Connecting a DC power cord
Six pairs of wiring terminals (marked PSR1 through PSR6) are available on the DC grounding strip of the
S12500 switches. The wiring terminals correspond to the power supplies 1 through 6, respectively. The
power source supplies power to the switch through the wiring terminals. If slot 1 is installed with a power
supply, the wiring terminals marked PSR1 must be connected to the power source with a DC power cord
to make the power supply operate properly.
CAUTION:
A plastic protection cover is installed in front of the grounding strip to protect operators from being
shocked. Remove the protection cover before connecting power cords and then install the protection cover
in time.
To connect a DC power cord:
1. Remove the protection cover from the power supply.
