Connecting Power to a High Voltage-Powered MX2000 Router with Power Distribution Modules

 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.

Note

Ensure that you have connected the chassis to earth ground. See Grounding an MX2000 Router.

You connect AC or DC power to the router by connecting the power cord from a universal (HVAC/HVDC) PDM to an AC or DC power source. See MX2000 High-Voltage Universal PDM (MX2K-PDM-HV) Power Cord Specifications for the list of supported power cords.

To connect the DC or AC source power cables to the router:

  1. Switch off the dedicated customer site circuit breakers. Ensure that the voltage across the AC or 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 PSMs 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 high-voltage second-generation universal (HVAC/HVDC) PDM . See 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.
