Wireless Modem Card and Subsystem Overview
Power Feed Panel
The power feed panel provides DC power, transmit and receive IF signals, frequency reference, and
control signals to the wireless transverters. The unit contains circuit breakers for the DC power, and
secondary lightning protection circuitry for the control cables. Local or national codes may require you
to install primary lightning protection for the IF cable and the control cable.
The power feed panel consists of the following components:
• Power LEDs on front and rear panel
• Connector ports
– Coaxial cable connection to the wireless modem card and the wireless transverter (main and
diversity)
– Control cable connection ports to the wireless modem card and wireless transverter (main and
diversity)
• Power ON/OFF breaker switches (main and diversity)
• DC power supply terminal block
• Ground lug
Main—Monitor SMA (female) Output For connection to spectrum analyzer
for test/troubleshooting purposes.
Note The monitor output level is the
same as that of the power feed
panel.
Main—PFP SMA (female) Output 24-MHz reference, receive and
transmit IF signals.
Debug Port For factory use only.

LED Function
Carrier LED Indicates the state of the radio link. When green, the radio link is synchronized and
the line protocol is up. When yellow, indicates loss of link synchronization.
Out of Service
LED
Indicates the service availability of the radio link. When yellow, the radio link is
still up, but not available for use (typically in a test or loopback mode).

When yellow, indicates the occurrence of a minor alarm in the radio subsystem. The
link is degraded and may need maintenance action or, one or more user-defined
event thresholds have been exceeded.
Major Alarm
LED
When yellow, indicates the occurrence of a major alarm in the radio subsystem. The
link is down.
Enabled LED When green, indicates that the wireless modem card is on, receiving power from the
router midplane, and enabled for operation. This LED remains on during normal
operation of the Cisco uBR7200 series router.
