2.3 Installing passive backplane & CPU card  
The ACP-4320BP accepts an up to 15-slot backplane. To install a back-
plane and a CPU card, proceed as follows:
2.3.1 Installing the backplane
1. Remove the two screws, which mount the hold-down clamp to the 
ACP-4320BP chassis, then take out the hold-down clamp. 
2. Find the yellow label (shown as Table 2.1) on the upperplate of the 
ACP-4320BP chassis. This label instructs where to screw the copper 
stubs on the upperplate, based on the to-be-installed backplane and 
motherboard. Get the copper stubs from the accessory box of the 
ACP-4320BP packing, and follow the table to screw the copper stubs 
on the proper locations on the upperplate.

3. Refer to Figure 2.3, carefully place the backplane and the EMI spring 
plate into the ACP-4320BP chassis. For the bare ACP-4320BP chas-
sis, the EMI spring plate is stored in the accessory box.
4. Fix the backplane with screws.
