LEDs Chapter 3 Mounting Overview The Install LED provides bridge association status during installation mode as shown in Table 3-2. Table 3-2 Install LED Status Install LED Status Bridge State Off Self test Startup. Amber blinking Non-root, searching Not associated (non-root mode). The access point/bridge attempts to associate with a root bridge for 60 seconds1. Amber Non-root, associated Associated (non-root mode). Green blinking Root, searching Not associated (root mode). The access point/bridge attempts to associate with a non-root bridge indefinitely. Green Red Root, associated Error Associated (root mode). Overvoltage or overcurrent error2 1. Preconfigured bridges search indefinitely. 2. Disconnect power to the power injector, wait approximately 1 minute, and reconnect power. If error continues, contact technical support. 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.
