Environmental Conditions
The RRS-Hx Series Sensor is designed to operate at 100% transmit duty-cycle in
ambient temperature conditions of up to 50 C provided there is airflow across the back
plate of the device. The RRS can also operate at 100% transmit duty-cycle in ambient
temperature conditions of up to 35 C when mounted with the back-plate flush against a
horizontal surface.
The RRS-Sensor can operate at higher ambient temperature conditions by autonomously
controlling the transmit duty-cycle. However, once the internal microprocessor reaches a
temperature of 104 C, the RRS software will shut down to prevent damage and memory
corruption.

Power over Ethernet
Power over Ethernet (POE) is a mechanism for supplying power to network devices over
the same cabling used to carry network traffic. POE allows the RRS to receive both
power and data over a single cable. This feature simplifies network installation and
maintenance by using an Ethernet switch with integrated POE as a central power source
for all RRSs. The challenge during installation is to calculate the total power
consumption required making sure it is less than the power budget of the Ethernet switch.
The Juniper EX2200-24P-4G is a recommended switch for RRS networks due to its
remote manageability and sufficient 400W power budget to provide POE for an RRS on
each of the 24 ports. However, any 48V POE+ switch is sufficient.
