Step 7 - Confirm that the technician's computer can "ping" the customer's computer and/or
gateway on the same local sub-network.
Procedure:
From the technician's computer, open a DOS window and send a "ping" command to a
customer computer on the same local subnet. Ideally, you should "ping" the computer that
was used in the previous steps.
Question:
Was a response received to the "ping" command?
Yes - Proceed to step 8.
No - There is a network configuration error.
If the "ping" command returned the message "Request timed out", then there is a basic
network configuration error. Probably sub-net mask or gateway assigned for the AEC2.1 is
incorrect. Or the customer's gateway or router may not be configured properly.
If the "ping" command returned the message "Network unreachable", then the IP address or
netmask of the controller may be wrong.
If the computer uses a gateway, try to "ping" the gateway from the technician's computer.
If a response is received, then the customer's gateway or router may have a configuration
problem.
If no response is received, then the gateway address provided by the customer is incorrect, or
the gateway is not operating correctly.
Step 8 - Reconnect the AEC2.1 to the customer's network and test it by using the "ping"
command from the customer's computer.
Procedure:
1.
2.
Decision:
Did the customer receive a response to the "ping" command?
Yes - Proceed to step 9
No - One or more basic problems still exit. Repeat this procedure beginning with step 2.
Step 9 - Confirm that the AEC2.1 can be reached using a Web browser
Procedure:
2018.11 | 1.0.6 | F.01U.122.796
Disconnect the technician's computer from the network and reconnect the AEC2.1. Be
sure to use the same wall jack or hub port, and the same cable as used with the
computer.
Have the customer use one of his network connected computer's to send a "ping"
command to the address of the AEC2.1. The "ping" command should be performed from
a computer on the same local subnet as AEC2.1. Ideally, it should be the same computer
used in the previous two steps.
