card Id

1.3.6.1.4.1.50.1.2.1.2.3.1.2

The type of card installed in the concentrator. If the chassis is a modular chassis, then cardId defines the type of card. However, if the chassis is an 841 or 861 type chassis, then boxChassisId fully defines the type of card installed, so for a non-modular chassis the cardId specifies the Revision level.
