Chapter 1 Product Overview
Field-Replaceable Units
Note
When you use the I/O controller that is equipped with an MII port and an RJ-45 port
(C7200-I/O-FE=), only one port can be configured for use at a time.
You can install an I/O controller with or without a Fast Ethernet port in all Cisco 7200 series
routers (including the Cisco 7206 and Cisco 7206VXR as router shelves in a Cisco AS5800
Universal Access Server).
–
Nonvolatile random-access memory (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 an SRAM component with an external lithium battery to provide the same functionality
as the NVRAM. (See the second illustration in
Figure 1-9
and
Figure 1-10
.)
Note
Your I/O controller with the Fast Ethernet port that has MII and RJ-45 ports (C7200-I/O-FE=) might look
like the first illustration in
Figure 1-9
, or it might look like the second illustration in
Figure 1-9
. There
is no functional difference between these two I/O controllers with the Fast Ethernet port.
