Cisco Connected Grid Modules for CGR 1000 Series—WiMAX Installation and Configuration Guide
OL-26236-03
Hardware Overview
Radio Frequency Interface
The Radio Frequency (RF) interface consists of two QMA connectors on the faceplate labeled MAIN and
AUX. Both antennas are mandatory; it both transmits and receives RF. The second AUX QMA connector
is for the optional RX Diversity.
DC Power Consumption
The average DC power consumption according to the duty cycle is as follows:
Temperature Monitoring State Machine
The state machine in the WiMAX module monitors the embedded module temperature. The command
show environment temperature shows the module temperature in Celsius. For example, the
temperature sensor of the WIMAX module shows as 46-degrees Celsius.
