Input/Output Controller
The I/O controller shares the system memory functions and the environmental monitoring functions for
the Cisco 7206 router with the network processing engine. It contains the following components:
• Flash memory for storing the boot helper image
• Two PC Card slots for Flash Disks or Flash memory cards, which contain the default Cisco IOS
software image
• Boot ROM for storing sufficient code for booting the Cisco IOS software
• Two environmental sensors for monitoring the cooling air as it enters and leaves the Cisco 7206
chassis
Note Detailed instructions for removing and replacing the I/O controller are contained in the Input/Output
Controller Replacement Instructions document. This document is available on Cisco.com.
The I/O controller is available in these versions: C7200-I/O-FE-MII, C7200-I/O-FE=.
• The C7200-I/O-FE-MII and C7200-I/O-FE= I/O controllers consists of the following components:
–
Dual EIA/TIA-232 channels for local console and auxiliary ports. The console port has full
DCE functionality and a DB-25 port. The auxiliary port has full 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 an MII port and an RJ-45 port (C7200-I/O-FE=) (see Figure 1-9), or a single MII port
(C7200-I/O-FE-MII=) (see Figure 1-11). Although still supported by Cisco Systems, the I/O
controller equipped with the single MII port (C7200-I/O-FE-MII=) is no longer an orderable
product as of May 1998. The I/O controller without the Fast Ethernet port (C7200-I/O=) is
shown in Figure 1-10.
Note The I/O controller with the Product Number C7200-I/O-FE-MII= has a single MII
Fast Ethernet port only. The Product Number for the I/O controller with two Fast Ethernet
ports, C7200-I/O-FE=, does not specify MII because both an MII and an RJ-45 port are
included.
