Global Cache iTach IR Test Device Installation
  • The iTach uses DHCP by default, however, DHCP is not the recommended setup for test automation
  • We will reconfigure the iTach to use a static IP address on the local test equipment network
  • We just have to get the right IP address setup on the iTach

To set a static IP address on an iTach:

  1. The iTach’s MAC address is listed on a small label on the bottom of the device
  2. Find any network that has a DHCP server, and connect the iTach
    • At this point, it doesn’t have to be the test network, we just want the iTach to be assigned an IP address
  3. Allow the iTach to be assigned an IP Address
  4. Figure out which IP address was assigned, this could be done in a number of ways:
    1. Log on to the DHCP server and find the iTach's MAC address in the reserved pool
    2. Use WireShark on a PC sharing an Ethernet Hub with the iTach
      • Observe the 4 packet DHCP exchange when the iTach boots up and note the IP Offering
    3. Use ‘arp –a’ at a command prompt then match the iTach’s MAC address to the IP Address
      • For example (iTach MAC of 00-0c-1e-02-28-4b has ARP entry on 10.10.1.41):

Set the static IP address, by using a web browser

  • Enter the iTach’s IP address in the address bar, like this:
iTach1.png
  • Then, select the ‘Network’ link on the left to access the iTach’s IP Setup page. Like this:
iTach2.png
  • Enter your desired IP address, then click ‘Save’
  • Power cycle the iTach
  • You may need to move the Ethernet cable so that it is plugged into the local test network
  • Verify the IP address by attempting to ping it from a command prompt
  • Verify that you can reach the iTach’s web server, by entering the new IP address in the browser’s address bar
  • Verify that Telnet works by telneting to the device on port 4998 (telnet 10.10.1.41 4998)
  • You now have the iTach configured
