Connecting Power to a DC-Powered MX2000 Router with DC Power Distribution Modules (240 V China)

 Warning

Before performing DC power procedures, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position.

You connect DC (240 V China) power to the router by attaching power cables from the external DC power sources to the DC power cable that is connected to the PDM. The power cables are orderable (CBL-PWR-240V-CH).

To connect the DC (240 V China) source power cables (CBL-PWR-240V-CH) to the router:

  1. Switch off the dedicated customer site circuit breakers. Ensure that the voltage across the DC power source cable leads is 0 V and that there is no chance that the cable leads might become active during installation.
  2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.Note

    If the DC PSMs (240 V China) are installed in the router, make sure the power switches on all PSMs are turned to the off (O) position.

  3. Plug the power cord into the power sockets on the DC PDM (240 V China). Refer to Figure 1. Apply slight pressure so that the power cord is firmly seated in the power socket until you feel it engage. As you plug in each power cord, the power LED for the socket lights up green.
