Figure 1–4. Aligning the MP-632 Antenna According to Signal Strength
When aligning the antennas the MP with the antenna that is being aligned to must be set to send
link-calibration packets. Use the following command to setup the MP that the MP-632 is being
aligned with.
set ap num radio num link-calibration mode {enable | disable}
Link-calibration should be disabled under normal operation of the MP.
If the MP-632 is installed with two directional antennas, connect the first antenna to the primary
antenna port with antenna diversity off and align it. Then disconnect the first antenna and connect
the second antenna to the primary antenna port. If the second antenna is being aligned with a
different MP, disable link-calibration on the original MP and enable it on the new MP. Once both
antennas are properly aligned, connect them to their desired ports.
RSSI Meter Functionality
The MP-632 supports an LED-based RSSI indicator when either radio operates in mesh link
calibration mode. The RSSI reading must be able to support the indication of received signal levels
across a 35dB dynamic range, from a high of -60 dBm to a low of -95 dBm.
The RSSI is indicated by on/off/flashing LED patterns, as shown in the table below. The granularity
varies between 2dBm, 3dBm, and 6dBm.
