NOTE:
Each PSM slot not occupied by an AC PSM must be covered by a
PSM blank panel.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
1.
the strap to one of the ESD points on the chassis. For more information about ESD,
see the MX2008 3D Universal Edge Router Hardware Guide.
NOTE:
If the DC PSMs are installed in the router, make sure that the power
switch is turned to the off (
Ensure that the voltage across the DC power source cable leads is 0 V and that there
2.
is no chance that the cable leads might become active during installation.
Remove the DC PDM from the electrostatic bag.
3.
Using both hands, slide the PDM part way into the chassis.
4.
Open the two locking levers on either side of the PDM, and align them with the openings

in the chassis.
Using both hands, push firmly on both spring-loaded levers until the PDM is fully seated

in the chassis slot. The PDM faceplate should be flush. Tighten both captive screws.
NOTE:
Make sure that the DC circuit feed switch on the PDM faceplate
matches the current rating amperage—
to all inputs of this PDM, and selecting 60 A reduces the available power
output capacity of the PSMs supplied by this PDM.
