Each DART Card provides an interface between the SeRF and the Power Amplifier they are 
spectrum specific. When additional service is needed another DART Card can be added to the 
HU and the corresponding cover added to a Remote Unit. Individual DART Cards may be 
replaced without disrupting service to the entire remote system. Only the RF spectrum of the 
DART Card being removed is affected. Refer to 

.

1. Before working on the HU or handling a DART Card, slip on an Electro-Static Discharge
