Troubleshooting

• If the Ethernet indicator now turns on, this indicates a problem outside the monitor.
This could be a problem an external media converter (if used), or with the physical
connection on the plant network (possibly a damaged cable, bad Ethernet port on a
router or improper cable routing).
• Contact the plant IT personnel, and once they have fixed the connection to the plant
network, try Ethernet communications again.
• If the Link indicator does not turn on using a different network connection, contact Iris
Power LP Technical Support for assistance.

7.9.3. Ethernet Configuration
Once the physical Ethernet connection is verified, the Ethernet configuration needs to be
checked.
Using the IAM software, connect to the monitor over USB and check the IP address,
subnet mask and gateway address; verify that they are correct as provided by your plant IT
department.

• If the configuration was wrong, correct the error and try Ethernet communications
again.

Attempt to ping the IP address using a DOS prompt on a computer on the same network
(same gateway address and subnet mask) as the GuardII+.

• If the ping was successful, disconnect the GuardII+ Ethernet cable, and try the ping
again; this is expected to fail.

• If this second ping is also successful, then another device on the network is using the
same IP address as the monitor. Contact the plant IT department to resolve the
address conflict, and then try Ethernet communications again.
Connect to the GuardII+ Ethernet port directly using a laptop computer; note that the laptop
must have an Ethernet configuration that is compatible with the monitor. Attempt to use IAM
to communicate to the monitor over Ethernet from the laptop.

• If this connection succeeds, then the monitor Ethernet is working; this indicates that
there is a problem with the plant network.
