I/O End Caps for the Cisco 3200 Rugged Enclosures

The I/O end cap has multiple connectors for connecting power and data cables. The end cap

configurations shown in this section are fully populated; however, the number of ports and their

functions may differ, depending upon the number of WMICs in the system.

Internally, five Fast Ethernet ports are available: one routed Fast Ethernet port on the router card and four

switched Fast Ethernet ports on the Fast Ethernet Switch Mobile Interface Card (FESMIC). When a

WMIC is installed in addition to the router, the WMIC Fast Ethernet port is connected internally to the

routed Fast Ethernet port on the router card or is connected to one of the switched Fast Ethernet ports on

the FESMIC to provide a communications link with the router. In contrast, the Serial Mobile Interface

Card (SMIC) and FESMIC communicate with the router through the bus. All the router Fast Ethernet

ports are addressed by using the slot/port format.

In typical configurations, the first WMIC Fast Ethernet port is connected to the routed Fast Ethernet port

on the router card. The Fast Ethernet ports of the second and third WMICs are connected to FESMIC

switched Fast Ethernet ports. The differences in the types of the router Fast Ethernet ports that the

WMICs are connected to affect how they are configured, as, for example, when uploading a Cisco IOS

image to a WMIC.

The WMIC runs an independent Cisco IOS image and when you configure the WMIC, the link forms an

internal LAN. In standard configurations, the 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 EIA/TIA-232 WMIC console port replaces a

Fast Ethernet port on the end cap. If the router includes two WMICs, two WMIC EIA/TIA-232 console

ports replace two Fast Ethernet ports on the end cap.

Note At present, even if the router contains no WMICs, in standard configurations the maximum three Fast

Ethernet ports are brought out to the end cap. Unused EIA/TIA-232 ports are sealed.
