To connect DC power cords:
1. Loosen the screws on an RTN(+) terminal (PWR1, for example) on the terminal block, and remove
the screws.
2. As shown in Figure 30 , use screws to secure the terminal of the black DC power cord to the RTN(+)
terminal.
3. Use the same method to connect the terminal of the blue DC power cord to the NEG(-) terminal.
4. Connect the other ends of the DC power cords to the power source and switch on the circuit
breaker.
{
Blue DC power cord —–48V terminal.
{
Black DC power cord —RTN terminal.
5. Connect all power cords, and turn on the power switch to the left of the power receptacles.
6. Examine the power module input/output status LEDs.
If all the LEDs are on, the power cords are correctly connected. For description of power module
status LEDs, see "
Appendix C LEDs ."
7. Install the plastic panel to the air inlet vents at the lower part of the front panel. For installing the
plastic panel, see " Installing the switch ."
Figure 30 Connecting DC power cords
(Optional) Installing a DC input terminal block
For an S12500-X DC switch, if the power distribution box is far away from the rack, you can order an
extension cable and a DC input terminal block to supply power to the device.
A DC input terminal block provides eight pairs of terminals. Each pair uses two wires to provide DC
power supply. A maximum of eight pairs of wires are supported. The terminals support cables with a size
of 10 mm² to 35 mm² (0.02 sq.in to 0.05 sq.in)
