IX. Tips
Most installation issues involve these three categories. Mastering each one helps assure a
quick installation, and best performance.
• WAVE Portal connectivity
• CU cables
• Donor antenna selection, placement, and aiming
WAVE Portal Connectivity
This topic has already been covered at length in this guide. If using the wired LAN connection,
use the Connectivity Test function in the downloadable WAVE Field Tool to test your firewall
settings if needed.
If using the internal modem, make sure that a cellular signal antenna is plugged into the CELL
port atop the NU, and that this antenna connection is providing a usable cellular signal. Also
verify that a SIM card is properly inserted into the SIM card slot on the NU, and that the SIM
card has an active service plan. If the NU is online, you can check the modem state using the
SIM Card Status button on the Systems page. If using your own SIM, be sure to set up the
APN properly using the WAVE Field Tool.
Once a system is online, always update the software by selecting Software Update using the
Options menu on the Systems page. This will harmonize the software versions on all of your
EVO components and help ensure that you have the latest features and software
improvements.
See Nextivity Support materials in the Nextivity Partner Portal for helpful documents, videos,
and the Nextivity University training materials on how to use the portal to your advantage.
CU Cables
Alarms on the CU category cables are the most common alarm during an installation, and they
are easy to resolve. Trust the CU# LEDs on the NU and HUB. CU cables are constantly tested
by the system. If the LEDs indicate a problem, test the cables.
You can test a CU with short machine-made Ethernet cables by plugging the CU directly into
the NU. If the NU and CU function properly, then troubleshoot both cables to the CU.
Proper category cabling practices may be found in the CU installation sections of this guide.
Usually, merely re-crimping the cable RJ45 terminations, and re-inserting the RJ45 terminators
a few times to clean the contacts will resolve the problem. You can also select the CU Cable
Port graphic in the Radio Data page for your system, where you can view whether a cable is
in service (green) and see the cable length as measured by the system in meters. If a cable is
too long, a QUATRA Range Extender should be installed halfway along the CU cable length.
