Powering On the DC-Powered (240 V China) MX2000 Router

To power on a DC-powered router:
1. Verify that an external management device is connected to one of the Routing Engine ports on the
Control Board and Routing Engine (CB-RE) (AUX, CONSOLE, or MGMT).
2. Turn on the power to the external management device.
3. Verify that the PDMs are fully inserted in the chassis.
4. Verify that the source power cables are connected to the PDM power cable.
5. Switch on the dedicated customer site circuit breakers to provide power to the DC power cables. Follow
your site's procedures.
6. Check that the input labeled LEDs are lit green steadily, indicating the PDMs are installed and functioning
normally.
NOTE: Nine input LEDs indicate proper voltage level and polarity of input feeds.
7. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to
one of the ESD points on the chassis.
8. For each of the DC PDMs installed, switch the DC circuit breaker at the power source, moving it to
the (ON) position.
9. On each of the DC PSMs, move the switch to the on (|) position.
10. Verify that the PWR OK LED is lit green steadily, indicating the PSM is correctly installed and functioning
normally.
NOTE: After a PSM is powered on, it can take up to 60 seconds for status indicators—such
as the status LEDs on the PSM and the show chassis command display—to indicate that
the PSM is functioning normally. Ignore error indicators that appear during the first 60
seconds.
