Cisco 7206VXR Installation Guide - Page 33

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.
