THIRD FCC DRAFT (CISCO CONFIDENTIAL)
When the bridge is initially powered-up, installation mode is activated and the bridge attempts to
associate to a root bridge for 60 seconds. If it is unable to associate with a root bridge, it automatically
assumes the root bridge role. The Install LED provides bridge association status during installation
mode as shown in Table 3.
Use the Install LED to determine when the br
idge successfully associates with a remote bridge and to
verify its mode of operation. After association, the other three LEDs indicate signal strength (see
Table 4).
The startup and association sequence depends on the bridge configuration, which can be one of the
following types:
Defa
ult—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.
Preco
nfigured—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 4).
