When power is restored, the communication module reconnects with the network at a randomly
delayed time up to 30 minutes. This is to ensure that too many devices do not connect to the cell
tower simultaneously. With network communications restored, the communication module sends a
power restoration message that includes details such as:
delayed time up to 30 minutes. This is to ensure that too many devices do not connect to the cell

power restoration message that includes details such as:
•
LAN ID
•
Power Restoration Timestamp
•
Power Outage Timestamp
•
Sustained Outage Count
The communication module stores a history of power outage and restoration event pairs in the event
log. The user may request this data using Command Center.

Downloading Firmware
At times it may be necessary to perform firmware upgrades to enhance or enable functionality. The
communication module, meter, and ZigBee firmwares may all be upgraded remotely over the air
from Command Center. Command Center will allow the user to perform firmware updates to indi-
vidual devices. However, updates may also be group addressed, making it easier to upgrade several
devices at once. When the endpoint completely receives the new code, it will reboot. After powering
back up, the device will load the new firmware and normal operation will resume. The Firmware
download can be scheduled in Command Center or done immediately.

NOTE: Meters must have custom attributes programmed at the time of manufacture. The cellular
endpoints are unique in that the SIM card must be activated prior to deployment of the endpoints.

Auto-Registration
Once powered up, the modules will begin the auto-registration process. This will allow installers to
walk away and have the meters complete the process on their own. For more information on auto-
registration for cellular meters, please refer to“Auto-Registration” on page 26.
