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
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
