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
