Cisco C3251MARC-TP-RF

The Cisco 3251 Mobile Access Router Card is one component of the Cisco 3200 Series Mobile Access Router. It includes the host processor, memory, and headers for the 10/100 Fast Ethernet, console, and auxiliary signals for the router.The industry-standard architecture (ISA) buses and peripheral component interconnect (PCI) buses on the Cisco 3200 Series Mobile Access Router cards provide power to the components on the cards. Both buses comply with the PC/104-Plus standard. The ISA bus allows PC/104-Plus ISA signals to pass through the card bus, but the Cisco cards do not use any of the signals.The PCI bus signals allow the Cisco cards to communicate. Non-Cisco cards cannot communicate with the Cisco 3200 Series Mobile Access Router cards over the PCI bus.There is one fixed 10/100 Fast Ethernet port on the Cisco 3251. A Cisco router identifies a 10/100 Fast Ethernet interface address by its slot number and port number, in the format slot/port. The slot/port address of a Fast Ethernet interface on the Cisco 3251 is 0/0.
