Management Options
This system may be managed out-of-band through
the console port on the front/back panel or in-band
using Telnet. The user may also choose the web-based
management, accessible through a web browser. Each
Switch must be assigned its own IP Address, which is
used for communication with an SNMP network manager
or other TCP/IP application (for example BOOTP, TFTP).
The Switch's default IP address is 10.90.90.90. The user
can change the default Switch IP address to meet the
specification of your networking address scheme.
Web-based Management Interface
After a successful physical installation, you can configure
the Switch, monitor the LED panel, and display statistics
graphically using a web browser, such as Google Chrome
or Microsoft Internet Explorer.
The equipment you need to begin the web configuration
of your device:
• A PC with a RJ-45 Ethernet connection
• A standard Ethernet cable
Step 1
Connect the Ethernet cable to any of the ports in front
panel of the switch and to the Ethernet port on the PC.

cable
Step 2
To begin managing your Switch, open the browser you
have installed on your computer and enter the IP address
of your device in the format http://xxx.xxx.xxx.xxx where
the xxx is a number between 1-255. For the user who
wants to access the device for the very first time, enter the
factory default IP address 10.90.90.90, and press Enter.

Step 3
This opens the management module's user
authentication window, as seen below.

Leave both the User Name field and the Password field
blank and click OK. This will open the Web-based user
interface.
NOTE: The Switch's factory
default IP address is 10.90.90.90
with a subnet mask of 255.0.0.0
and a default gateway of 0.0.0.0.
Connecting the Console Port
The Switch provides an console port that enables a
connection to a computer or terminal for monitoring and
configuring the Switch. This port is implemented as a data
communication terminal equipment (DCE) connection.
To use the console port, you need the following equipment:
• A terminal or a computer with both a serial port and the
ability to emulate a terminal.
• A console cable to connect console port on the Switch.

cable
To connect a terminal to the console port:
1. Connect the console cable directly to the console port
on the Switch.
2. Connect the other end of the cable to a terminal or to
the serial connector of a computer running terminal
emulation software. Set the terminal emulation
software as follows:
