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 4-23.)
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. (See the second illustration in Figure 1-15
and Figure 1-16.)
C7200-I/O-FE
1
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 1-15.)
C7200-I/O Has no Fast Ethernet port. (See Figure 1-16.)
C7200-I/O-FE-MII
2
1 Fast Ethernet port; equipped with a single MII
receptacle. (See Figure 1-17.)
1. The Product Number C7200-I/O-FE does not specify MII because both an MII and an RJ-45
receptacle are included.
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.
