Description
This indicates a problem with the
power supply rails of the device in
question. In the case of Optical
Modules, Service Modules and Hub
alarms it relates to the Hub Power
supply. If the alarm is raised in
conjunction with a Remote Unit, the
fault will be with local unit or the
centralized feed.
These are Hub alarms indicating
problems with the Hub power
supply. Some are used directly by
modules and others are
intermediate step-down voltages.
The fan speed is monitored as
part of the internal control of the
Hub. A fan fault will either
indicate a power supply issue or
functional problem with the fan.
The received optical power is
below the minimum threshold for
satisfactory operation and will
result in any connected modules
being disconnected/ deleted. The
problem can be either a power
failure at the far end or a break in
the optical fiber cable.
The optical power level exceeds
the maximum value in the case
of an optical link or if reported in
conjunction with a Remote Unit
indicates that the overload value
for the RU has been exceeded.
Understanding Alarms & Reporting
Action
If the issue persists, contact Support and
arrange for unit RMA in accordance with
your maintenance and support
agreement.
Check for build-up of dirt and dust and
replace as required.
Check the optical connection and
fibers for damage, cleanliness and
poor connection. If necessary, clean
both sides of the optical interface
carefully or replace if damaged.
Remove the overload condition
