CHAPTER 6. TROUBLESHOOTING
LED
ISSUE
TRY
SOLID RED
Network Unit
(NU) error.
Reset the Network Unit by unplugging the power supply, wait 5 seconds, then plug it
back in.
Verify Network Unit software is up to date (using QMT or cloud portal).
If the problem persists, return Network Unit for service.
Network Unit
overheating.
Make sure that the vents (the small openings in the plastic housing) on the units are not
blocked. Move the unit to a cooler area. The system will start working normally when it
cools down.
Coverage Unit
(CU) error.
Reset the Coverage Unit by unplugging it and then plugging it back in.
Verify Coverage Unit software is up to date (using QMT or cloud portal).
Make sure that the LAN cabling to each Coverage Unit is dedicated (not combined with
other active LAN hardware such as routers and switches). Passive connectors may be
used (i.e. punch-down blocks) but the maximum cable distance may be reduced.
If a Cel-Fi QUATRA Range Extender is used to lengthen the 100 meter maximum
Network Unit to Coverage Unit Ethernet distance, make sure only a single Cel-Fi QUATRA
Range Extender (QRE) is used per Coverage Unit. QRE is proprietary and other extenders
will not work. See QRE Troubleshooting.
Uninstall Coverage Unit and plug it into back of Network Unit with a short Ethernet cable
that is known to work. If the Coverage Unit works properly, troubleshoot the original
Ethernet cable (or QRE if used).
If the problem persists, return Coverage Unit for service.
Coverage Unit
overheating.
Make sure that the vents (the small openings in the plastic housing) on the units are not
blocked. Move the unit to a cooler area. The system will start working normally when it
cools down.
BLINKING
RED
Problem with
donor signal or
Mode setting.
Insufficient Donor Signal. If internal antennas used for Network Unit, relocate Network
Unit where signals exist or add and Enable external antennas in Settings.
If external antennas or a small cell donor signal are used, check Mode setting, donor
source, and cable connections to the NU RF ports.
Registration
required.
Product Registration is required for your system to operate (system is new or has been
moved to a new address). Please follow the registration instructions using QMT or the
Cel-Fi WAVE portal.
Check Mode and
number of CUs.
If NU Mode is set to Internal Antenna, only one CU may be used. More connected CUs
will result in system Disable. Disconnect additional CUs, or set NU Mode to External
Antenna and connect an External Antenna.
No CU
connected.
Connect at least one CU to the NU.
CU too close to
NU.
A CU is too close to the NU. Move the closest CU further away from the NU.
CU Disabled.
Use QMT or the Cel-Fi WAVE portal to Enable the CU if it is Disabled.
Input signal
too strong.
The Network Unit is receiving too strong a donor signal and may operate with reduced
gain (the signal source could be any Operator’s cell tower if close enough, or it could be
another indoor cellular solution in close proximity to the Network Unit donor antennas).
If internal antennas used, move the Network Unit to another location. You might need to
move your system to the other side of your building.
If external antennas used, move or re-aim the external antennas away from the strong
cellular signal source.
