Installing the Backplane

Installing the Backplane into the Chassis (Figure 6-9)

1.  Ensure that all of the hard drive carriers have been removed from the bays in 

the front of the chassis and that the spring bar has been loosened as directed 

in the previous section. 

2.  Secure the side mounting bracket to the backplane with the two screws 

provided.

3.  Slide the backplane into the chassis at a slight angle, pushing it up against 

the side of the chassis.

4.  Ease the backplane forward, against the front of the chassis. This will aid in 

the alignment of the mounting holes.

5.  Align the mounting holes in the backplane with the holes in the chassis. 

Replace the four screws at the top of the backplane and the screw on the 

side of the chassis.

6.  Adjust the spring bar, then tighten the spring bar screws in the fl oor of the 

chassis.

7.  Reconnect all cables and return the hard drive carriers to their bays in the 

front of the chassis.

8.  Replace the chassis cover and power-up the system.
