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 install a DC power distribution module (PDM) in an MX2000 Router:
1. 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.
Before performing DC power procedures, disconnect all power sources.
