Connecting Power to an MX2000 Single-Phase AC Power Distribution
Module
CAUTION: Do not mix AC and DC power distribution modules (PDMs) within the
same router.
To connect an AC power cord to a single-phase seven-feed or nine-feed AC power distribution module
(PDM):
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 switch to the off (O) position on the PSM(s) that will be powered by the AC PDM.
NOTE: After powering off a PSM, wait at least 60 seconds before turning it back on.
5. If a power cord retainer is installed on the PDM, remove the two thumb screws holding it in place and
remove the power cord retainer.
6. Plug the power cords into the power sockets on the PDM. Refer to Figure 128 on page 301 . Apply slight
pressure so that the power cords are firmly seated in the power socket. As you plug in each power
cord, the power LED for the socket lights up green.
