2/ Why is the communication not working?
If the computer equipped with the gGuard software is not able to communicate with the
GFH, on the main screen of gGuard, you may see red under the Hood Status. If this is
the case there is usually one of four reasons why you cannot communicate.
1. You could be having network problems. Ask the IT staff on-site as there could be
an outage, upgrade or repair taking place on the network. Please ask your IT
representative.
2. The GFH lost its IP address information that was previously entered in the control
module. A network device may have caused the GFH to not retain its IP
information. At which case you must follow the Check GFH IP information.
3. The FTP server is locked. Your GFH control module acts as a FTP server and
your PC with gGuard acts as a client. If some network device prematurely closed
the FTP connection before the gGuard software was finished with the session the
FTP server can become locked. Follow the FTP server is locked procedure.
4. The network cable became compromised or unplugged from the control unit.
Especially if there was any maintenance, or service work done on or around the
GFH recently. Please check and reseat all connections.
To assist in determining which one is the problem, try these few things first from your PC.
At the command prompt try and ping the GFH in question that is not communicating on
the “home page.” StartRunCMDnow type ping <space> then the IP address of the
hood that is not communicating.
You will see 4 packets sent and 4 packets received if it can communicate. You will see 4
packets sent and 0 received if it cannot communicate.
Based on your results you have one of the following problems. If you can receive the
packets from the ping command then the FTP server is locked. It needs to be rebooted to
unlock the server and restart communication. Follow the FTP server is locked procedure.
If it cannot receive any packets then you must check the GFH network parameters, the IP
address, Subnet Mask, and Gateway. In which case you need to go to the hood with an
“administrator” card and follow check the GFH IP information procedure.
