wireless link (“D”
models/external
antennas)
1. Power supply to
units may be faulty.
2. Cables may be
improperly connected
3. There may be some
problem with antenna
installation.
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

Wireless link
established, but there
is no Ethernet
activity (BU-DS.11
and RB-DS.11 units).
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
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

). Check that there is no
other BU-DS.11 that has the same channel
and ESSID, but is not connected to the
LAN.
