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.

IMPORTANT: After the display module is replaced in the 10K PDU, it still reports its model as a 10000 series device, APDU10Kxxxxx.

You can tell which 10K PDUs have replacement NMC3 displays by the firmware application version.

• 10K PDUs with original display modules have firmware version 2.x.x.x.
• 10K PDUs with NMC3 display modules have firmware version v3.x.x.x.

Note: The 11K PDU model number is APDU11Kxxxxx with firmware version v3.x.x.x.
