Replacing an NRP Module
Removing an NRP-2SV Module DIMM
To remove a DIMM:
Step 1
Attach an ESD-preventive wrist strap between you and an unpainted chassis surface.
Step 2 Disconnect the cables from the NRP-2SV.
Step 3
Loosen the captive installation screws on the NRP-2SV module and remove it from the chassis.
Step 4 Place the NRP-2SV on an antistatic mat or pad. Position the NRP-2SV module, so that the faceplate is
away from you and the edge connector is toward you.
Step 5
Locate the DIMMs on the NRP-2SV module ( Figure 5-20 ).
Note
Be sure to note the orientation of the DIMM in the socket. The card is notched so that it can
be inserted only one way to align the notches on the DIMM with the socket. When you insert
the new NRP-2SV, align the new DIMM the same as the old DIMM to avoid damaging the
unit and to ensure proper operation.
Step 6
Pull the levers on the socket to the “outside” to release the DIMM, and then lift the DIMM from the
socket.
Step 7
When both ends of the DIMM are released from the socket, use your thumb and forefinger to grasp the
ends of the DIMM and pull the DIMM completely out of the socket. Handle the edges of the DIMM only;
avoid touching the memory module, pins, or metal traces (fingers) along the socket edge.
Step 8
Place the DIMM in an antistatic bag to protect it from ESD damage.
Installing the NRP-2SV Module DIMM
To replace the DIMM:
Step 1 Keep the NRP-2SV in the same orientation as in the previous procedure (with the handle facing away
and the edge connector toward you).
Step 2
Remove a new DIMM from the antistatic bag.
Caution Handle DIMMs by the card edges only. DIMMs are sensitive components that can be shorted by
mishandling.
Step 3 Align the new DIMM to the same orientation the old DIMM was in when you removed it from the socket.
Step 4
Hold the sides of the DIMM between your thumb and middle finger, with your forefinger against the far
edge, opposite the connector edge.
Step 5 Align the two notches on the DIMM with the socket and insert the connector edge into the socket.
Step 6
Gently push the DIMM into the socket until the notches on the DIMM align with the levers on the socket.
The DIMM will “click” into place. The DIMM is “self-locking” when properly seated.
