Attention: 
•  Read “Installation Guidelines” on page 185 to ensure that you work safely.
•  Power off the server and disconnect all power cords for this task.
•  Prevent exposure to static electricity, which might lead to system halt and loss of data, by keeping static- 
sensitive components in their static-protective packages until installation, and handling these devices with 
an electrostatic-discharge wrist strap or other grounding system.

the outside of the server. Then, take the new backplane out of the package and place it on a static- 
protective surface.
Step 2.  Connect cables to the backplane. See Chapter 3 “Internal cable routing” on page 71.
Step 3.  Install the rear drive backplane. 
Figure 261. Installing the 4 x 2.5-inch rear drive backplane
a.  Align the bottom of the backplane with the studs at the bottom of the drive cage. 
b.  Lower the backplane into the drive cage so that the holes in the backplane pass through the 
pins on the drive cage, and press the backplane into position. The release latches will secure 
the backplane in place.
