Discover PDU in DCE or ITE after replacing the display module with APDU9640NMC3

[JLehr]

After you replace the display module in a 10000 series PDU with the new APDU9640NMC3, it is recommended that you delete the PDU devices previously discovered in Data Center Expert or IT Expert and rediscover them. This will cause historical data loss.

Options to retain historical sensor data include:

• Download the data and save it before you delete the originally discovered PDUs and rediscover the updated PDUs.
• In DCE or ITE, put the originally discovered PDUs in maintenance mode, and then rediscover the updated PDUs under a new IP address.

  Note: This option uses twice the number of nodes.

• In DCE or ITE, rediscover the updated PDUs using the same IP address. Delete the sensors that are not important to you. The status of the remaining sensors from the previously discovered PDUs will be Unplugged.
• Backup your DCE server. Delete the originally discovered PDUs and add the updated PDUs as new devices. If the historical data is needed, the backup can be restored and the data can be accessed.
