These switch types share the remarkable feature of being able to hold multiple SNMP network nodes in a single physical enclosure. They can contain up to four boards, each with its own SCP module and SNMP agent, which makes each board appear to the management system as a stand-alone ATM switch.
Of course, all boards populating an ASX-1x00 share certain hardware resources (the most important being ventilation and power supply units), but considering their independent networking and management functionality, the Fore Technolology Adapter handles each board as a logical ATM network node functionally equivalent to an ASX-200BX.
