Chassis Cooling
The fans on the GigaVUE TA Series-TA100 run at 100% of their maximum speed on power
up, then drop to approximately 60% during normal operations. The temperatures of four
components: transceivers, exhaust, CPU, and switch CPU, are monitored. When a
component crosses a pre-defined threshold, the fan speed is adjusted dynamically, in
increments of approximately 10%.
An SNMP trap is sent when a component reaches the threshold for warning, alert, or
critical temperature conditions. Refer to
Table 5: Component Temperature Thresholds
for the temperatures at which the warning, alert, and critical traps are sent
and any additional action that occurs at a threshold.
