Chapter 1 Install the Shelf and Backplane Cable
NTP-A11 Install the Rear Cover
Step 1 Locate the three screws that run vertically along both edges of the backplane (Figure 1-24).
Figure 1-24 Backplane Attachment for the Rear Cover
Tip Only six screws (three on each side) line up with the screw slots on the mounting brackets,
making the screws easy to locate.
Step 2 Loosen the top and bottom screws on one edge of the backplane to provide room to slide the mounting
brackets into place using the u-shaped screw slots on each end.
Step 3 Slide one of the mounting brackets into place and tighten the screws.
Step 4 Repeat Steps 2 and 3 for the second mounting bracket.
Step 5 Attach the cover by hanging it from the mounting screws on the back of the mounting brackets and
pulling it down until it fits snugly into place.
