Problem Type Message Icon Impact
Loose connec-
tor, shorted con-
ductor or
improper con-
nection to the
shield.
None
High phase noise, degraded signal on both
Downlink and Uplink (high bit error rate)
• No communication with RAUn
RAU unable to communicate with Hub,
degraded performance or RAU off-line
• Portn UL RF path loss is too high
Increased ripple in the uplink path, decreased
UL gain, or no UL gain
• The DL RF path loss is too high
Increased ripple in the downlink path, RAU
off-line
•RAUn over current or port short
RAU will not power on.
