8.3 Troubleshooting
NOTE: Unison has no user-serviceable parts. Faulty or failed units are fully
replaceable through LGC Wireless.
Sources of potential problems include:
• Faulty cabling/connector
• Malfunction of one or more Unison Accel components
• Antenna, base station, or repeater problem
• External RF interface
• Tripped circuit breaker
• Using a Null modem cable that does not support full hardware handshaking when
using AdminManager
NOTE: Faulty cabling is the cause of a vast majority of problems. All
Cat-5/6 cable should be tested to TIA/EIA 568-A specifications.
You must use AdminManager for troubleshooting the system, only use the LEDs as
backup or for confirmation. However, if there are communication problems within
the system, the LEDs may provide additional information that is not available using
AdminManager. The only problem that is indicated solely by the LEDs is when a
band is not programed in the Accel Hub. In that case, the LEDs flash continuously,
beyond the normal system check flashing upon power up.
If you cannot determine the cause of a problem after following the recommended pro-
cedures, call LGC Wireless customer help hot line:
