11 7 Checking the LED Indicat ors The bridge’ s 11a and 11b/g LEDs operate in two di splay modes, which ar e configurable through the software. The default AP mode indicates data tra ffic rates. The RSSI mode indicates the received signal power and is for use when aligning antennas in a bridge link. When the bridge is connected to power , LEDs in[...]

12 8 Aligning Antenn as After wireless bridge units have been mounted, conn ected, and their radios are operating, bridge link antennas must be accurately aligned to ensure optimum perform ance. Th is alignment process is particularly important for long-range point-to-point links. In a point-to-m ultipoint configuration the root bridge uses an om n[...]

13 1 Pan the antenna horizontally back and forth while chec king the LED s. If using the pole- mounting bracke t with the unit, you m ust rotate the mounting brac ket around the pole. Other exter nal antenn a brackets may require a dif ferent horizontal adjustme nt. 2 Find the point wh ere the signal is strongest (all LED s on) and se cure the hori[...]
