Connecting Power Cords - H3C S12508-AC Installation Manual

Connecting power cords

Prerequisites
Follow these guidelines before connecting power cords:
For lightning protection, the AC power should be led through an external lightning device into
•
S12500 Routing Switch Series. For more information, see the chapter "Appendix D Lightning
protection."
Make sure the power switch on the power frame is in the OFF position.
•
For personal and switch safety, do not connect the power cords with the power. Power off the
•
grounding strip, connect the power cords, power on the grounding strip, and then power on the
switch.
Connecting an AC power cord
Each socket on a PEM (LSTM2PEMC6) corresponds to a power module slot. Sockets numbered 1 through
6 provide power module for the power modules in slots 1 through 6, respectively. If slot 1 is installed with
a power module, the number 1 receptacle on the PEM must be connected to a power source with an AC
power cord to make the power module operate properly.
CAUTION:
Typically 10 A busbars are available in the equipment room but the PEM on the S12500 (LSTM2PEMC6)
requires a 16 A power cord (AC), so you need to use a 16 A busbar, and ensure that the AC power
module system can provide enough power. For AC power cords used in different countries or regions, see
the chapter "Appendix A Technical specifications."
To connect power cords:
Remove the strain-relief screws of the power cord retention clip, and remove the retention clip.
1.
Insert the connector of the AC power cord into the PEM receptacle.
2.
Install the retention clip to the connector and fasten the screws to lock the power connector.
3.
Connect the other end of the AC power cord to the power source.
