6. Ethernet Network Interface Setup
To perform initial setup of the network management interface on the A/B Switch you will need a serial terminal
capable of 9600 baud, no parity, 8 data bits, and 1 stop bit. Connect this terminal to the DB9 console connector on
the A/B Switch. A straight thru M/F cable is required to connect to an IBM PC standard DB9 serial port. For
connection to other device types a custom cable pinout may be required - see Table 6.1 below for the DB9 pin
assignment on the A/B Switch.
Apply power to the system.
After initialization is complete you will see a sign-on message displayed on the serial console, e.g.

At this point the A/B Switch is ready to accept the configuration commands that are necessary before you will be
able to communicate with the unit over an Ethernet network. You will need to enter an IP address, subnet mask, and
gateway address information for basic access. You will also need to set the read and write SNMP community names
if using SNMP, or a web password to allow web browser access, or a telnet password if you plan to control the A/B
Switch via telnet. After entering these parameters you will need to save them into non-volatile memory on the A/B
Switch. Any time one or more of these parameters is changed; they must be saved followed by a system RESET in
order for the changes to become permanent. The following shows a typical setup session. Change the entered
parameters to suit your application requirements. All of the console level commands are described in detail in
section 7.
>set ipaddress 192.168.1.200
OK
>set subnetmask 255.255.255.0
OK
>set gateway 192.168.1.1
OK
>set readcommunityname public
OK
>set writecommunityname private
OK
>save
OK
>reset
resetting, please wait . . .
After the system reinitializes, you will again be greeted by the sign-on message as before. At this time you can
connect an Ethernet cable to the 10Base-T network port on the A/B Switch and to an available port on your Ethernet
switch or router. The A/B Switch will respond to SNMP, telnet and HTTP messages at the assigned IP address.
