Emerson MONITORING OpenComms Manuel D’Utilisation

“Ping” is a tool used to test the network. At the command prompt, 

type, “ping <address of card>”. Ping will respond that it received a 

reply from the card if the card is functioning properly on the network.
If the card is not functioning properly or is not connecting to the net-

work, ping will respond that the request it sent to the card has timed 

out.
If the ping request times out, go to the Service Terminal to verify that 

the card initialized the network when it powered up. If the card is sit-

ting at the text “Initializing network…” then the card has not con-

nected to the network. Hit <enter> to go into the Service Terminal. 

Select No. 2 for the Network Interface Menu. Verify that you have the 

boot mode set up correctly. If you choose a static IP Address, verify 

that the IP Address is valid for your network.
If you obtain your network information from a BootP or DHCP server, 

verify that the server is valid and that it is responding to requests. 

Once the information has been verified, press <escape> to return to 

the main menu and select “x” to exit out of the card. Then, reboot the 

card. The card may be rebooted by pressing switch S1 on the card for 

approximately 2 seconds until the DS9 link light turns off.
If the card still does not connect to the network, or ping still does not 

receive a reply from the card, verify proper set up on the card itself. 

DS4 should be illuminated if the card detects the network. Verify that 

the network cable is connected to Ethernet port J3 and that the hub/

router/switch to which the card is connected is operating correctly.
Once this information is verified, reboot the card.

If the card does not bring up a Service Terminal, check link light DS9. 

DS9 should be illuminated within approximately 0.5 seconds of appli-

cation of power. If DS9 is not illuminated and no other LED's are on, 

verify that power has been applied to the card. If power has been 

applied, verify wiring connected to TB3 is correct. TB3 should have 

24VAC or 12 VDC applied. Reboot the card once the power to the card 

has been verified.

If SNMP is not functioning, first make sure that the card powers up, 

the Service Terminal is functioning and the card is connected to the 

network (verified by using ping). If all of those conditions are met, ver-

ify that the community strings are set up correctly. To do this, go into 

the Service Terminal and select number 3 for SNMP Communications.
