9.4 Troubleshooting CAT-5/5E/6
Refer to Table A-1 on page A-1 for a description of the CAT-5/5E/6 wire assignment.
The following table summarizes
CAT-5/5E/6 problems if a wire is cut or not wired
properly.
Table 9-14 Summary of Cat-5/5E/6 Cable Wiring Problems
Type of
problem Message Icon 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 EH,
decreased UL gain, or no UL gain
Wire 4 or 5 cut Portn UL RF path loss is too high Increased ripple in the uplink path,
decreased UL gain, or no UL gain
Portn UL RF path loss is higher
than recommended
Wire 7 or 8 cut The DL RF path loss is too high Increased ripple in the downlink path,
RAU off-line
The DL RF path loss is higher than
recommended
Wire 1 to RJ-45
pin 3 or 6
No communication with RAUn RAU unable to communicate with EH,
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 EH,
