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.
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
