User's Guide
Possible Cause
1. Power supply to units
may be faulty.
2. Cables may be
improperly connected
3. There may be some
problem with antenna
installation.
1. Ethernet hub port or
UTP cable is faulty.
Ethernet port in unit is
faulty. The station is
associated to a BU-
DS.11 unit that is not
connected correctly to
the LAN
Corrective Action
1. Verify power to units.
2. Verify that all cables are connected
securely.
3. Refer to previous Section and verify
wireless link between the units.
4. Verify that the antenna(s) are properly
installed (see relevant section in this manual):
Check antenna alignment.
Verify that antenna polarization is the
same at both ends.
Verify that the range matches
specifications.
Verify line-of-sight/antenna
alignment/antenna height.
1. Check that the LINK LED is lighted Green.
If this is not the case, the port is inactive. Try
another port on the hub or another UTP cable.
2. Verify that Ethernet port in unit is working.
Ping unit to verify Ethernet connection.
3. Verify that you are using a cross-over UTP
cable (pins 1 & 3, 2 & 6) if connected directly
to workstation, or a straight-through cable if
connected to a hub.
4. Check the unit's LINK LED indicator and
check the Ethernet counters in the monitor to
verify Ethernet activity (see Section 3.3.4).
Check that there is no other BU-DS.11 that
has the same channel and ESSID, but is not
connected to the LAN.
