The NCT captures SNMP broadcasts for any supported network engine, regardless of the disk image loaded on the engine.

Important: This method of finding an IP address requires you to disconnect power from the network engine, wait until all LEDs are off, and then reapply power. Network engine shutdown may adversely affect the current conditions of your Metasys system and the controlled equipment. Please verify with your customer that network engine shutdown is acceptable prior to shutting down the network engine.
Note: A message appears in the Recently Started Devices list if a network engine is assigned a new IP address after it sends the initial startup serial port message. The delay in IP address assignment occurs when a network engine is configured for DHCP, and the DHCP server is not responding or is responding slowly. If you attempt to use a serial port monitor to find the IP address of the network engine at this time, the monitor reads 0.0.0.0. As soon as the network engine is assigned an IP address, a message appears in the Recently Started Devices list with the correct address listed, and Step 2 and Step 3 below are not required.

To determine the IP address of a network engine using the NCT to capture the SNMP broadcast:

  1. Start the NCT on a computer connected to the building network.

  2. Disconnect power from the network engine and wait for all network engine LEDs to go off.

  3. Reconnect power to the network engine.

    In approximately 1 to 2 minutes for NCE25, NAE35, or NAE45 engines, or 2 or 6 minutes for NxE55 engines, the Recently Started Devices list shows information from the network engine you started. This list includes the date and time started, the network engine name, the IP address, the OS version, and the MAC address.

    Note: If no messages appear in the Recently Started Devices pane, the local network may be blocking broadcast messages. In this case, connect your NCT computer on the same side of the router as the network engine and perform this procedure again.
  4. When the network engine is in the RUN mode (RUN LED on), the SNMP broadcasts are captured for any supported network engine (including network engines without compatible disk images.)

    Note: For NCE25, NAE35, and NAE45 engines prior to Release 3.0, and for NxE55xx-1 engines without a compatible disk image, the IP address is broadcast via SNMP when the RUN light is on steady during startup.
