Note Your I/O controller with the MII and RJ-45 Fast Ethernet receptacles
(C7200-I/O-FE) might look like the first illustration in Figure 1-15,
or it might look like the second illustration in Figure 1-15. There is
no functional difference between these two I/O controllers with the
Fast Ethernet port.
Note In the second illustration in Figure 1-15, 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 the first illustration in Figure 1-16, or it might look
like the second illustration in Figure 1-16. There is no functional
difference between these two I/O controllers without the
Fast Ethernet port.
Note In the second illustration in Figure 1-16, 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
