Erasing the Stored IP Address
Before removing any adapter from service, you should clear its IP address.
Writing a logical 0 (zero) will clear the adapter stored parameters and will reduce the possibility of a duplicate IP address appearing on your network if the adapter is later restored to service.
The adapter has a non-volatile RAM area for storing its assigned IP parameters. The parameters are retained when power is removed from the adapter, and will remain permanently in the adapter when it is removed from service. If the adapter is subsequently returned to service it would be possible for it to cause unspecified activity on your network. You should therefore erase the current parameters before removing the adapter from service.
The adapter has an internal register which defines the boolean state (saved or not saved) of its IP parameters. The register can be read by the application, and it can be written into causing the adapter to clear the parameters.
Removing Operating Power and Disconnecting the Adapter
Before removing the adapter, remove the operating power from the I/O base. Then disconnect the Ethernet cable, and remove the adapter from the base.
Installing the New Adapter
Mount the new adapter onto the I/O base, following the instructions supplied with the new adapter. Record the new adapter’s IEEE global address (MAC address), and use it to configure an Internet protocol address (IP address) for the adapter. Secure the ground screw.
