Connecting AC Power to an MX2000 Router with Three-Phase Wye AC
Power Distribution Modules
CAUTION: Do not mix AC and DC power distribution modules (PDMs) within the
same router.
WARNING: Power connections must be performed by a licensed electrician only.
To connect an AC power cord to an AC power source:
1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to
an approved site ESD grounding point. See the instructions for your site.
2. Switch off the dedicated customer-site circuit breakers. Ensure that the voltage across the AC power
source cable leads is 0 V and that there is no chance that the cable leads might become active during
installation.
3. Detach the ESD grounding strap from the approved site ESD grounding point, and connect the strap
to one of the ESD points on the chassis.
4. Move the power switches on all the power supply module (PSM) faceplates to the off (O) position.
5. Verify that the correct three-phase wye PDMs are installed and secured in the chassis before connecting
power cables.
NOTE: The power cables must be uninstalled and removed from the three-phase wye
PDM before removal of the PDM from the chassis.
6. Using a number 2 Phillips (+) screwdriver, unscrew the four captive screws located on the either side
of the metal AC wiring compartment (four screws total on each PDM).
7. Remove the metal cover of the metal AC wiring compartment.
8. Unscrew the retaining nut from the AC power cord.
