1.  Connect one end of the power cord that came with the ITG to the power receptacle on 

the rear panel. 

2.  Connect the other end of the power cord to an AC power outlet. 

3.  The ITG will execute the memory testing and application code automatically.. 

2.6  Assigning IP address to the ITG 

The IP address is the unique logical address identifying each IP node, such as the ITG, on an 
IP network. An IP address is a 32-bit number expressed as four decimal numbers from 0 to 
255 separated by periods. The ITG needs a static IP address and be aware of the subnet mask 
and default gateway (typically a router) of your network to be able to send to and receive 
data from the IP network. Consult your network manager to obtain a unique and static IP 
address for the ITG, the IP subnet mask and default gateway of your network, and fill out the 
work sheet in Appendix D before configuring the gateway. Procedures for assigning IP 
address, default gateway and subnet mask is available in Chapter 4.
