Chapter 3 Mounting Overview
LEDs
The Install LED provides bridge association status during installation mode as shown in
Table 3-2
.
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.
The startup and association sequence depends on the access point/bridge configuration, which can be
one of the following types:
•
Default—The access point/bridge attempts to associate with a root bridge for 60 seconds. If it does
not associate with a root bridge, it attempts to associate with a non-root bridge.
•
Preconfigured bridge mode—The unit 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.
•
Preconfigured access point or workgroup bridge modes—the bridge Install LED does not operate.
Aligning the Autonomous Bridge Antenna Using RSSI LED Indications
For the autonomous bridge, 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
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.
