Refer to Table A-1 on page A-1 for a description of the Cat-5/6 wire assignments.
The following table summarizes Cat-5/6 problems if a wire is cut or miswired.
Table 8-9 Summary of Cat-5/6 Cable Wiring Problems
Type of
problem Message Icon Impact
Wire 1 or 2 cut None High phase noise, degraded signal on both
Downlink and Uplink (high bit error rate)
Wire 3 or 6 cut • No communication with RAUn RAU unable to communicate with Hub,
degraded performance or RAU off-line
Wire 4 or 5 cut • RAUn uplink AGC failure Increased ripple in the uplink path,
decreased UL gain, or no UL gain
• Cat-5/6 cable between RAUn and Hub is
longer than recommended
Wire 7 or 8 cut • Downlink pilot failure Increased ripple in the downlink path,
RAU off-line
• Cat-5/6 cable between RAUn and Hub is
longer than recommended
Wire 1 to RJ-45
pin 3 or 6
• No communication with RAUn RAU unable to communicate with Hub,
RAU’s RS-485 port damaged, degraded
performance or RAU off-line
Wire 1 to RJ-45
pin 4, 5, 7 or 8
•RAUn over current RAU will not power on.
Wire 2 to RJ-45
pin 3 or 6
• No communication with RAUn RAU unable to communicate with Hub,
RAU’s RS-485 port damaged, degraded
performance or RAU off-line
Wire 2 to RJ-45
pin 4, 5, 7 or 8
•RAUn over current RAU will not power on
Wire 3 to RJ-45
pin 4, 5, 7 or 8
• No communication with RAUn RAU unable to communicate with Hub,
degraded performance or RAU off-line
Wire 6 to RJ-45
pin 4, 5, 7 or 8
• No communication with RAUn RAU unable to communicate with Hub,
degraded performance or RAU off-line
Wire 4 to RJ-45
pin 7 or 8
•RAUn uplink AGC failure Increased ripple in the downlink and
uplink path, degraded performance or
RAU off-line
• Downlink pilot failure
• Cat-5/6 cable between RAUn and Hub is
longer than recommended
