On the top panel of the RU are a set of 7 LEDs.

The second shows yellow if the RU is powered on.
•
The next 5 LEDs are green and show the LTE Signal Strength.
Ports
The RU has the following port configuration:
•
Two 10/100BASE-T Ethernet ports (RJ-45 connectors)
•
One RS-232 (DB-9) port with configurable GPIO
•
One mini-USB 2.0

Antenna Connectors
The RU has 4 SMA antenna connecters, two for the LTE WAN and two for the WiFi LAN. Any included antenna
can attach to any SMA connector on the RU. You MUST attach an antenna to the primary antenna port, labelled
PRI on the top of the RU. The diversity antenna, labelled DIV, can be excluded, but it will give you better overall
LTE performance in environments with weaker coverage. If the RU shows 5 bars with just the PRI antenna
connected, then you can confidently choose to not use the DIV antenna.
