Chapter 3 Mounting and Alignment Overview

Aligning the Bridge Antenna Using RSSI LED Indications

You can align the integrated antenna using LEDs after the unit successfully associates with a remote
bridge. In the installation mode before association to another bridge, the Install LED blinks amber. If the
unit associates to a root bridge, the Install LED turns amber. If the unit does not associate to a root bridge
in the first 60 seconds, the Install LED blinks green to indicate that beacons are being transmitted and
that the unit is waiting for another non-root bridge to associate.
During the first 20 seconds after association, the unit reads the receive signal strength indictor (RSSI)
levels and records the maximum level received. After 20 seconds have elapsed, the Install LED turns
amber and the Ethernet, status, and radio LEDs display the relative RSSI levels compared to the
maximum received. The RSSI LED indications are shown in
Note For the signal level (dBm), a smaller number represents a stronger signal because the signal level is given
as a negative value.

1. Slow blinking rate of 1 blink/sec.
2. Medium blinking rate of 2 blinks/sec.
3. Fast blinking rate of 4 blinks/sec.
When using LEDs to maximize the signal, adjust the antenna until as many LEDs as possible are turned
on and the rest are blinking as fast as possible.
