Introduction

Overview

The KM0832 Matrix KVM Switch gives IT administrators advanced control of multiple computers. Operators working at up to 8 keyboard, monitor, and mouse (KVM) consoles can independently and simultaneously take direct control of up to 32 computers. Using ATEN’s advanced video routing technology, users can separately access up to 8,000 KVM ports in cascaded KM0832 at the same time.

The 8 KVM consoles belonging to the first-level KM0832 are able to access all the computers on the installation – those that are directly connected as well as those that are daisy-chained and cascaded. The 4 or 2 KVM consoles belonging to each daisy-chained KM0432 or KM0216 Matrix KVM Switch can access the computers that are connected to them on the same daisy-chain level.

The KM0832 allows both PS/2 and USB KVM consoles to control PS/2, USB, Sun, Mac, and serial devices. The KM0832 uses Cat 5 cables to send and receive signals up to 300 meters between console modules and KVM adapter cables, while Auto Signal Compensation (ASC) helps maintain high video resolution. In addition, use of RJ-45 connectors saves precious IT real estate by allowing a full 8 user ports and 32 KVM ports to reside in a single 1U housing.

Setup is fast and easy—plugging cables into their appropriate ports is all that is entailed. Because the KM0832 intercepts keyboard and mouse input directly, there is no software to configure, so there is no need to get involved in complex installation routines or be concerned with incompatibility problems.

The Web-based KM0832 Administrator Utility allows users to configure the KVM installation, account settings, and user access from anywhere, anytime. Access to any computer is easily accomplished either by means of a powerful menu-driven On Screen Display (OSD) system, or by entering Hotkey combinations from the keyboard. A convenient Auto Scan feature also permits automatic scanning and monitoring of the activities of all computers running on the installation one-by-one.

Multilevel Installations

You can greatly expand the number of computers that can be added to your installation by performing a multilevel installation. The KM0832 supports two types of multilevel installation:

 Cascading  Daisy-chaining

Overview

Cascading involves using the KVM port(s) of a parent KVM switch (one that is above a KVM switch linked down from it) to connect to the user ports of a child KVM switch.

Daisy-chaining refers to adding a KVM switch via a dedicated daisy-chain port (see the diagram on page 27). When daisy-chaining KM0432 or KM0216 Matrix KVM Switches, KVM Ports 1–4 on the first-level KM0832 will be unusable. Neither computers nor cascaded KVM switches can be connected to these KVM ports.

The KM0832 supports both daisy-chaining and cascading, providing enormous capacity and flexibility to expand the installation. The following sections provide information and procedures to set up cascaded and daisy-chained KVM installations.

Note: If the daisy-chain feature is not operative on your unit, you will need a

newer version of the firmware. Contact your dealer for details.

Chapter 2. Hardware Setup

Cascading

The KM0832 supports cascading up to 3 levels of KM0832 and 1 level of KVM switches other than the KM0832 (see Supported KVM Switches, page 137). However, no matter how many levels of KM0832 are cascaded, you can only cascade 1 level of other KVM switches. After cascading a KVM switch other than the KM0832, you cannot cascade any more child KVM switches from the non-KM0832 switch.

Compatible KVM switches allow all of the separate switch OSDs to be integrated so that when the first level KM0832 consoles bring up the OSD, the port directory lists all of the computers connected to all of the cascaded switches.

In cascaded installations, the number of bus connections between a parent and child KVM switch determines the number of users that can simultaneously access the KVM ports of a child KVM switch. A bus connection is established by connecting a KVM port on the parent KVM switch to a user port on the child KVM switch. The KM0832 supports a maximum of eight bus connections for each cascaded KM0832, and usually no more than one for other KVM switches.

In order for all eight KVM consoles on the first-level KM0832 to be able to access the KVM ports of a cascaded KM0832 at the same time, you must create eight bus connections between the first-level KVM switch and the child KVM switch. If the two KVM switches are not directly connected, the intermediary KVM switch(es) must have eight bus connections to the parent and child KVM switches.

KVM consoles connected to the user ports of a cascaded KVM switch can access KVM ports on the same level, or those of cascaded child switches, but cannot access KVM ports of parent switch(es).

KM0832 User Manual

Cascading KM0832 Matrix KVM Switches

To cascade KM0832 Matrix KVM Switches (refer to the installation diagram on page 21):

Note: Before cascading additional KM0832, ensure that the firmware version

of the KM0832 to be installed matches that of the first-level KM0832. Otherwise, they may be incompatible.

1. Connect the KVM console to the console module. Plug the keyboard, mouse, and monitor into the ports on the console

module. Each port is marked with an identifying icon.

2. Connect the console module to the KM0832. Use Cat 5 cable to connect the Link port of the console module to one of

the user ports on the KM0832's rear panel. (Repeat steps 1 and 2 for all KVM consoles that you wish to connect. Up

to 8 KVM consoles may be connected in this fashion.)

Note: The distance between any console module and any KVM adapter

cable, or the first-level and last-level KVM switches, cannot exceed 300 m (1000').

3. Use Cat 5 cable to connect up to eight KVM ports on the first-level KVM switch to the user ports on the second-level KVM switch. (The number of KVM consoles on the first-level KM0832 that can simultaneously access the cascaded KVM switch is limited by the number of connections between the parent and child KVM switches.)

(Repeat step 3 for each second-level KVM switch that you wish to cascade. If you wish to cascade any third-level KVM switches, follow the instructions in step 3 when cascading them from the second-level KVM switches.)

Note: The maximum distance between any two KM0832 cannot exceed

150 m.

KM0832 User Manual

Cascading Other KVM Switches

When cascading KVM switches other than the KM0832, a KVM adapter cable is required. The KVM adapter cable converts the KVM port connector used by the KM0832 to connectors appropriate for the KVM switch that you are installing. Refer to the table on page 5 that lists the KVM adapter cables and the platforms that they support.

Note: Only 1 non-KM0832 KVM switch can be cascaded from each KVM

port, regardless of its position in the installation. After cascading a nonKM0832 KVM switch, you cannot cascade any more KVM switches from it.

To cascade a KVM switch other than the KM0832:

1. Use a Cat 5 cable to connect a KVM port on the KM0832 to the KVM adapter cable.

2. Connect the cables on the KVM adapter cable to the console ports on the KVM switch you are installing.

Daisy-chaining

Up to 7 KM0432 or KM0216 Matrix KVM Switches can be daisy-chained to the first-level KM0832. When daisy chained with the KM0432 or KM0216, the KM0832 must occupy the master (first-level) position, while the KM0432 or KM0216 must be used as the slave KVM switch(es) (those KVM switches daisy-chained from the master KVM switch).

When daisy-chaining KM0432 or KM0216, KVM Ports 1–4 on the first-level KM0832 will be unusable. Neither computers nor cascaded KVM switches can be connected to these KVM ports.

The KM0832 is capable of supporting eight independent KVM consoles, while each KM0432 or KM0216 is capable of supporting 4 or 2 independent KVM consoles. In a complete daisy-chained installation, the eight KVM consoles that belong to the KM0832 can access and control all of the computers on the installation. The 4 or 2 KVM consoles belonging to each slave KM0432 or KM0216 KVM switch only control the computers connected to their respective KVM switches.

Note: If the daisy-chain feature is not operative on your unit, you will need a

newer version of the firmware. Contact your dealer for details.

To set up a daisy-chained installation, refer to the diagram on page 27 and do the following:

1. Use a daisy-chain cable set (described in Cables, page 5) to connect the

CHAIN OUT port of the first-level KM0832 to the CHAIN IN port of the slave KM0432 or KM0216 (first station out to second station in, second station out to third station in, etc.).

Note: 1. When daisy-chained with the KM0432 or KM0216, the KM0832

must occupy the first-level (master) position, while the KM0432 or KM0216 must be used as the slave station(s).

2. The maximum distance between any two KM0432 or KM0216 cannot exceed 10 m.

3. The maximum distance between the first-level KM0832 and the last KM0432 or KM0216 in the daisy-chain cannot exceed 20 m.

3. Plug the power cords into an AC power source and into the power sockets on the KM0832 and KM0432 or KM0216.

4. Power on the installation according to the following procedure: a) Power on the first-level KVM switch (KM0832). Wait one minute for

the KVM switch to ascertain its position. (The KM0832 does not have a station ID because it always occupies the first station position.)

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

then third station, etc.). In each case, wait for the position to be ascertained and displayed on the current station ID before powering on the next station. (The ID for the second-level KVM switch is 02, the ID for the third-level KVM switch is 03, etc.)

c) After all the KVM switches are powered on, power on the computers.

The use of RJ-45 KVM port connectors, combined with Auto Signal Compensation (ASC), allow signals to travel up to 300 meters (1000 feet) and still maintain reliability and high video resolution. This allows the KM0832 installation to take advantage of the internal Cat 5e and Cat 6 wiring built-in to most modern commercial buildings.

Since the data signals are not transmitted in packets, the transmission cannot go through network hubs or switches. Passive components such as patch panels, keystone jacks, patch cables, etc. can be used to channel the traffic, instead.

Chapter 3

Basic Operation

Hot Plugging

The KM0832 supports hot plugging – components can be removed and added back into the installation by unplugging their cables from the ports without the need to shut down the KVM switch. In order f or hot plugging to work prop erly, however, the procedures described below must be followed:

Switching Daisy-chained KVM Switch Positions

You can switch the position of daisy-chained KM0432 or KM0216 by simply unplugging from the old master KVM switch and plugging into a new one.

Switching Cascaded KVM Switch Positions

You can switch the position of cascaded KM0832 by simply unplugging from the old parent KVM switch and plugging into a new one. The station names and port notes are automatically synchronized with the new position in the installation.

Cascaded non-KM0832 also can be hot plugged; however, port notes are not automatically synchronized. You will need to manually update port notes after changing the position of either cascaded non-KM0832 or attached computers.

Hot Plugging User Ports

The keyboard, monitor, and mouse all can be hot plugged. If you experience a problem after you plug in a new mouse, do a system reset by pressing the reset button on the KM0832's front panel (see page 6 for details). If this doesn't resolve the problem, restart the computers that have the problem.

KM0832 User Manual

Powering Off and Restarting

Powering off the KM0832 does not affect the computers attached to it. When you restart the KM0832, you will regain control immediately. To replace a KM0832, simply power it down, unplug the cables, plug them into the new KVM switch, and power the new KVM switch on.

Note: If any of the computers behave strangely after powering off and

restarting, or changing a KVM switch, simply restart the computer.

Port Selection

Port selection is accomplished either by means of the KM0832's OSD or by entering Hotkey combinations from the keyboard. OSD operation is discussed in detail in Chapter 5; hotkey port selection is discussed in Chapter 6.

Although hotkeys are handy for a single level installation, we strongly recommend you use the more powerful and versatile OSD – especially for cascaded and daisy-chained installations.

Chapter 4

Administrator Utility

Overview

The KM0832 Administrator Utility enables network administrators to securely manage the KM0832 Matrix KVM Switch from anywhere in the world at anytime. Super administrators can manage users and groups, control port access, upgrade firmware versions, and perform many other administrative functions using the intuitive and easy-to-use menus and icons. The KM0832 Administrator Utility is browser-based and does not require any software to be installed on either client computers or servers.

The KM0832 Administrator Utility offers simultaneous access for up to 16 administrators and users. Up to seven users at a time can configure settings in the KM0832, while one user at a time can configure settings in daisy-chained KM0432 or KM0216. Security is maintained by a powerful combination of user password authentication, three-level user access control, and port restrictions. These ensure that unauthorized users cannot gain control of your mission-critical servers.

The KM0832 Administrator Utility’s integrated tree view pro vides seaml ess navigation of daisy-chained and cascaded KVM switches. Root station configurations are automatically synchronized with all cascaded KM0832 Matrix KVM Switches.

Most features of the KM0832 Administrator Utility are also available from the text-based OSD. Changes made in the KM0832 Administrator Utility are reflected in the text-based OSD and vice-versa.

This chapter describes how to configure the KM0832, set up user and group accounts, configure KVM ports, upgrade firmware, and perform other administrative functions.

KM0832 User Manual

Setting the IP Address

You can use a Web browser, the IP Installer, or the OSD to configure the KM0832 for deployment on your local network. Or, you can assign an IP address from the command line. To use a Web browser to configure the KM0832 you will need: (1) a computer equipped with a Web browser, (2) an Ethernet hub with at least 2 ports, and (3) 2 Cat 5 cables.

To configure the network settings via a Web browser:

1. Plug one end of a Cat 5 cable into the Ethernet hub and the other end into the CONFIGURATION port on the rear panel of the KM0832.

2. Plug one end of a Cat 5 cable into the Ethernet hub and the other end into the network adapter of a computer equipped with a Web browser.

3. Make sure that the computer’s IP address lies within the same subunit as that of the KM0832. (The default IP address for the KM0832 is

192.168.0.10.) Set the IP address for the computer’s network adapter to

192.168.0.XXX, where XXX represents any value from 1–254 (except 10 and 254, which are reserved for the KM0832). (See Factory Default Settings, page 132, for a list of the KM0832’s default network settings.)

Note: If you are using a proxy server, you might need to modify your

computer’s proxy server settings before accessing the KM0832.

4. Enter 192.168.0.10 in your Web browser’s address bar. The KM0832 Login Webpage appears.

5. After logging in, assign an IP address that is appropriate for your local network to the KM0832. (See Network Configuration, page 42).

6. After logging out, restore your computer's network adapter settings back to their original values.

To configure the network settings via the IP Installer: Go to the ATEN homepage and select the Webpage that is specific for the

KM0832. From there you can download the IP Installer along with instructions on how to use it to assign an IP address to the KM0832.

Chapter 4. Administrator Utility

Managing Port Access Rights for Groups

Super administrators can manage KVM port access rights for groups from the Group Information Webpage.

Note: You do not need to assign access rights for a group to any KVM port

that cascades a KM0832. However, you must assign access rights to KVM ports that cascade non-KM0832 KVM switches. When you assign access rights to a KVM port that cascades a non-KM0832 KVM switch or Matrix Plus KVM adapter cable, the access rights apply to all KVM adapter cables in the cascade. This also applies to daisy-chained KM0216 and KM0432 switches.

User Management

Up to 1023 user accounts can be added to the KM0832 with no restriction on the number of any user type. Each user requires a unique user account to access the KM0832 through a KVM console or through the KM0832 Administrator Utility. Super administrators can add, modify, and delete all user types, while administrators can add, modify, and delete only other administrators and users. (An additional default super administrator account cannot be modified or deleted.) Super administrators also can log in to the KM0832 Administrator Utility when all normal sessions are in use and close the session of another user.

The KM0832 requires each user to be added to a group; therefore, we suggest that you create groups before users. If you do not wish to create groups you may add users to the default group account. However, the default group account cannot be used to grant KVM port access to group members. In this case, you will need to individually add users to the KVM ports.

The User Management Webpage is similar to the Group Management Webpage. It shows all users that have been created on the KM0832 and their individual group memberships. I t also provides options for creating new users and modifying or deleting existing users.

Port Management

KM0832 port access rights for users and groups are set on a port-by-port basis, giving administrators a high degree of control over which KVM ports users can access and how they access the KVM ports. To enable users to access KVM ports, you must first configure the user access rights for each KVM port. By default, all super administrators and administrators have full access to all KVM ports.

Note: Adding users to groups streamlines KVM port configuration by

allowing you to assign port access to whole groups of users at one time.

In this section we will discuss how to:

 Set port access rights for users and groups  Configure KVM port settings and assign names to KVM ports  Restore KVM port defaults

This also is true for KVM ports in cascaded child stations. (To add users to ports directly from the User Information page, see Managing Port Access Rights for Users, page 59. To add groups to ports directly from the Group Information page, see Managing Port Access Rights for Groups, page 51.)

To open the Port Management Webpage for a KVM port:

1. If you are not logged in to the KM0832 Administrator Utility, open the KM0832 Login page and log in. The KM0832 Administrator Utility Main Screen will appear.

2. In the KM0832 tree (on the left side of the Main Webpage), click on a computer icon. Each computer icon corresponds to a KM0832 KVM port. The Port Management Webpage for that KVM port appears. (See page 38 for more information about using the computer icons.)

-orOpen the Port Select Webpage. Go to step 3.

Chapter 4. Administrator Utility

3. In the Port ID column, click on a port ID to open the Port Management

Webpage for that KVM port. The Port Management Webpage appears.

Note: For daisy-chained KM0216 and KM0432, only the Port Settings area of

the webpage displays. Daisy-chained KM0216 and KM0432 cannot have their ports managed individually. Access to the entire chain is controlled under Group Management (see page 47) and User Management (see page 53).

KM0832 User Manual

The Port Access area of the Port Management Webpage is used to manage port access rights for users and groups. The boxes on the left side of the Webpage show all users and groups that have been created. The boxes on the right side of the Webpage govern port access rights.

In the middle of the Webpage are five sets of arrows. Each set contains two arrows, one facing leftward (<) and the other facing rightward (>), which correspond to the boxes immediately to the left and right. Arrows are used to move users and groups from the boxes on the left into the boxes on the right and vice versa.

(Continued from previous page.)

Repeat Steps 2 and 3 until you have assigned port access rights (or restrictions) for all users and groups.

If you make a mistake by adding a user or group to the wrong access rights box, simply highlight the username (or group name) again and then click the corresponding leftward facing arrow. The selected user (or group) is removed from the box and put back into its former position.

4. Click Save. The selected users (or groups) are given the permissions that

were assigned in the last step.

Cascaded Installations

Super administrators and administrators have full access to all KVM ports in the installation. You must assign access rights to KVM ports for all other users and groups. You do not need to assign access rights for users and groups to any KVM port that cascades a KM0832. However, you must assign access rights to KVM ports that cascade non-KM0832 KVM switches. When you assign access rights to a KVM port that cascades a Matrix Plus KVM adapter cable, the access rights apply to all KVM adapter cables in the chain.

Configuring Port Settings

Before you configure port settings, first verify that the KVM adapter cable for the KVM port you wish to configure is connected to the correct KVM port on the back panel of the KM0832. The fields in the lower section of the Port Management Webpage are described in the table on the following page.

Chapter 4. Administrator Utility

Field Description

Port Note Type a name in the Port Note field. Port notes may be up to 15

characters long. Legal characters include: a–z, A–Z, 0–9, space, and hyphen. Enter a unique note for the port that will differentiate it from all other ports in the KVM installation. The port note will appear on the Port Status and Port Select Webpages, in the KM0832 tree next to the computer icon, and in the OSD.

Note: Adding spaces to the port note will cause it to display on multiple lines in the tree in some Web browsers.

 If the KVM port cascades a KM0832, the port note is replaced by

the station name of the cascaded KM0832. To modify station names, see Naming Stations, page 40.

 If a non-KM0832 KVM switch or a computer is connected to the

KVM port by a KVM adapter cable, the port note can be changed. If the position of the KVM switch or the computer in the KVM installation ever changes, the port note for the new KVM port will automatically change to the port note stored in the KVM adapter cable. However, the port note for the old KVM port must be erased manually.

 If nothing is connected to the KVM port, the port note can be

changed. However, if a cascaded KVM switch or KVM adapter cable is attached to the port later, the port note will change to the port note stored in the KVM adapter cable.

Keyboard Layout (OS Language)

Keyboard (Port OS)

Set the layout of the keyboard(s) that will be used to access the computer attached to this port. The KM0832 supports 3 keyboard layouts: U.S. English, Japanese, and French. Configuring this setting correctly will ensure that characters are entered correctly and that the special keys on Japanese keyboards work correctly (if applicable).

Set the model of the keyboard(s) that will be used to access the computer attached to this port. The KM0832 supports 3 keyboard models: IBM PC (101/104 keys), Apple, and Sun. Configuring this setting correctly will ensure that the special keys on Apple and Sun keyboards work correctly (if applicable).
