Recovery of the link failure results in a similar set of actions to indicate that the
failure event cleared. Note that a failure of the transport line or a failure of the
opposing host on the wireline link will both appear to the base radio as a link failure.
The base radio cannot distinguish between these two cases.
In the event the base radio detects a hardware issue with the transceiver option card,
when used for analog and mixed mode operation, it will:
1. Log an occurrence of the failure in the base radios local event log, which is
retrievable through the configuration interface.
2. If connected to centralized fault management equipment (optional), then
the base radio transmits an alarm indication to the fault manager to alert the
system administrator of the failure. The alarm will be associated with the
base radios control module.
3. A local visual indication is active due to this failure.
In the event the fan assembly malfunctions, the base radio will:
1. Log an occurrence of the failure in the base radios local event log, which
is retrievable through the configuration interface
2. If connected to centralized fault management equipment (optional), then the
base radio transmits an alarm indication of "warning" severity to the fault
manager to alert the system administrator of the failure. The alarm will be
associated with the base radios control module.
3. The base radio provides a local visual indication associated with the failure.
4. In the event the base radio detects the maximum operable temperature has
been exceeded, then the base radio transitions to a critical malfunction state,
log the state change, and generate a fault indication if connected to the UEM.
The following conditions must be met to obtain a power consumption of less than
or equal to 35 W:
• DC source only
• Speaker turned OFF (if equipped with a transceiver option card)
• No activation of Aux Out Relays (if equipped with a transceiver option card)
• No 29 V AUX loads. For example, active draws by a site controller.
• CSS configured for applications not requiring receiver diversity
• CSS Fan Holdover configured to "short" (length of time the base radio fan
stays ON after transmission)
• Ambient temperature of 104 °F (40 °C) or less (single fan operation –
disabling one of the fans within the fan module. See
Assembly, page 9-10for instructions on how to disable the fan.)
