Fast Ethernet Switch Mobile Interface Card
(FESMIC)
The Fast Ethernet Switch Mobile Interface Card (FESMIC) is a mobile interface card (MIC) in a
standard PC/104-Plus form factor. FESMICs are components of the Cisco 3200 Series Mobile Access
Router. The 4-port FESMIC provides 4 sets of switched 10/100 Fast Ethernet signals. The
2-port FESMIC provides 2 sets of switched 10/100 Fast Ethernet signals.
The key features of the FESMIC include the following:
• Auto-sensing switched 10/100 Fast Ethernet interfaces.
• Auto-MDIX (medium-dependent interface crossover). Auto-MDIX automatically detects and
corrects crossed Ethernet cabling.
• Support for 802.1D standard bridging, 802.1Q trunking, and 802.1P class of service (CoS).
• Layer 3 routing support between VLANs.
Additional cards and components provide power and link interfaces to the FESMIC. The exact
configuration of your router will vary, depending on how it was configured by your vendor.
Note This section provides basic information about the FESMIC hardware for the purpose of performing
simple troubleshooting, such as reconnecting a loose cable. To solve more difficult problems, please
contact your vendor.
The FESMIC draws power from the PCI and the ISA connectors. Table 2-1 shows the estimated power
consumption. Note that these are theoretical maximum wattages.
