Input/Output Controller Description
The Input/Output controller shares the system memory functions and the environmental monitoring
functions with the network processing engine in the Cisco 7200 series routers and Cisco uBR7200
series routers.
The I/O controller consists of the following components:
• Dual EIA/TIA-232 channels for local console and auxiliary ports. The console port has full data
communications equipment (DCE) functionality and a DB-25 receptacle. The auxiliary port has
full data terminal equipment (DTE) functionality and a DB-25 plug.
• An optional Fast Ethernet port that is configurable for use at 100 megabits per second (Mbps)
full-duplex or half-duplex (half-duplex is the default). The Fast Ethernet port is equipped with
either a single MII receptacle (see Figure 1) or an MII receptacle and an RJ-45 receptacle (see
Figure 2). Although still supported by Cisco Systems, the I/O controller equipped with the single
MII receptacle was discontinued as an orderable product in May, 1998. The I/O controller
without the Fast Ethernet port is shown in Figure 3.
Note When using the I/O controller that is equipped with an MII receptacle and an RJ-45
receptacle, only one receptacle can be configured for use at a time.
You can install an I/O controller with or without a Fast Ethernet port in all Cisco 7200 series
routers (including the Cisco 7206 as a router shelf in a Cisco AS5800 Universal Access Server);
however, when you install an I/O controller with a Fast Ethernet port in a Cisco 7202, the system
software automatically disables the port.
If you order an I/O controller as a spare for a Cisco uBR7200 series router, use the product
numbers UBR7200-I/O= (without a Fast Ethernet port) or UBR7200-I/O-FE= (with a Fast
Ethernet port). These I/O controllers have the boot helper image used by a Cisco uBR7200 series
router loaded on the Flash memory SIMMs. The Cisco 7200 series I/O controller spares
(C7200-I/O-FE-MII=, C7200-I/O-FE=, and C7200-I/O=) do not have the Cisco uBR7200 series
boot helper image loaded on the Flash memory SIMMs.
