14.2 Ports
FDDI ports on mixed technology SwitchModules are Dual Attach Station (DAS) (A/B) ports that use MIC connectors.
14.3 Optical Bypass Connector
FDDI SwitchModules support one optical bypass connector per DAS port. Use the optical bypass connector to preserve a dual FDDI ring in the event of a station failure. The optical bypass connector accepts an optical bypass switch of type AMP
