In an Ethernet Daisy Chain, will downstream meters still communicate if a meter loses power?

Product Line:
PM8000, PM5500

Environment:
PowerLogic meters with multiple Ethernet ports

Cause:
Unlike a serial daisy chain, if a meter in an Ethernet Daisy Chain loses power, all devices downstream of the device will lose communciations. This is due to the meter also containing a network switch which needs to remain powered in order for traffic to pass through. 

Resolution:
To ensure that there are no comms loss due to power outage on Ethernet devices, a UPS can be installed to ensure that the meter does not power off during a service interrupt.
