For a description of how to configure these modules into your network,
see the CoreBuilder 3500 Getting Started Guide.
The modules contain one PWR (Power) LED, one INS (Board Inserted)
LED, and one ERR (Error) LED. Each port has one L (Link Status) LED, one
E (Error) LED, and one T (Traffic) LED. Each possible DAS connection has
one DAS LED between Port A and Port B, which indicates DAS status. This
