  1. 1.0 1.1 1.2 1.3 This is accomplished by running openssl speed which generally consumes 100% CPU time
  2. 2.0 2.1 2.2 2.3 Using iperf to create bidirectional activity which adds minor CPU load


1.1 TS-SILO Power Consumption

The TS-8551-4100 supports TS-SILO Supercapacitors for back-up power in the event of a power loss. Charging of the supercapacitors causes a change in overall power consumption of the whole system. Because of this, the numbers below are the average curve and peak power draw during a full charge cycle of the TS-SILO technology itself. In other words, the power noted below is separate from the numbers listed above and should be added to the numbers above to sum the total power draw of the whole device.

The current consumption of TS-SILO supercapacitors is not linear during charging. The charge process has a curve to it and the maximum average current consumption is near 80% of full capacity. Below we document the average average over the whole curve and the peak consumption that could be seen.
