Connecting an MX2000 DC Router Power Distribution Module (240 V
China) Cable
WARNING:
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.
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. Press
the latch on the side of the power cable before pushing it in. 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.
Before performing DC power procedures, disconnect all power sources.
