5.12 Alarms Page
The Alarms Page provides an easy-to-read summary of the alarm status of both the local and
remote radio. Generally, the colors shown on this page will reflect the color of alarms that are
shown on the radio front panel. However, additional detail is illustrated on this page to aid in
quick assessment of issues and status.
Refer to section 4.1.2 for more information about the front panel LEDs. Additional information
about the Alarm status is provided here.
• The Internal Fan alarm monitors all three internal fans. The radio only requires one
fan to be operational for full specification performance. The additional fans are
provided for redundancy and to increase overall reliability. If one or two fan alarms
are yellow or red, it is prudent to plan to install a spare radio at the earliest opportunity
and return the radio for repair (RMA authorization required). If all three fans are in
alarm, the radio should be taken out of service more immediately, as damage may
occur to the internal electronics, especially in hotter ambient environments or thermal
exchange from neighboring equipment.
• The Temperature alarm monitors the internal temperature of the unit, based on
specific points inside the radio chassis. It is normal for the internal temperature to be
above the ambient temperature, and thus the temperature may be higher than the
highest specified ambient temperature. When the internal electronics reach a point that
is higher than the normal temperature rise at the highest ambient temperature, the
temperature alarm will turn to yellow. In this case, the radio should be powered down
as soon as possible, and an investigation as to the cause of the temperature rise should
commence and be resolved before the radio is put back into service. In almost all
cases, a temperature alarm will be due to an external cause, unless the fans in the unit
are also in alarm, in which case, the alarmed fans are likely the cause.
