About this task

To replace an NAE on a network site, update the site registration to ensure that devices on the site communicate with the new (replacement) engine; otherwise, devices may attempt to communicate with the network engine that was removed from the site.

If you do not remove the NAE from a site correctly, the Site Director may attempt to send messages to the old NAE , creating unnecessary network traffic.

If the NAE's trend data is stored in an ADS repository, forward the data prior to beginning the upgrade by following these steps for each engine:

  1. Select a supervisory engine in the Navigation tree.
  2. Select Action > Commands. A list of available commands appears.
  3. Select Archive, then click Send. The archived trend data is sent to the ADS/ADX.

To replace the NAE:

Procedure

  1. Using the SCT, upload the current copy of the NAE database.
  2. Physically replace the old NAE with the new NAE , connect the new NAE to the network, and power on the new NAE .
  3. Do one of the following:
    • Configure the NAE with the same host name and IP address of the old NAE from the Site Management Portal.
      Note: This configuration lets you download the database with SCT without using the Device Change option.
    • Verify that the SCT can communicate with the NAE , then select the Device Change option when downloading the database with SCT to identify the Site Director and host name of the new NAE .
  4. Download the existing NAE archive database to the new NAE.
