Field-Replaceable Units

Input/Output Controller

This section describes five different models of I/O controllers. These models are distinguished from one

another by their Ethernet interface options. Table 1-22 lists the I/O controllers by product number and

describes their differences.

Note For a description of the configuration commands you need to configure the different interfaces on your

I/O controller, refer to the Input/Output Controller Replacement Instructions document.

You can also identify your I/O controller model from a terminal by using the show diag slot 0 command.

(See the “Viewing Your System Configuration” section on page 4-20.)

The I/O controllers consist of the following components and options:

• Ethernet, Fast Ethernet, or Gigabit Ethernet interface options

• Dual channels for local console and auxiliary ports

The console port has full data communications equipment (DCE) functionality and the auxiliary port

has full data terminal equipment (DTE) functionality.

• NVRAM for storing the system configuration and environmental monitoring logs

Note NVRAM uses lithium batteries to maintain its contents when disconnected from power.

Some I/O controllers use a static RAM (SRAM) component with an external lithium battery

to provide the same functionality as the NVRAM.

• Two PC Card (PCMCIA) slots that hold Flash Disks or PC cards for storing the default Cisco IOS

software image

• Flash memory for storing the boot helper 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 chassis

for 10/100-Mbps operation. (See Figure 1-16.)

C7200-I/O-FE

1. The Product Number C7200-I/O-FE does not specify MII because both an MII and an RJ-45 receptacle are included.

1 Fast Ethernet port; equipped with an MII receptacle and an RJ-45 receptacle

for use at 100 Mbps full-duplex or half-duplex operation. Only 1 receptacle

can be configured for use at a time. (See Figure 1-17.)

C7200-I/O Has no Fast Ethernet port. (See Figure 1-19.)

C7200-I/O-FE-MII

2. The I/O controller with the Product Number C7200-I/O-FE-MII has a single MII Fast Ethernet receptacle only. Although still

supported by Cisco Systems, this I/O controller with a single MII receptacle is no longer an orderable product as of May 1998.

1 Fast Ethernet port; equipped with a single MII receptacle. (See Figure 1-21.)
