RedMAX Administration and Maintenance Guide
Redline Communications Inc. Confidential and Proprietary
If you are using RMS to manage your network, then refer to the Redline Management Suite
User Guide for information on how RMS configures itself as the trap destination and
instructions on configuring alarm notification rules.
If you are using another trap receiver, then you need to configure each sector controller to
send SNMP traps to the your trap receivers and configure those applications to provide
notification.
Troubleshooting the GPS Clock Module
Management of the GPS clock module is performed via the local console port. There is no
remote access to the GPS. If a holdover condition is detected and not cleared, a technician
must be sent on-site to investigate. It may be necessary to reset the GPS clock module
and this can only be done locally.
The RedMAX GPS clock module does not require any periodic maintenance. You may only
encounter issues with the loss of satellite signal.
The following table lists symptoms and possible investigative/corrective actions for
antenna outages (red LED lit) and corresponding loss of signal.
Table 3-2
Troubleshooting Antenna Problems
Possible Cause
Investigative/Corrective Action
The antenna has been
knocked/blown down
Remount antenna dome within >5° of vertical.
There is excessive snow/ice/dust
buildup on the antenna
Clear off the antenna and ensure the antenna dome is within
>5° of vertical.
The antenna mount has failed.
Remount antenna dome within >5° of vertical.
Receiver fault
Check for the presence of ~ +4.85 to +5.15 VDC power from
the GPS receiver BNC output. If the voltage is below this
range, contact [email protected].
Lightning/EMP protection shorted
• Check for the presence of > +4.25 VDC at the antenna
side of the lightning/EMP protector BNC/TNC/Nm. The tip
= positive (+), Sleeve = negative (-).
• Remove the EMP and replace it with a joiner temporarily.
If the problem clears up occurs, replace gas tube
protection element, or replace the EMP, as required.
Cable fault
• Check for the presence of > 4.25 VDC at the antenna
coaxial connection. The tip = positive (+), Sleeve =
negative (-).
• Check the roof fly lead portion, roof demarcation
entrance, cable transits, conduits and clamps to make
sure the cables are not pinched or cut or damaged in any
way.
• Check all coaxial cable connections and crimps. Ensure
all exterior connections are weatherproofed as outlined in
the RedMAX Base Station Installation Guidelines
