3.4 Powering On the Unit

The PoE Gigabit Injector receives power via the power cord. To apply or remove power to/from the PoE Gigabit Injector, connect or disconnect the AC power cable to/from the AC power connector on the rear 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 3.5. Ports are now operating under normal conditions.
