LED status Description Alarm
RRH - red, stable A critical alarm has occurred or a reset is ongoing (red Critical alarm
stable for max. 5 s, then yellow stable).
RRH - red, blinking A major or minor alarm has occurred. Major or
minor alarm
RRH - yellow, stable Module is on and the status is set to ‘waiting’ or ‘blocked’. No alarm
RRH - yellow, blinking SW download is in progress or configuration is ongoing. No alarm
Module is non-operational at the moment.
RRH - green, stable Module is operational. No alarm
RRH - green, blinking Module is loading software or parameters. No alarm
RRH OPTx port - green, stable SFP link is connected to the System Module or extension No alarm
sub-module.
RRH OPTx port - red, stable SFP is installed, but no fiber or link is present. No alarm
RRH OPTx port - switched off No SFP or SFP power is down. No alarm
RRH TX - green, stable PA power is on. No alarm
RRH TX - green, blinking PA power is off. No alarm
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.
