Aligning The Antenna Using Led Indications - Cisco Aironet 1400 Series Hardware Installation Manual

Chapter 3 Mounting and Alignment Overview
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
The startup and association sequence depends on the bridge configuration, which can be one of the
following types:

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

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.
