Figure 7-31 Backplane Location in the Card Cage
When removing the backplane from the card cage assembly, you must first
remove the DC power buss bars from the power supply.
The control board enclosure must be removed before the backplane can be
fully accessed. To remove the control board enclosure, see Figure 7-32 and
proceed as follows:
1. Remove the four hex-head screws shown on the left side of Figure 7-32.
Access to the screws is through the card cage.
2. Remove the two hex-head screws shown on the right side of Figure 7-32.
Access these screws from the front of the system.
3. Remove and set aside the control board enclosure.
Note – All cables that are plugged into or are located in front of the backplane
must be removed and pulled out of the way.
