4-port FESMIC Header and Bus Locations
Note
The PC/104-
Plus
standard requires that the PCI bus and the ISA bus use keying features in the standard
stacking headers to guarantee proper module installation. On the PCI bus, pin D30 is removed and the
D30 opening is plugged. On the ISA bus, pin C19 and pin B10 are removed, and their openings are
plugged.
Signals for the FESMIC
The signals are delivered through 10-pin headers, with one set of Fast Ethernet signals per header. LED
signals and 5 V of power are provided through the 20-pin LED header. Cisco 3200 Series router cards
do not support any ISA bus signals.
The PCI bus connector supports communication between the FESMIC, the Serial Mobile Interface Card
(SMIC), and the Cisco 3270 Rugged Router card or Mobile Access Router Card (MARC). The Wireless
Mobile Interface Card (WMIC) communicates with the router through an internal Fast Ethernet port and
is configured through an independent console port; the WMIC draws power only from the bus.
The Fast Ethernet port signals are in compliance with IEEE 802.3. They are provided through the
Ethernet headers, which support the following:
•
Autonegotiation for 10/100BASE-TX connection
•
Full-duplex and half-duplex modes
•
Low-power sleep mode
•
10BASE-T and 100BASE-TX using a single Ethernet connection
•
Robust baseline-wander correction performance
•
Standard carrier signal multiple access collision detect (CSMA/CD) or full-duplex operation
•
Integrated LED drivers
