Bridge Installation Mode LED Indications
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 5-1.
You 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 5-2).
Note For the signal level (dBm), a smaller number represents a stronger signal because the signal level is given
as a negative value.
