Step 7: Perform Condence Test (Optional)
This step allows you to verify the equipment’s operation and test a wireless link
between the BSU and SU prior to the actual installation. If you wish to proceed
without performing a condence test, continue to Step 8: Mount the Unit.
To perform a condence test:
Place the units on a tabletop or shipping box, positioning them at least 10
feet from each other. If the units are too close together, the radio signal
from the antennas may be too strong to get good reception, resulting in
a bad quality due to distortion in the receiver. Do not aim the antennas at
each other, as this may cause too high a signal level.
Plug one end of the CAT5 cable into the RJ45 jack of the BSU.
Connect the free end of the CAT5 cable to the “Data and Power Out” port
on the power injector.
To connect the BSU through a hub or a switch to a PC, connect a straight-
through Ethernet cable between the network interface card in the PC and
the hub, and between the hub and the RJ45 “Data In” port on the PoE
adapter.
To connect the BSU directly to a PC, connect a cross-over Ethernet cable
between the network interface card in the PC and the RJ45 “Data In” port
on the power injector.
Repeat steps 2 through 4 for the SU.
Connect the power injector cord for each unit into an AC outlet. When the
units are powered on, they perform startup diagnostics. When startup is
complete, the wireless LED should briey blink green and turn solid green
when the wireless link between the two units is established.
Verify that the SNR (Signal to Noise Ratio) is no more than 50 dB to
guarantee a good reception. The SNR is displayed in the Link Test and Per
Station monitoring Web interface pages, and also displayed on the serial
port through the CLI when the serial dongle is plugged into the unit. If the
SNR is greater than 50 dB, reposition the units.
Verify that the network connection is working correctly (by accessing the
Web or e-mail).
When all tests have passed successfully, the wireless point-to-point bridge
is ready to be installed.
Proxim recommends that the BSU be installed at the location from where you
expect the wireless network to be extended in the future.
