Powering Off the DC-Powered MX2000 Router

NOTE: After powering off a PSM, wait at least 60 seconds before turning it back on.

move the DC circuit breaker from the power source input for each DC PDM to the (OFF) position.

operational mode command individually on both the RCBs. The command shuts down the RCB cleanly,
