Monitor Port

Plug in the monitor for your local console on the switch.

PC-USB Port

This provides USB keyboard/mouse connections (USB Type B) to a USB-enabled PC or to a USB KVM switch. Thus, if you are connecting any USB-enabled PC or USB KVM switch, use a USB cable to make the connection.

Ethernet Port

This digital port (RJ-45) offers anytime/anywhere access to the Digital KVM over IP Switch and, subsequently, the conventional KVM switch(es) and servers/computers connected behind it to the remote login clients over the LAN/Internet.

Serial Control Port

Connect to either an external modem or a power control unit (or to a cascaded chain of power control units). When an external modem is added to its serial control port (RJ-12), the switch could serve either as a PPP server to allow direct cable connection or dial-in connection from its peer computers, or as a PPP client to dial out to an ISP or Enterprise PPP server. Furthermore, through serial commands sent over its serial control port, the switch can perform remote

installation

Digital KVM over IP Switch Setup

1.Plug the included power adapter into the Digital KVM over IP Switch and an AC source, then turn on the switch.

2.Set up your local console by connecting a PS/2 keyboard, mouse and monitor to the proper keyboard, mouse and monitor ports on the switch (see Front and Rear Panel above).

3.Connect to one or more computers/servers as described below:

Single Server Mode (see Page 5 configuration image): To connect to just one server or computer, simply connect the PC/KVM port on the back panel of the Digital KVM over IP Switch to the server/computer using the included 3-in-1 combo cable (HDB-15 male to HDB-15 male and 2 mini-DIN 6s) and/or a USB cable (if/as needed).

Multiple Server Mode (see Page 6 configuration image): To connect to multiple servers/ computers, add a conventional KVM switch to the configuration by connecting to the PC/

KVM port or the console port of your Digital KVM over IP Switch using the included 3-in-1 combo cable (HDB-15 male to HDB-15 male and 2 mini-DIN 6s) and/or a USB cable (if/ as needed). The added KVM switch is then connected to the multiple computers/servers.

Server Configuration

Mouse Acceleration

Mouse acceleration is not supported by the Digital KVM over IP Switch, so any such function

(including any “Snap To” option) needs to be deactivated on all connected servers.

Windows XP:

Go to the Mouse Control Panel, select the

Mouse Properties tab, then go to the Pointer

Options screen.

1.Set the pointer speed slide bar to the exact middle.

2.Uncheck the “Enhance pointer precision” option.

3.Uncheck the “Automatically move pointer to the default button in a dialog box” option.

4.Click “OK.”

INSTALLATION

Windows 2000:

Go to the Mouse Control Panel, select the Mouse Properties tab, then go to the

Pointer Options screen.

1.Set the pointer speed slide bar to the exact middle.

2.In the Acceleration panel, select “None.”

3.Uncheck the “Move pointer to the default button in dialog boxes” option.

4.Click “OK.”

Windows 98:

Go to the Mouse Control Panel, select the Mouse Properties tab, then go to the

Motion screen.

1.Set the pointer speed slide bar to

“Slow” (all the way to the left).

2.Click “OK.”

NOTE: As shown above, mouse settings differ depending on the operating platform; some presenting mouse acceleration options, some not. If you see any mouse acceleration option, uncheck (deactivate) it. If there is no mouse acceleration available on the Settings screen, adjust the mouse speed slide bar either to x1 or the slowest position (such as on Linux platforms). In some cases, a middle position on the speed slide bar may be required for mouse synchronization on the viewer side (as with Windows XP, for example); or a bit of trial-and-error configuring may be necessary to set your mouse acceleration to Off and the speed to x1.

Additional Server Configuration Considerations

For optimal performance of the Digital KVM over IP Switch and whatever devices it’s connected to, keep these configuration points in mind for networked computers and servers.

Select resolution modes that are within the switch’s standard support parameters:

10 INSTALLATION

The Digital KVM over IP Switch supports most display modes up to 1600 x 1200. However, you might encounter some display problems when your display card is outputting an unusual display mode, such as no video or an abnormal screen display. To simplify the display factor before connection to the switch, it’s recommended that more standard display modes be used (see

Disable special transition effects on the screen outputs of your connected servers:

Go to Control Panel Display Appearance Effects. Uncheck any of the selected options (as needed) in order to disable transition effects such as Fade for the menus and tool tips. Perform this same operation on each of your connected servers. NOTE: On platforms such as Windows 98, 2000, XP and Server 2003, some transition effects might yield undesirable video refreshing artifacts, especially when you are using “Medium” or

“Low Video Quality” as your video filter settings. To prevent undesirable artifacts from appearing on your screen, deselect the special transition effects.

Choose plain and solid server desktop backgrounds for your connected servers:

To optimize the bandwidth efficiency and speed up video performance across the bandwidth-limited environment, it’s recommended that you select a relatively plain server desktop: solid colors or lightcolored graphics. Complex patterns or color gradients should be avoided if bandwidth is critical in your application, as they will create more bandwidth demands for their transmission across the Internet.

chart at left). NOTE: These are suggested display modes for server desktops; however, actual feasible display modes for any particular server desktop will be dependent on its display card. (That is, some display modes listed in the chart might not be feasible with some display cards, and a trial- and-error approach may be more useful in determining the best display mode.)

INSTALLATION 11

Network Settings

1.Connect the Digital KVM over IP Switch to the Ethernet LAN. The factory default network settings for the switch:

IP address: 192.168.1.200

Net mask: 255.255.255.0

Gateway: 192.168.1.254

DNS: 192.168.1.254

2.Access the switch’s Web Management interface by entering the following in the address bar of your browser window on a remote client: https://192.168.1.200:5908.

3.A login prompt displays for the account name (username) and the password. Use the defaults:

Username: superuser

Password: superu

After logging in, you will see the KLE Web Management interface. NOTE: KLE, or KVM Link Extender, is another name for the Digital KVM over IP Switch, and appears on many of the screen images.

4.Go to the LAN TCP/IP page on the switch’s Web Management interface and modify your IP settings. (Refer to Unit Management over a Secure HTTPS Browser Connection / Main /

TCP/IP Settings – Port and IP Settings.)

5.Click “Apply Settings.”

6.Verify the switch’s network connection by connecting to the switch through the Web

Management interface using the new IP address. NOTE: The IP address should be followed immediately by a colon and the port base +8 for the port number:

https://<IP_address>:<PortBase+8>

For example, if the IP address is 192.168.1.7 and the port base number is 5900, then you should enter https://192.168.1.7:5908. IMPORTANT: Remember that it’s a secure SSLencrypted connection, so enter “https” instead of the usual “http.” Otherwise, the connection won’t be established.

12 INSTALLATION

Port Base Settings

NOTE: If you’re satisfied with the default port base setting as 5900, you can skip this section.

The default port base for switch connection is set at 5900. This means it will use port 5900 (port base) for viewer connection and port 5908 (port base + 8) for https Web browser connection.

for viewer connection: <Port base>

for secure browser connection: <Port base + 8>

However, if you intend to use your own port base setting, just access the Web Management interface and configure the port base as follows:

For example, if you choose 5970 as your port base, then you have:

for viewer connection: 5970

for secure browser connection: 5978

Template – Windows Internet Explorer

https://192.168.1.200.5978

Click “Submit” and “Apply Settings” to validate the new settings. The switch is now installed within your LAN, and you’re able to proceed with establishing a remote viewer connection.

INSTALLATION 13

Configuration of the Firewall/Router for Access across the Internet

To allow access to the Digital KVM over IP Switch behind a corporate firewall/router, establish the following settings on your firewall/router (not on your switch).

1.Configure a virtual server on your router (or ask your network administrator to do it) as mapped to the switch’s local IP address.

2.Open a port range (<port_base> – <port_base_+_9>) both inbound and outbound for the virtual server according to what has been previously configured as the port base for the switch.

As per the previous example, if the switch is configured with a port base of 5970, then the port range should be opened as 5970–5979 (i.e., <port_base> – <port_base +9>) both for inbound and outbound, in which:

for the switch’s viewer connection port: <port_base> = 5970

for the browser SSL connection port: <port_base + 8> = 5978

for viewer internal communication, etc.: <port_base + 9> = 5979

Example: Router Internet IP ‡‡ virtual server (port range open) ‡‡ switch’s local IP 61.232.134.120 ‡‡virtual server (port 5970–5979 open) ‡‡192.168.1.7

Once you’ve configured a virtual server with an appropriate port range open (<port_base> – <port_base_+_9>), you can try to access your switch across the Internet by using a public IP address and designated port number. Based on the previous example settings:

Browser access: https:// 61.232.134.120:5978

Viewer access: 61.232.134.120:5970

If you have domain name mapping to the public IP address, you can also use the domain name; for example:

Browser access: https:// www.mycompany.com:5978

Viewer access: www.mycompany.com:5970

NOTE: Once you’ve changed the port base of your switch, you should also modify the open port range on your router accordingly if you want Internet access to come across.

Installation of Certificates

NOTE: You can use the default set of certificates (on the included CD) to practice making some PKI-authenticated connections as long as your network safety isn’t jeopardized. It’s recommended that this be done within your local area network, assuming it’s well secured with an adequate firewall and other due precautions against network intrusions. Otherwise, anyone who has a copy of the default certificates can establish a connection to your servers. If you have already obtained a set of certificates with the file names and formats required for the switch (which is strongly recommended), you can use them for viewer authentication. You can also generate the certificates using software like XCA. (For certificate generation using XCA, refer to “How to Generate KLE Certificates Using XCA” on the included CD.)

First, you need to have these certificates — as mentioned above, if you haven’t obtained your own certificates, you can use the default set of certificates — ready on your client computers for uploading to the switch via a Web browser:

root certificate (root.crt)

server certificate (server.crt), and

server private key (serverkey.pem)

Once you’ve located whichever set of certificates is to be used, you can begin the installation process.

1. Access the switch’s Web Management interface and go to the Security Settings screen.

14 INSTALLATION

2.Click “Browse” and use the “Choose File” dialog box to browse and locate your certificate files.

3.Click “Upload” on the Security Settings screen to upload the root certificate to the switch. When the upload is completed, the prompt page for rebooting will display.

4.Click “Reboot.” Once the switch has booted back up, continue with the import of the server.crt and the serverkey.pem files.

NOTE: You don’t need to reboot each time you finish uploading a certificate: You can do one complete reboot after you finish uploading all of them. To return to the previous Security Settings screen to upload another certificate without immediately going to a reboot, just click

“Security Settings” on the left side of the screen.

INSTALLATION 15

Selection of a Security Level for Viewer Connection

1.Go to the Security Settings screen on the switch’s Web Management interface and make a viewer connection selection from the “Security Level” drop-down menu.

Level 1: No encryption (no SSL)

Level 2: 256-bit encryption, no user certificate required for user authentication

Level 3: 256-bit encryption, user certificate required for authentication (PKI)

Security Level 1 offers a non-secured connection, and hence should be used with caution when the switch is intended to be accessed through an external network. For Level 1, there’s virtually no encryption.

Security Level 2 offers a secured SSL connection that provides encryption for mouse, keyboard and video but uses no PKI authentication.

Security Level 3 offers a secured SSL connection that provides encryption for mouse, keyboard and video, and uses 1024-bit PKI authentication.

IMPORTANT: The selection of a security level to be implemented for the switch’s viewer connection is of utmost importance, especially when your remote server connections require a high level of security in order to keep your servers safe from unauthorized entry and/or network sniffers.

2.(Optional) If you choose to implement the PKI authentication feature on the switch’s viewer, you need to select Level 3 security in the Viewer Connection panel on the Security Settings screen of your Web Management interface.

Then enter the password in the “KVM Server Password” field. NOTE: You should enter the password that has encrypted the server private key in the server private key file (serverkey.pem)

16 INSTALLATION

in order to make a successful viewer connection with the switch in the Level 3 security setting.

If you use the standard set of certificates provided on the included support CD, the password that encrypts the server private key is “serverpwd.” However, if you use your own set of certificates, you should get the correct server password from the Certificate Authority that issued those certificates.

3. Go to the Apply Settings screen and click “Restart Servers” to validate your selection.

Selection of a User Password Policy

1.On the Security Settings screen, select one of three options from the “User Password Policy” drop-down menu.

No Password

Global Password

User Password

If you select “No Password,” anyone can establish a connection without entering a valid password.

If you select “Global Password,” the viewer will prompt you for a global password, which is used by all who want to make a viewer connection to the switch.

If you select “User Password,” the viewer will prompt you for a user-specific password. With this setting, each login user will be checked against his or her corresponding password before being allowed a viewer connection.

2. Go to the Apply Settings screen and click “Restart Servers” to validate your selection..

NOTE: In all, there are nine (3 x 3) possible combinations of Viewer Security Levels / Password Policies, allowing administrators to choose the pairing that best suits their particular needs.

G=GlobalPassword U=User-specificPassword S=256-bitSSLEncryption P=1024-bitPKIAuthentication N=Notavailable

IMPORTANT: User Password Policy and Security Level (SSL/PKI Authentication) settings should be used with caution: If you adopt No Password Policy and No SSL Encryption / No SSL Authentication, anyone with a viewer and knowledge of the access IP and port number of the switch can establish a remote connection.

At this point, your Digital KVM over IP Switch is ready for a PKI-authenticated plus SSL-encrypted viewer connection! All you need to do is to distribute the following to your remote connection client(s):

Certificates (obtained from your Certification Authority and required only if you selected

Level 3 viewer security)

Certificate password (obtained from your Certification Authority and required only if you selected Level 3 viewer security; if using the default set of certificates, use “clientpwd”)

Username and password (specified on the Web Management interface/screen and required only if you chose the User Password option; if using defaults, use the username/ password combinations Superuser/superu, Admin/123456 or User/123456)

Global Password (as specified on the Security Settings screen and required only if you chose the Global Password option)

INSTALLATION 17

viewer connection

The Digital KVM over IP Switch provides a Win32 viewer for Windows users and a Java viewer for cross-platform use on any major operating system.

Installation of a Win32 Viewer

Go to the Download screen to download the Win32 viewer (Kripview_install.exe).

Install the viewer program on the client computer that will connect to the switch.

After installation, a KLE icon (right) will be created on your client desktop.

Installation of a Java Viewer

Before you can use the Java viewer (KViewer.jar) on any OS platform, you should first install the Java Runtime Environment, JRE 1.5.0 or higher, which can be downloaded from www.java.com. To download the Java viewer, just go to the

Download screen of the Web Management interface. NOTE: To run the small Java program, you don’t have to actually save the Kviewer.jar file to your local hard drive since it isn’t that big (only 70 kB): You can open it directly. Note

also that on some client platforms — such as Linux — after you have installed the JRE file on your client platform, you need to set the path information in order for the client system to know where the Java compiler program is.

18

VIEWER CONNECTION

 

Importing Certificates to a Viewer on a Client Computer

NOTE: If you will be using only the non-PKI-authenticated viewer connections to the switch (such as Level 1 – no encryption/authentication or Level 2 – 256-bit SSL encryption and only server authentication by client), you are not obliged to use or import any certificates and you can skip this section.

To make a fully PKI-authenticated viewer connection with the Digital KVM over IP Switch, you need to import client certificates to the Win32 viewer and Java viewer on the client computer. A default set of certificates is provided on the enclosed CD, or you can use your own set of certificates. If using your own, in addition to importing the client certificates to the Win32/Java viewer on the remote client computer(s), you should import the root certificate, the server certificate and the server private key to the switch on the Web Management interface Security Settings screen. (Refer to Main/Security – Certificate Installation, Viewer Encryption and Password Policies in the next section.)

The file names of the client certificates can vary (client_name1.p12, client_name2.p12, etc.), but the certificates and private key for the switch remain as they are (root.crt, server.crt, serverkey.pem). The client certificates should be imported in the .p12 format, using the import utility of whichever viewer (Win32 or Java) is on the client computer. NOTE: Make sure you have the certificates ready for import, either on a transfer device or the local computer hard drive. If you copy certificates to the local hard drive, you may need to delete them after finishing the import so others won’t have access to the certificate files. Even though they’re passwordprotected, one can never be too careful. Remember, too, that the Win32 and Java viewers require separate certificate import utilities.

Import a Client Certificate to a Win32 Viewer

Go to Start Programs PROSUM

KLE Viewer Import Certificates. Click “Root Certificate” to import the root certificate; click “Client Certificate” to import the client certificate. When the

“successfully imported” message appears in the text field, click “Exit” to proceed.

Import a Client Certificate to a Java Viewer

Go to Start Programs PROSUM

KLE Viewer Import Certificates. Click “Root Certificate” to import the root certificate; click “Client Certificate” to import the client certificate. When the
