Problem and Indication Possible Cause Corrective Action
Failure to establish 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
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.
Wireless link established,
but there is no Ethernet
activity (AP and WB units).
1. Ethernet hub port or
UTP cable is faulty.
2. Ethernet port in unit is
faulty.
1. Check that the LINK LED is on and
solid at the hub port. 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 ETHR LED indicator in unit and
Ethernet counters in Monitor to verify
Ethernet activity (see Section 3.6.1).
Wireless link established,
but there is no Ethernet
activity (SA-10 and SA-40
units).
1. Ethernet port on
Network Interface card is
faulty.
2. Ethernet port of unit is
faulty.
3. UTP cable is faulty.
1. Verify that the LINK LED is lit and solid
at the NIC port. If this is not the case, the
port is inactive. Try using another UTP
cable or another workstation.
2. Ping the unit to check the Ethernet port.
If you cannot ping the unit, this may
indicate failure of cable, Ethernet port of
unit or Ethernet port of workstation’s NIC.
Change UTP cable and retry. If you still
cannot ping the unit, exchange units and
try to ping the new unit using the same
NIC and cable.
