5.4. Usage
Prerequisites
The U8/16-IP features an embedded operating system offering a variety of standardized
interfaces. This section will describe these interfaces, and the way to use them in a more
detailed manner. The interfaces are accessed using the TCP/IP protocol family.
The following interfaces are supported:
Telnet
A standard Telnet client can be used to access an arbitrary device connected to the U8/16-IP’s
serial port via a terminal.
HTTP/HTTPS
Full access is provided by the embedded web server. The U8/16-IP switch environment can be
entirely managed using a standard web browser. You can access the U8/16-IP using the
insecure HTTP protocol, or using the encrypted HTTPS protocol. Whenever possible, use
HTTPS.
The primary interface of the U8/16-IP is the HTTP interface. This is covered extensively in this
section. Other interfaces are addressed in the relevant subsections.
In order to use the Remote Console window of your managed host system, the browser must
feature Java Runtime Environment version 1.1 or higher support. If the browser has no Java
support (such as on a small handheld device), you can still maintain your remote host system
using the administration forms displayed by the browser itself.
For a non-secure connection to the U8/16-IP, we recommend the following browsers:
Microsoft Internet Explorer version 6.0 or higher
Netscape Navigator 7.0 or Mozilla 1.6
In order to access the remote host system using a securely encrypted connection, you need a
browser that supports the HTTPS protocol. Strong security is only assured by using a key
length of 128 Bit. Some older browsers do not have a strong 128 Bit encryption algorithm.
Important:
We recommend you install the latest version of Sun’s
Java Virtual Machine which can be downloaded from the
following web site:
www.java.com

5.5. Logging In
Login to the U8/16-IP
Launch your web browser. Direct it to the address of your U8/16-IP which you configured during
the installation process. The address used might be a plain IP address or a host and domain
name if you have given your U8/16-IP switch a symbolic name in the DNS.
Example: Type the following in the address line of your browser when establishing an
unsecured connection:
http://<IP address of U8/16-IP>
When using a secure connection, type in:
https://<IP address of U8/16-IP>
This will lead you to the U8/16-IP login page as shown below:
The U8/16-IP has a built-in super user account that has all the permissions enabled to
administrate your U8/16-IP switch:
Login name super (factory default)
Password
pass (factory default)
Please note: Your web browser has to accept cookies, or else login is not possible.
Please make sure you change the super user password immediately after you have installed
and accessed your U8/16-IP for the first time. Not changing the password for the super user is a
severe security risk and could result in unauthorized access to the switch and to the host
system(s) to which it is connected.
Note:
The user “super” is not allowed to login via the serial interface of the IP-KVM switch.
