4.2 Commissioning an Ethernet Product for Service
This section describes how to configure an Ethernet product so that it can be connected to
an existing network.
First, the network’s subnet must be determined.
Note: If a network administrator has provided you with an IP
address, subnet mask and default gateway, then this step can be
skipped.
This can be done using the
ipconfig
command in a Command Prompt on a Windows
xp computer that’s connected to the destination network as shown in Figure 27. To open
a Command Prompt, click Start | Run, and type
cmd
in the Open field.
Figure 27: The output of the
ipconfig
command.
To determine the network’s subnet, bitwise-AND the IP address with the subnet mask. In
the example of Figure 27, the IP address is 192.168.10.107 and the subnet mask is
255.255.255.0:
192.168.10.107 bitwise-ANDed with 255.255.255.0 yields 192.168.10.0—this is the
network’s subnet. It means that the Ethernet DataStick to be added must be given an IP
address between 192.168.10.1 and 192.168.10.254 in order to be accessible by other
devices on the network.
192.168.010.107
AND 255.255.255.000
192.168.010.000
