Possible Cause
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.
2. Ethernet port in unit
is faulty.
Corrective Action
1. Verify power to units.
2. Verify that all cables are
connected securely.
3. Refer to the previous section and
verify wireless link between the units.
4. Verify that the antenna(s) are
properly installed:
• 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 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 the unit
is working. Ping the 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).
