Introduction

Overview

The KH98 KVM Switch offers multiple computer access and IPMI based monitoring from a single console (keyboard, monitor, and mouse).

IPMI (Intelligent Platform Management Interface) is quickly becoming the industry standard for remote network infrastructure troubleshooting and failure prevention.

IPMI provides server hardware health monitoring including CPU temperature, voltage, fan speed, etc., along with other remote maintenance features like system reset and power on/off. Best of all, IPMI can still be deployed remotely even if the system is down (Out of Band). For more information on enabling IPMI functionality, see F5 BMC:, page 31.

The KH98 allows users to manage and maintain company infrastructure in a cost effective manner. A single KH98 can manage up to 8 computers. Since units can be cascaded to three levels, in a full three stage installation up to 73 KH98 units can control and monitor up to 512 computers - all from a single console. See Installation, page 9 for additional information.

Setup is fast and easy; plugging cables into their appropriate ports is all that is entailed. There is no software to configure, so there is no need to get involved in complex installation routines or be concerned with incompatibility problems. Since the KH98 intercepts keyboard input directly, it works on any hardware platform and with all operating systems.

There are three convenient methods to access any computer connected to the installation: (1) using the pushbuttons located on each unit's front panel; (2) entering Hotkey combinations from the keyboard; and (3) selecting from menus provided by the On Screen Display (OSD). A powerful Auto Scan feature also permits automatic scanning and monitoring of the activities of all computers running on the installation one by one.

A KH98 installation: (1) eliminates the expense of having to purchase a separate keyboard, monitor, and mouse for each computer; (2) saves all the space those extra components would take up; (3) saves on energy costs; (4) eliminates constantly moving from one computer to another; and (5) cuts down Cost of Ownership by preventing system failure and reducing downtime.

1. Port LEDs

The Port LEDs on the left are the On Line LEDs; the ones to the right are the Selected Port LEDs:

 The On Line LEDs light GREEN to indicate that the computer attached

to the corresponding port is up and running. If the LED is flashing, it indicates that the Port is being used for cascading to another KH98 switch (see Two Stage Installation, page 10).

 The Selected LEDs light ORANGE to indicate that the computer

attached to the corresponding port is the one that has the KVM focus. The LED is steady under normal conditions, but flashes when its port is accessed under Auto Scan Mode (see F7 SCAN, page 34).

2. Port Selection Switches

Press a switch to access the computer attached to the corresponding port.  Pressing Buttons 1 and 2 simultaneously for 3 seconds performs a

Keyboard and Mouse Reset.

 Pressing 7 and 8 simultaneously starts Auto Scan Mode (see page 34).

3. Reset

Use a thin object (such as the end of a paper clip, or a ballpoint pen), to press this recessed switch in to initiate a reset.

Hardware Setup

Installation

1. Important safety information regarding the placement of this device is provided on page iv. Please review it before proceeding.

2. Make sure that power to all the devices you will be connecting up have been turned off. You must unplug the power cords of any computers that have the Keyboard Power On function.

Single Stage Installation

In a Single Stage installation, there are no additional KH98's cascaded down from the first unit. To set up a single stage installation refer to the diagram below (the numbers in the diagram correspond with the numbers of the instruction steps), and do the following:

1. Plug your keyboard, mouse, and monitor into the unit's Console Ports.

2. Use KVM cable sets (as described in the Cables section on page 3), to connect any available KH98 KVM Port to the Keyboard, Video and Mouse ports of the computer you are installing.

3. Plug the Cat 5 cable that connects the KH98 to the IPMI Management LAN. (This step is optional, see note below).

Note: This step is only applicable to IPMI installations. Only the first

KH98 unit should be connected to the IPMI Management LAN. See picture below.

4. Plug the power cord that came with this package into the KH98's Power Socket, and then into an AC power source.

5. Power on the monitor.

6. Power on the KH98.

Two Stage Installation

To control and monitor more computers, up to eight additional KH98 units can be cascaded from the KVM ports of the First Stage unit. The cascaded KH98 units that connect back to the First Stage unit are considered Second Stage units.

As many as 64 computers can be controlled in a complete two stage installation. A table showing the relation between the number of computers and the number of KH98 units needed to control them is provided on page 51.

Note: 1. Mixing different KVM switch models on the same installation can

cause problems with OSD port switching. We strongly recommend that all cascaded units be the same model as the First Stage unit.

2. If you are adding this switch into an already existing KH98 configuration, be sure to make it the First Stage unit. Otherwise, you won't get the benefit of its improved OSD features and functions.

To set up a Two Stage installation, do the following:

1. Complete a Single Stage installation. See page 9 for details.

2. Turn off the power to all the devices you will be connecting up, including all devices on the Single Stage installation.

3. Use a KVM cable set (described in the Cables section, page 3), to connect any available KVM Port on the First Stage unit to the Console Port connectors of the Second Stage unit.
