d. Push down carefully, but firmly, on the top edge of the DIMM until the ejector tabs snap into place over
the notches at both ends of the DIMM.
e. Repeat substeps 7a through 7d for the remaining DIMMs.
8. Move the fans from the impaired NSM module to the replacement NSM module.
a. Firmly grasp a fan from the sides, where the blue touch points are located, and then lift it vertically to
disconnect it from the socket.
You might need to gently rock the fan back and forth to disconnect it before lifting it out.
b. Align the fan with the guides in the replacement NSM module, and then push down until the fan module
connector is fully seated in the socket.
c. Repeat substeps 8a and 8b for the remaining fans.
9. Close the cover of each NSM module, and then tighten each thumbscrew.
10. Move the power supply from the impaired NSM module to the replacement NSM module.
a. Rotate the cam handle to its open (horizontal) position, and then grasp it.
b. With your thumb, press the blue tab to release the locking mechanism.
c. Pull the power supply out of the NSM module while using your other hand to support its weight.
d. Using both hands, support and align the edges of the power supply with the opening in the replacement
NSM module.
e. Gently push the power supply into the NSM module until the locking mechanism clicks into place.
Do not use excessive force or you might damage the internal connector.
f. Rotate the cam handle to the closed position.
11. Insert the replacement NSM module into the shelf:
a. Make sure that the latching mechanism arms are locked in the fully extended position.
b. Using both hands, gently slide the NSM module into the shelf until the weight of the NSM module is
fully supported by the shelf.
c. Push the NSM module into the shelf until it stops (about half an inch from the back of the shelf).
You can place your thumbs on the orange tabs on the front of each finger loop (of the latching
mechanism arms) to push in the NSM module.
d. Loop your index fingers through the finger holes of the latching mechanisms on either side of the NSM
module.
If you are inserting the bottom NSM module, and if the bottom rail is obstructing access
to the latching mechanisms, place your index fingers through the finger holes from the
inside (by crossing your arms).
e. With your thumbs, press down and hold the orange tabs on top of the latching mechanisms.
f. Gently push forward to get the latches over the stop.
g. Release your thumbs from the tops of the latching mechanisms, and then continue pushing until the
latching mechanisms snap into place.
The NSM module should be fully inserted into the shelf and flush with the edges of the shelf.
