Ethernet link detected, connection is in progress.
Wait up to 2 minutes. If LED status continues, determine the number of
Signal Strength LEDs:
None
n Power off the Digi EX15, swap the antennas on the back of the
Digi EX15, and power on the Digi EX15. If this resolves the
connectivity and there are two or more bars of signal strength,
this may indicate that one of the antennas is faulty. You can
continue to use the Digi EX15, but we suggest that you
eventually order a replacement set of antennas to improve
signal strength even further.
n If swapping the antennas did not resolve the issue, verify the
SIM card is inserted properly. Power cycle the Digi EX15 after re-
insterting the SIM card. Wait 30 to 60 seconds. If the problem
persists, the unit cannot detect the SIM and the Digi EX15 may
need to be replaced.
One
Relocate the Digi EX15 to an area with better signal reception.
Two or more
Verify that the embedded cellular modem firmware matches the carrier
type.
Check the SIM card and the Modem section of the config to verify both
are set up with the proper APN.
Login to the web UI. Open the Status page and click on the Cellular
Details Tab. Are the Provider and ICCID values listed?
No
n If the proper Carrier is not listed, contact the cellular provider to
verify SIM card activation.
n Try pressing the Erase button (no longer than half a second) to
restore default settings. If the SIM card requires a custom APN
to connect, you will have to manually reconfigure that on the
Digi EX15
n If resetting the configuration did not resolve the issue, check if
the SIM card is provisioned properly. If it is, then there may not
be coverage for the desired network in your area.
n Try moving the Digi EX15 to a different location or try using a
different cellular provider's SIM card.
