Chapter 1

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.

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.

Setup Considerations

Hot Plugging

The KH98 supports hot plugging. Components can be removed and added back
into the installation by unplugging and replugging their cables from their
respective ports without the need to shut the switch down. For hot plugging to
work properly, the following procedures must be observed:

Hot Plugging KVM Ports:

When hot plugging cables from the KVM ports:

1. The cable must be plugged back into the same port it was removed from.

2. The mouse cable must be plugged in before the keyboard cable.

3. After plugging the cable back in, you must perform a KVM Reset on the
First Stage unit (by pressing the Reset switch In).

Hot Plugging Console Ports:

The unit supports hot plugging of the keyboard, monitor, and mouse. When hot
plugging the mouse from the KH98's console mouse port:

1. You may unplug the mouse and plug it back in again (to reset the mouse,
for example), as long as you use the same mouse.

2. If you plug in a different mouse, all the stations and all the computers on
the installation must be shut down for 10 seconds, then restarted. (Refer
back to the note describing the Power On sequence on p. 11, if necessary.)

Note: If, after hot plugging (or at any other time), there is no response to

mouse and/or PS/2 keyboard input, simultaneously press and hold Port
Select buttons 1 and 2 on the First Stage unit for 3 seconds to perform a
PS/2 Keyboard and PS/2 Mouse reset.

14

Chapter 2. Hardware Setup

Powering Off and Restarting

If it becomes necessary to Power Off one of the KH98 units, before starting it
back up you must do the following:

1. Shut down all the computers that are attached to the unit. If there are

stations cascaded down from it, all the cascaded stations and the
computers attached to them must be shut down, as well.

Note: 1. You must unplug the power cords of any computers that have the

Keyboard Power On function that are connected to the shut down
switches. Otherwise, the switches will still receive power from
the computers.

2. If the unit is operating under external power, unplug the power
adapter cable.

2. Wait 10 seconds, then plug the stations back in, starting with the lowest
stations in the chain and working back to the station you originally shut
down.

3. After all the KH98's are up, power On the computers, starting with the
ones attached to the lowest stations in the chain and working back to the
station you originally shut down.

KH98 User Manual

Port ID Numbering

Each KVM Port on a KH98 installation is assigned a unique Port ID. You can
directly access any computer on any level of the installation by specifying the
Port ID of the KVM port that the computer is connected to - either with the
Hotkey port selection method, or with the OSD.

The Port ID is a one, two, or three digit number. It is determined by the Stage
Level and KVM Port number of the KH98 unit that a computer is connected to.

The first digit represents the KVM Port nu mber of the First Stage unit; the
second digit represents the KVM Port number of the Second Stage unit; the
third digit represents the KVM Port number of the Third Stage unit.

 A computer attached to a First Stage unit has a one digit Port ID (from 1 -

8), that corresponds to the KVM Port number that the computer is

connected to.

 A computer attached to a Second Stage unit has a two digit Port ID.
 The first digit represents the KVM Port number on the First Stage unit that

the Second Stage unit links back to; the second digit represents the KVM
Port number on the Second Stage unit that the computer is connected to.

 For example, a Port ID of 2 3 refers to a computer that is connected to

KVM Port 3 of a Second Stage unit that links back to KVM Port 2 of the
First Stage unit.

 Likewise, a computer attached to a Third Stage unit has a three digit Port

ID. A Port ID of 2 4 1 refers to a computer that is connected to KVM Port
1 of a Third Stage unit, that links back to KVM Port 4 of a Second Stage
unit, which, in turn, links back to KVM Port 2 of the First Stage unit.

Chapter 2. Hardware Setup

Port Selection

The KH98 provides three methods to obtain instant access to any computer on
your installation: Manual, OSD, and Hotkey.

Manual:

Simply press the appropriate Port Selection Switch on the unit's front panel.
After you press the switch, the Selected LED lights to indicate that the port has
the KVM focus. The OSD (see page 19) autom a tically switches to highlight
the computer that you have selected.

Note: 1. On a cascaded installation, you must press the Port Selection switch

on the KH98 Station that connects directly to the computer you want
to access.

2. Simultaneously pressing Port Selection buttons 7 and 8 on the First
Stage unit initiates the Auto Scan feature (see F7 SCAN:, page 34), in
which all the ports currently selected for Quick View scanning
(see SET QUICK VIEW PORTS, page 28), are cycled through. The
length of time spent on each port is determined with the Scan
Duration setting under the OSD's F3 SET function (see page 24).

OSD:

OSD (On Screen Display), provides a menu driven interface to handle the
computer switching procedure to provide instant access to any computer on the
installation. OSD operation is discussed in detail beginning on page 19.

Hotkey:

Hotkeys allow you to conveniently provide KVM focus to a particular
computer from the keyboard, instead of having to manually select them by
pressing Port Selection switches. Hotkey operation is discussed in detail
beginning on page 37.
