Warnings, cautions or notes related to the product WARNING! Risk of electric shock.Before turning RF power on, RF ports have to be terminated by nominal 50Ω load (for example, feeder with antenna). However, if these conditions are not met, the plastic caps that are delivered within the unused RF ports should remain in place. The plastic caps isolate RF power from the environment, and thus provide electric shock security in case RF power is accidentally on.
NOTICE: The RRH should always be mounted in a vertical orientation with connectors on the bottom side to ensure convection cooling.
Note: The minimum startup voltage is 40.5 V DC. If the input voltage is below/beyond extended limits, unit might shut down.
