Check the GFH IP information
With your Administration Card, in the “hood status” menu of the GFH concerned by this
problem, check the IP Address, GW, and Subnet Mask to make sure it equals what you
have in gGuard xxx.xxx.xxx.xxx and what is on your lab diagram.
If 0’s or not correct you must re-enter the IP information from your lab diagram to that
specific hoods network parameters.
To do this go to the “Administration Menu” press “OK” to select it.
Then arrow down to “Network Parameters” press “OK” to select it.
On “Ethernet” press “OK” to select it.
Tip here select DHCP “Yes” then “No” to get the subnet mask to partially fill out
if you have a static IP address.
Use the arrow keys to enter the IP information from your lab diagram. Once you
are sure it is correct press “OK” to “save and exit.”
Now go back to the PC with gGuard and “double click” on the hood in question. Once the
window opens to that hood press “F8” to force an immediate download of the file from the
hood.
FTP Server is locked
If the IP information is correct but you still cannot communicate with the hood you must
reboot the controller to unlock the FTP server.
To do this:
1. Press the light and fan icon on the controller and wait 30 seconds for it to turn off.
2. On the left side of the controller with the problem, pull out the black fuse cartridge
just enough to see the first fuse and break the power connection.
3. Wait 30 seconds and then push it back in. You will see it say “Booting” then
come up. Then turn the fans on with the “user” card.
4. After it is on, go to the computer with gGuard and “double click” on the hood in
question. Once that window opens press “F8” to force an immediate download of
the file from the hood.
