Hardware Warning

This type of event is one that may be affecting the performance or lifespan of a component, e.g.
temperature, voltage or current limits, fan failure, etc.
2020-04-01 09:51:29: Raised hardware warning alarm: Fan fault (PH) on PH PSU
In each case of a hardware warning the unit identity is included in the message.
This condition can also be cleared if you disable the faulty component (where possible) through the
System Setup window or Apply a new set of parameters that disable the potentially affected service(s)
at the affected location(s). For Hardware warnings this condition is also self-cleared by the Hub if the
component returns within limits.

Description
The uplink gain is potentially
greater than the downlink gain.
The system cannot achieve the
required output with the input
level set on the Set-Up page.
The system has a maximum
gain of 25 dB between service
level input and Remote Unit
output power settings.
The system has detected that
there are inconsistencies with the
automatic setting of the internal
system parameters due to
inequalities in connected
components.
Description
In each case the unit affected will
be included in the log message
Example "The module temperature
is above the upper limit" on PH
PSU.
The cause will be the ambient
temperature of the device in
question.
Understanding Alarms & Reporting
Action
The system will automatically set the
uplink gain to be the same as the
downlink gain with a UL/DL balance of
0, but will show this condition indicating
that the UL /DL balance can be
adjusted if required.
If the value provided at System Setup
requires greater than this the input value
will be adjusted while maintaining the
requested output power. The delivered
input power should be adjusted (raised)
to ensure that excessive gain is not
required.
This should not prevent satisfactory
operation, but values for all elements
connected to the affected Matrix should
be checked (RU output etc power and all
optical links should be checked to
ensure that they are performing inside
optical limits.)
Action
Adjust the temperature or trace the
specific problem through the
equipment. See specific over and
under temp alarms below.
