Chapter 1 Cisco 7200 VXR Product Overview
Field-Replaceable Units
Figure 1-18 C7200-I/O-FE—With MII and RJ-45 Fast Ethernet Receptacles (Version 2)
Note Your I/O controller with the MII and RJ-45 Fast Ethernet receptacles (C7200-I/O-FE) might look like
Figure 1-17, or it might look like Figure 1-18. There is no functional difference between these two
I/O controllers with the Fast Ethernet port.
Note In Figure 1-17, the NVRAM is replaced by an SRAM component (U14) that is made to act like the
NVRAM by the addition of some external components, one of which is the button-type lithium battery
labeled “Battery for SRAM.”
Note Your I/O controller without the Fast Ethernet port (C7200-I/O) might look like Figure 1-19, or it might
look like Figure 1-20. There is no functional difference between these two I/O controllers without the
Fast Ethernet port.
