Replace A Pa-7080 Dc Pem - PaloAlto Networks PA-7000 Series Hardware Reference Manual

Replace a PA-7080 DC PEM

The DC Power Entry Module (PEM) is located on the back of the chassis and connects the power source
to the power supplies located on the front of the chassis, which then distributes power to all chassis
components.
The PEMs are not hot swappable. You must power off the chassis, turn off the DC power
feed, and remove the DC power cables from the failed PEM before proceeding. The PEMs
on the AC model are not field serviceable.
STEP 1 | Put the provided ESD wrist strap on your wrist ensuring that the metal contact is touching your
skin. Then attach (snap) one end of the ground cable to the wrist strap and remove the alligator
clip from the banana clip on the other end of the ESD grounding cable. Plug the banana clip
end into one of the ESD ports located on the front of the chassis before handling ESD sensitive
hardware. For details on the ESD port location, see
STEP 2 | Power off the chassis and disconnect the power source to the chassis.
STEP 3 | Remove the stud nuts and star washers from the DC studs that secure the DC cables to the
PEM and then remove the cables.
STEP 4 | Remove the eight screws that secure the PEM to the chassis.
