Powering On a Three-Phase AC-Powered MX2000 Router
You can use this procedure for a router with either a three-phase delta AC power distribution module
(PDM) or a three-phase wye AC PDM.
1. Verify that the power supply modules (PSMs) are fully inserted in the chassis and that the captive
screws on their faceplates are tightened.
2. Verify that the PDMs are fully inserted in the chassis and that the captive screws on their faceplates
are tightened.
3. Verify that each AC power cable is properly connected.
4. Verify that an external management device is connected to one of the Routing Engine ports on the
CB-RE (AUX, CONSOLE, or MGMT).
NOTE: The management Ethernet port is not functional until you have completed the
initial configuration.
5. Turn on power to the external management device.
6. Switch on the dedicated customer-site circuit breakers to provide power to the AC power cables. Follow
your site’s procedures.
7. Verify that the LEDs on both PDM and PSM light green steadily.
If any of the status LEDs indicates that the PDM is not functioning normally, repeat the installation and
cabling procedures.
8. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to
one of the ESD points on the chassis.
9. Move the power switch on one of the PSMs to the on (|) position. The OK LED blinks momentarily,
then lights steadily.
