCs, Macs, Sun

computers, and serial devices to coexist on the installation. Use of the adapter cables dramatically reduces cable clutter, and makes reconfiguring the installation easy and convenient.

A custom ASIC (patent pending) provides an auto-sensing function that recognizes the position of each station on the chain, eliminating the need to manually set the position with DIP switches. A seven segment front panel LED displays each Station's position for easy identification.

The KH1508

Ai / KH1516Ai has been designed to work seamlessly with the

ALTUSEN CC2000 Control Center Over the NET™ for ease of access and administration. It also allows the IP address configuration to be easily configured from the local console OSD.

Your KH1508

Ai / KH1516Ai investment is protected by a firmware upgrade

utility. You can stay current with the latest improvements in functionality by downloading firmware update files from our website, and using the utility to quickly and conveniently install them.

Setting up the KH1508 their appropriate ports is all that is entailed. Because the KH1508 KH1516

Ai intercepts keyboard and mouse input directly, there is no software

to configure; no need to get involved in complex installation routines; no need to be concerned with incompatibility problems.

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

There is no better way to save time and money than with a KH1508 KH1516 computers, a KH1508

Ai installation. By allowing a single console to manage up to 256

Ai / KH1516Ai installation: (1) eliminates the expense of

having to purchase a separate keyboard, monitor, and mouse for each; (2) saves all the space those extra components would take up; (3) saves on energy costs; and (4) eliminates the inconvenience and wasted effort involved in constantly moving from one computer to another.

Hardware Setup

Overview

For convenience and flexibility that allows mixing the PS/2, USB, and serial device interfaces, as well as multiple platforms, the KH1508 design utilizes KVM Adapter Cables (CPU Modules), that serve as intermediaries between the switch and the connected devices (refer to the installation diagram on page 15).

A separate KVM Adapter Cable is required for each computer or device connection. See KVM Adapter Cables, page 6 for the model numbers.

To place the KH1508 remove 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:

Ai / KH1516Ai, or to stack units if you are daisy chaining them,

Note: To ensure adequate ventilation, allow at least 5.1 cm on each side, and

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

Single Station Installation

In a single stage installation, there are no additional KVM switches daisy chained down from the KH1508 installation, refer to the installation diagrams starting on page 15. The numbers in the diagrams correspond with the numbers of the instruction steps, below:

Ai / KH1516Ai. To set up a single stage

1. Ground the KH1508

Ai / KH1516Ai by connecting one end of a grounding

wire 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 keyboard, monitor, and mouse into the unit’s console ports. Ports are color coded and marked with icons for easy identification.

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

3. If you are using a laptop USB console to control the KH1508Ai / KH1516 connect the laptop to the KH1508

Ai locally, use the laptop USB cable included in the package to

Ai / KH1516Ai’s Laptop port, located on

the unit’s front panel.

4. 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 6 for details).

Note: To support a resolution of 1280x1024@75Hz, the recommended maximum

distance between the unit and the KVM adapter cable is 50 meters; to support a resolution of 1600x1200@60Hz, the recommended maximum distance is 40 meters.

5. 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.)

6. Plug the LAN or WAN cable into the KH1508

7. Plug the female end of the power cord into the KH1508

Ai / KH1516Ai’s LAN port.

Ai / KH1516Ai's

power socket; plug the male end into an AC power source.

After the KH1508

Ai / KH1516Ai is cabled up, you can turn on the power. After

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

Daisy Chaining

To control even more computers, up to 15 additional KVM switches can be daisy chained from the original KH1508 computers can be controlled from a single console in a complete installation.

Note: Please see the table, Supported Devices, page 182, for a list of ATEN

switches that can be installed on a KH1508Ai / KH1516Ai daisy chain.

Tables showing the relation between the number of computers and the number of KH1508

Ai / KH1516Ai units needed to control them are provided on

page 181.

To set up a daisy chained installation, do the following:

1. Use a daisy chain cable set to connect the Chain Out port of the parent KH1508

Ai / KH1516Ai unit to the Chain In port of the child unit (first

station out to second station in, second station out to third station in, etc.).

Note: 1. You cannot use the chain in port of the First Station, since it is the

highest level parent.

2. Daisy chain cable sets require a separate purchase. Contact your dealer for details.

Ai or KH1516Ai. As many as 256

2. Cable up the computers and the switch according to the information provided under Single Station Installation, page 14.

3. Repeat the above for any other switches you want to add to the chain.

4. Power up the installation according to the following procedure:

a) Plug in the power cord for the first station. Wait for the unit to ascertain

its station ID and display it on the Station ID LED. (The station ID for the first stage unit is 01, the ID for the second stage unit is 02, the ID for the third stage unit is 03, etc.)

b) Power on each station on the installation in turn (second station, then

third station, etc.). In each case, wait for the station ID to be ascertained and displayed before powering on the next station.

c) After all the stations are up, power on the computers.
