Powering Up the PacketWave 200
WARNING: For the PacketWave 200, use an outlet that contains surge protection and
ground fault protection, or use a surge protection device. This will protect
the PacketWave 200 and equipment connected to it from damage result-
ing from AC current surges, lightning, etc. For complete protection, all
connections to the PacketWave 200 should be connected to a surge pro-
tection device. To ensure the best signal, use surge protectors designed
for the specific application.
To apply power to the PacketWave 200:
1. Plug the power cord into the connector on the transformer connector to the Inter-
face Box.
2. Plug the power cord into a surge-protected AC outlet.
The PacketWave 200 does not have an on/off switch; to turn the unit off, disconnect power
at the power outlet.
NOTE: The ODU receives power from the Interface Box via the Ethernet cable.
Aligning the Antenna Using Audio Auto-Alignment Mode
For the audio auto-alignment mode to function, the PacketWave 200 must be pre-
provisioned prior to installation using the Aperto Installation Manager (AIM) in Provi-
sion mode, as described in Chapter 5. If preconfiguration has not been performed,
use the AIM for antenna alignment as detailed in Chapter 5
When power is applied to a pre-configured PacketWave 200, the ODU will begin slowly beep-
ing. The beep is an audio indication of the strength of the signal received from the base sta-
tion. As reception gets stronger (within the range from -50 dBm to -100 dBm), beeping
increase in pitch and frequency, becoming a continuous tone when the signal is optimal.
To optimize antenna alignment using the audio auto-alignment mode:
1. Adjust the position of the ODU for the highest pitch and frequency of the beeping,
ideally finding a position which results in a continuous tone. Secure the ODU in
that position.
2. When the ODU receives a continuously strong signal for one minute (specifically,
when the signal-to-noise ratio is higher than 16 dB and the signal strength is greater
than -88 dB without varying by more than 2 dB for one minute), the PacketWave 200
will become operational with an audio tone similar to a telephone ringing.
3. If such a signal is not obtained, the audio signal will continue until power is removed,
and the PacketWave 200 will not become operational. Antenna alignment will need
to be performed using the Aperto Installation Manager as described in Chapter 5.
