Chapter 3 Mounting and Alignment Overview

Aligning the Antenna Using LED Indications

Use the Install LED to determine when the bridge successfully associates with a remote bridge and to verify its mode of operation. After association, the other three LEDs indicate signal strength (see Table 3-3).

The startup and association sequence depends on the bridge configuration, which can be one of the following types:

•Default—The bridge attempts to associate with a root bridge for 60 seconds. If it does not associate with a root bridge, it then attempts to associate with a non-root bridge.

•Preconfigured—The bridge attempts to associate with a remote bridge in the configured mode, either root or non-root. Because there are no timeouts, it is easier to align the antenna.

Aligning the Antenna Using LED Indications

You can align the integrated antenna using LEDs after the bridge successfully associates with a remote bridge. In the installation mode before association to another bridge, the Install LED blinks amber. If the bridge associates to a root bridge, the Install LED turns continuous amber. If the bridge does not associate to a root bridge in the first 60 seconds, the Install LED blinks green to indicate beacons are being transmitted and the bridge is waiting for another non-root bridge to associate. After association, the Install LED turns into continuous green and the Ethernet, status, and radio LEDs then display signal strength as shown in Table 3-3).

Note For the signal level (dBm), a smaller number represents a stronger signal because the signal level is given as a negative value.
