Before continuing, go ahead and verify power to both PWR1 and PWR2. Then temporarily
disable PWR1 and the LED for PWR1 will turn OFF. The FAULT LED should light. Note that
if the ping command can still get replies, then this exercise demonstrates that the redundant
power input function is working properly.
16. Exit Command Line Mode, and reconnect PWR1 power. At this point, your switch has been
tested and installation is complete.

(Optional - Example Network Application, Steps 17-23).
Refer to the following figure for
one example of how to setup a network using switches. Note that Computer A needs to
connect to several modems simultaneously to provide network access to many users.
However, Computer A does not have additional COM ports to connect all of the modems
available, and for this reason, we illustrate a network solution.
18. As shown in the figure above, we will use serial-to-Ethernet converters to network enable the
modems. These are available from several vendors. We also use standard Ethernet cables
to connect the switch to Computer A, and to connect to the serial converters. You can verify
network operation by entering Command Line mode on Computer A, and using the ping
command to verify each of the connections between Computer A and the converters, as
described in steps 10 and 11.
