To install an MDA:
Step 1
Remove the MDA from the packaging and place on a flat anti-static work surface. Avoid
touching board components and connector pins.
Step 2
If an MDA slot cover is installed in the slot, loosen the cover’s captive screws and remove
cover.
Step 3
Insert the MDA into MDA slot 1 (left) or 2 (right). Align the MDA with the slot guides
and the captive screw with the threaded receptacle (see Key 2 in
Figure 19 ).
Step 4
Tighten the captive screws to secure the MDA. Do not over-tighten. The maximum
recommended torque is 10 lbf.in.
Step 5
Check the Power LED.
Step 6
Attach cables to the MDA ports.
Each MDA has a Power and Status LED. For a description of the LEDs for each MDA model,
refer to
