on expansion cards, to be installed in

 

the expansion bay. To access the

 

expansion bay, you will need to

 

remove the upper front panel. Use

 

the latch to release the digital

 

operator (the panel filler plate may

 

remain). Remove the two retention

 

screws the bottom corners of the

 

upper front panel. Lift up at the

 

bottom, then disengage the two

The expansion bay has two sites for adding expansion cards. Each card connects via the interface connector, and mounts using three standoff screw locations. Further details on accessories are in Chapter 5. You may also refer to the instruction manual that comes with each type of expansion card.
