Prerequisites
Follow these steps 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 of the switch."
• 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 supply slot. Sockets numbered 1 through
6 provide power supply for the power supplies in slots 1 through 6, respectively. If slot 1 is installed with
a power supply, the number 1 receptacle on the PEM must be connected to a power source with an AC
power cord to make the power supply operate properly.
CAUTION:
Typically 10 A busbars are available in the equipment room but the LSTM2PEMC6 requires a 16 A power
cord (AC), so you need to use a 16 A busbar, and ensure that the AC power supply system can provide
enough power. For AC power cords used in different countries or regions, see the chapter "Appendix A
Technical specifications."
Follow these steps to connect power cords:
Remove the strain-relief screws of the power cord retention clip, and remove the retention clip.
Step1
Insert the connector of the AC power cord into the PEM receptacle.
Step2
Install the retention clip to the connector and fasten the screws to lock the power connector.
Step3
Connect the other end of the AC power cord to the power source.
