C H A P T E R 6 Wireless Mobile Interface Cards (WMICs) The Cisco Wireless Mobile Interface Card (WMIC) is a Cisco 3200 Series router interface card in a standard PC/104-Plus form factor. It is one component of the Cisco 3200 Series routers and provides a wireless interface:
2.4 GHz (802.11b/g) Cisco 3201 4.9 GHz (public safety) Cisco 3202 5.0 GHz (802.11h) Cisco 3205 (The C3205WMIC-K9 and C3205WMIC-TP-K9 WMICs are available only in the European Telecommunications Standards Institute [ETSI] domain.) Caution The 4.9 GHz (public safety) radio requires an operators license and can only be operated by US Public Safety operators who meet the requirements specified under FCC Part 90.20. This chapter provides basic information about the WMIC hardware for the purpose of performing simple troubleshooting, such as reconnecting a loose cable. To solve more difficult problems, please contact your vendor. WMIC Component Systems The ISA buses and PCI buses on the Cisco 3200 Series router cards provide power to the components on the cards. The WMIC does not receive or transmit communications signals on either bus, but it will pass signals through the bus to a card above or below the WMIC. Both buses comply with the PC/104-Plus standard. The PCI bus signals allow the Cisco cards to communicate. Non-Cisco cards cannot communicate with the Cisco 3200 Series Router cards over the PCI bus. Caution If you add non-Cisco cards that generates signals on the PCI bus, the router might shut down. Please do not add non-Cisco cards that generate signals on the PCI bus. OL-5816-09 Cisco 3200 Series Router Hardware Reference 6-1 Chapter 6 Wireless Mobile Interface Cards (WMICs) Figure 6-1 shows the WMIC header and bus locations. Figure6-1 WMIC Header and Bus Locations 1 6 3 2 5 4 1 8 9 3 0 1 1 3 5 PCI bus Right antenna connector (J1) 10-pin Fast Ethernet header 2 4 6 Left antenna connector (J2) ISA bus 24-pin multifunction header Note The PC/104-Plus standard requires that the PCI bus and the ISA bus utilize 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 the C19 and B10 openings are plugged. Antenna Connector On the radio card, there are two ultra-miniature coaxial connectors (U.FL connector) that are used to connect the coax cables between the WMIC and the external antenna connectors. Two connectors are used to support antenna diversity. The cable should be as short as possible to minimize the loss in strength of the radio frequency (RF) signal. The cable carries the RF signal from the antenna to the low noise amplifier (LNA) on the receiver and transmits the RF signal from power amplifier (PA) to the antenna that radiates the RF signal. There are many antenna connector families. The Cisco RP-TNC antenna connector can be used to support standard antennas. WMIC Console and Fast Ethernet Ports Cisco 3200 Series router cards do not support any ISA bus signals. The PCI bus connector supports communication between Cisco 3200 Series router card and the Fast Ethernet Switch Mobile Interface Card (FESMIC) and Serial Mobile Interface Card (SMIC). In a Cisco rugged enclosure, the WMIC communicates with the router through the WMIC Fast Ethernet interface. The WMIC Fast Ethernet ports are connected internally to Fast Ethernet ports that provide a communications link with the router. Cisco 3200 Series Router Hardware Reference 6-2 OL-5816-09 Chapter 6 Wireless Mobile Interface Cards (WMICs) The WMIC interfaces are configured through a WMIC console port. In contrast, the Serial Mobile Interface Card (SMIC) and FESMIC communicate with the router through the PC/104-Plus bus. The interfaces are configured through the router console port, and all of the router and FESMIC Fast Ethernet ports are identified by using the slot/port format. The WMIC runs an independent IOS image and when it is configured, the link between the WMIC and the router forms an internal LAN. In standard configurations, a WMIC Fast Ethernet port is never brought out to the end cap. The WMIC console port is brought out to the corresponding RJ-45 port on the I/O end cap, replacing a Fast Ethernet port. If the router includes one WMIC, the RS-232 WMIC console port replaces a Fast Ethernet port on the end cap. If the router includes two WMICs, two WMIC RS-232 console ports replace two Fast Ethernet ports on the end cap. Note Currently, even if the router contains zero WMICs, in standard configurations a maximum of three Fast Ethernet ports are brought out to the end cap. Unused RS-232 ports are sealed. Fast Ethernet Signals on the WMIC The Fast Ethernet signals are delivered through a 10-pin header. LED signals and RS-232 console signals are provided through the 24-pin multifunction header. There is one set of fixed Fast Ethernet signals on the WMIC. The Fast Ethernet port signals are in compliance with IEEE 802.3. They are provided through the Ethernet headers, which support the following:
Auto-negotiation 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 Note If Auto-MDIX is disabled, when connecting to Ethernet switches or repeaters a straight-through cable can be used. When connecting to compatible workstations, servers, and routers, a crossover cable should be used. If Auto-MDIX is enabled, either a straight-through or crossover cable can be used can be used to make the connection, as the router automatically changes the signals on the pins to compensate. OL-5816-09 Cisco 3200 Series Router Hardware Reference 6-3 Chapter 6 Wireless Mobile Interface Cards (WMICs) LED Behavior During normal operations, the indicator signals on the wireless device have the following meanings. The status indicator signals operational status. Steady green indicates that the wireless device is associated with at least one wireless client. Blinking green indicates that the wireless device is operating normally but is not associated with any wireless devices. The radio indicator blinks green to indicate radio traffic activity. The light is normally off, but it blinks whenever a packet is received or transmitted over the radio. The Ethernet indicator signals traffic on the wired LAN. This indicator is normally green when an Ethernet cable is connected, and blinks green when a packet is received or transmitted over the Ethernet infrastructure. The indicator is off when the Ethernet cable is not connected. Table 6-1 shows the details of LED behavior.

A universal workgroup bridge can not associate with the Cisco WLAN AP with CKIP or CMIC encryption configuration. If the universal workgroup bridge is associated with a Cisco AP or third party AP and if the user issues the command show dot11 association all, the IP address and name information is not available. Users should configure the static IP address on the BVI when it is in the universal workgroup bridge mode, so that the WMIC is manageable from the MAR through the Mobile IP tunnel from the infrastructure side. If the dynamic CCoA is used on the Cisco 3200 Series Wireless and Mobile Router, you should configure the static IP address using the ip secondary address command. The universal workgroup bridge is not compatible with the Tropos version 3.1.1.2 AP. A universal workgroup bridge can not associate with the Cisco 1500 router when it is configured with the Allow WPA2 TKIP Clients option.
