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.
SERVICE TERMINAL TROUBLESHOOTING
If the card does not bring up a Service Terminal, check link light
DS9. DS9 should be illuminated within approximately 0.5
seconds of application 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.
SNMP TROUBLESHOOTING
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, verify that the community strings are set up correctly.
To do this, go into the Service Terminal and select number 3 for
SNMP Communications. Then, select number 2 for
Display/Modify
Communities. Verify that the IP Addresses listed are valid for
your network. Verify that you are typing in the correct
community name when trying to access SNMP. The community
name is case sensitive.
