Before you continue, make sure that both PWR1 and PWR2 are successfully connected to
power sources. When PWR1 fails, the LED for PWR1 will go out. At that moment, if the ping
command is still being replied to, then it proves that the redundant power input function works
normally.
16. Exit the Command Line mode, and connect PWR1 power input. At this stage, your JetNet
has been tested and the installation is complete.
17. See the figure below for setting up your industrial network with JetNets. Computer A needs
to connect several modems simultaneously in order to let a big number of users to access
this industrial network. However, Computer A does not have additional COM ports to
connect all of the modems. For this reason, we use a network solution.
18. We network enable the modems via serial-to-Ethernet converters, and use Ethernet cables
to connect Computer A and converters to the JetNet. Enter Command Line mode in
Computer A, and use ping command to see if the connections between Computer A and the
converters are working properly, as described in step 10 and 11.
19. Enter Telnet program in Computer A, type in the IP address of one of the converters, and
configure the serial port’s communication parameters. Follow this procedure to set up the
