IP Address Record the bridge MAC address in a safe place before the bridge is installed in a hard-to-reach location. The MAC address is printed on the back of the bridge. Additional IP address labels are shipped with the bridge. Location The WL-575 bridge must only be installed outdoors. - Page 5 Fit the edges of the V-shaped part into the slots in the rectangular plate, and tighten the nuts. Slots Attach the adjustable rectangular plate to the bridge with the supplied screws.

Page 6: Using The Wall-Mounting Bracket
Attach the bridge with bracket to the plate already fixed to the pole. Use the included nuts to secure the wireless bridge to the pole bracket. Note that the wireless bridge tilt angle may need to be adjusted during the antenna alignment process. Be sure to take account of the antenna polarization direction;... -
Page 7: Connecting External Antennas
Position the bracket in the intended location and mark the position of the four mounting screw holes. Drill four holes in the wall that match the screws and wall plugs included in the bracket kit, then secure the bracket to the wall. Use the included nuts to tightly secure the wireless bridge to the bracket. -

Page 11: Checking The Led Indicators
Checking the LED Indicators The bridge’s 11a and 11b/g LEDs operate in two display modes, which are configurable through the software. The default AP mode indicates data traffic 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 indicate as follows: Color Indicates... -
Page 12: Aligning Antennas
Aligning Antennas After wireless bridge units have been mounted, connected, and their radios are operating, bridge link antennas must be accurately aligned to ensure optimum performance. This alignment process is particularly important for long-range point-to-point links. In a point-to-multipoint configuration the root bridge uses an omnidirectional or sector antenna, which does not require alignment, but bridge nodes still need to be correctly aligned with the root bridge antenna. -
