After all connections, including fiber, have been established, apply power to the GX2-HSG*. Power
connections are in the rear of the equipment shelf as illustrated in Figure 3-1.
Using the supplied cable, provide power from a source voltage of 105 VAC to 264 VAC to the AC
input connector on the rear of the GX2-PSAC10D-R as illustrated in Figure 3-2:

Before removing a power supply from the GX2-HSG*, disconnect the power input cable from the
rear of the GX2-PS*10*. If a GX2-PS*10* is removed before power is disrupted, you must wait
approximately five minutes before restoring power or the unit may not start properly.
In normal operation, it is not necessary to remove power from the equipment shelf when installing a
new module or replacing one. The shelf and all modules are designed to enable module replacement
with power applied.

The AC input voltage, which must be between 105 Vrms and 264 Vrms, is filtered and then applied
to a power-factor control circuit that converts the AC voltage to DC. The high voltage DC is applied
to three DC/DC converters. The converters, one for each of the three output voltages, supply
precisely regulated output voltages of +5.1, +12, and +3.7 VDC respectively. Short circuit protection
is provided by each of the DC/DC converters to limit the output current until the fault is cleared.
