RAD Data comm RIC-E1 operation manual Assigning a LAN IP Address to a New IR-IP

Appendix D IR-IP Interface Module RIC-E1Installation and Operation Manual

The IP address is actually retrieved from the ARP frames sent during pinging to locate the ping destination, not from the ping frames.

To ensure that the process is correctly performed, it is recommended to check the contents of the ARP table before starting the ping utility, to make sure that it does not contain the address to be assigned to the IP router LAN interface.

To view and edit the ARP table contents:

If the Telnet host you are using runs under Microsoft Inc. Windows™ 95, 98 or NT, use the following procedure to view and edit the ARP table contents:

1.Display the table using the arp -acommand.

2.If the table includes the intended IP address, remove it from the table using the arp -dcommand.

If for some reason the IP learning process does not succeed, before repeating it make sure to remove the IP address from the table.

Assigning a LAN IP Address to a New IR-IP

The following procedure enables you to configure the LAN IP address of a new IR-IP router, i.e., a router using the default parameters (see the Accessing the IR-IP Management Subsystem section above).

If RIC-E1 is already operating, skip Step 2 in the following procedure.

To configure the IP router LAN address:

1.Make sure the preparations described above have been completed, including the configuration of the ping utility.

2.Turn RIC-E1 on and monitor the IP router indicators:

The INT (LINK for RIC-E1/R) indicator turns on

The ERR indicator lights steadily for approx. 15 seconds, and then starts flashing at a rapid rate (about three times per second).

If the ERR indicator turns off, skip to the What to Do If ... section below.

3.Set section 1 of IR-IP DIP switch to ON or push the IP LEARN pushbutton on the RIC-E1/R panel.

The ERR indicator starts flashing faster (approximately four times a second).

4.Send a ping to the new address to be used by IR-IP. A confirmation should be received after the third ping: after the confirmation, the flashing will slow down to approximately twice a second.

If your host does not begin to receive ping replies after three unsuccessful attempts, skip to the What to Do If ... section below.

5.Return section 1 of the IR-IP DIP switch to the OFF position or push IP LEARN again to return the button to its initial position.

The ERR indicator must turn off.

At this stage, the communication with IR-IP router is lost, because its IP address has been changed. Therefore, you must reconfigure the destination IP address of the Telnet host. If you wish, you may also change the temporary IP address assigned to the host (192.168.205.2) back to its permanent address.
