To select one of the network redundancy modes, do the following:
  1. Power down the adapter.
  2. Use the PRP/DLR rotary switch to select the redundancy mode.
    • The black x100 rotary switch positions on the left set the adapter to PRP mode.
    • The white x100 rotary switch positions on the right set the adapter to DLR mode.
  3. Power up the adapter.
Before you select one of the redundancy modes, verify your network settings to determine the redundancy mode used by your network.
IMPORTANT: The rotary switches only set the IP address when power is cycled.
IMPORTANT:
If you switch the adapter to a redundancy mode that is different from your network, the adapter disconnects from the network.
IMPORTANT:
You cannot switch the network redundancy mode while the adapter is running. A minor recoverable fault occurs to warn about the unintentional change to the network redundancy mode.
