Removing and Installing a PRP
If you are replacing a PRP, disconnect any devices that are attached to the Ethernet, console, or auxiliary
Step 4
ports. If you are removing a PRP for maintenance and will reinstall the same one, you can leave the
devices attached, provided that doing so will not strain the cables.
Using a 3/16-inch flat-blade screwdriver, loosen the two captive screws on the ends of the PRP.
Step 5
Step 6 Place your thumbs on the ends of each of the ejector levers and simultaneously pull them both away from
the PRP faceplate (in the direction shown in
and to dislodge the PRP edge connector from the backplane.
Grasp the PRP faceplate handle with one hand and pull the PRP straight out of the slot, keeping your
Step 7
other hand under the PRP to guide it. Keep the PRP edge connector parallel to the backplane.
Avoid touching the PRP printed circuit board, components, or any edge connector pins.
Caution
Place the removed PRP on an antistatic mat or foam. If you plan to return the PRP to the factory,
Step 8
immediately place it in an antistatic bag to prevent ESD damage.
Installing a PRP
When you install a PRP, be sure to use the ejector levers, which help to ensure that the PRP is fully
inserted in the backplane connector. (See
inward (toward the center of the PRP), the ejector levers push the PRP into the slot and ensure that the
PRP backplane connector is fully seated in the backplane.
A PRP that is only partially connected to the backplane can halt the system.
Caution
To install a PRP, follow these steps:
Turn off system power.
Step 1
Attach an ESD-preventive wrist strap and follow its instructions for use.
Step 2
Step 3 Grasp the PRP faceplate handle with one hand and place your other hand under the carrier to support and
guide it into an upper card cage slot.
Avoid touching the PRP printed circuit board, components, or any edge connector pins.
Caution
Place the bus-connector edge of the PRP in the appropriate slot and align the notches along the edge of
Step 4
the carrier with the grooves at the top and bottom of the slot.
While keeping the PRP edge connector parallel to the backplane, carefully slide the carrier into the slot
Step 5
until the PRP faceplate makes contact with the ejector levers, then stop.
Using the thumb and forefinger of each hand to pinch each ejector lever, push both ejectors
Step 6
simultaneously toward the center of the PRP faceplate until they are perpendicular to the PRP faceplate.
(See
Step 7 Using a 3/16-inch flat-blade screwdriver, tighten the captive screws on the ends of the PRP. The captive
screws prevent the PRP from becoming partially dislodged from the backplane and ensure proper EMI
shielding. (These captive screws must be tightened to meet EMI specifications.)
