2.5 Powering Up
Midspan is powered by the power cord. In order to apply or remove power to/from the Midspan,
connect or disconnect the AC power cable to/from the AC power connector on the rear side of
the unit.
With AC power applied, the unit starts-up and the internal fans are active. The device runs
through a quick power-on test, which takes less than 10 seconds. During this period, all ports are
initially disabled and the port indicators light up. The sequence of the port LEDs are shown in
section 2.6 LED Indicator – Cold Start. Ports are now operating under normal conditions.
