Alarm Table
Network Unit Hardware
Error
Network Unit Hardware Error - Power cycle the Network Unit (NU) and
check for software updates. If problem persists, return NU for service.
Insufficient Donor Signal
Insufficient Donor Signal - Relocate Network Unit (NU) where a stronger signal
exists, or use an external antenna for the NU. If using a small cell, verify the small
cell can process calls and check the connections to the NU. Power cycle the NU.
Coverage Unit Hardware
Error
Coverage Unit Hardware Error - Troubleshoot any Network Unit (NU) error first,
and check for software updates. Make sure Coverage Unit (CU) cables do not
exceed 100m (or 100m + QRE + 100m). Note that standard Ethernet Extenders or
active LAN switches and routers will not work with CU cabling. Power cycle the
CU by detaching and reattaching the LAN cable. Test CU by plugging it into back
of NU with short test cable.
Donor Signal Too Strong
Donor Signal Too Strong - Move Network Unit (NU), or re-aim NU external
antenna. Strong signal source may be from another Operator's device (cell tower,
local small cell, or booster).
