1. Disconnect the switch’s power cord, if attached.
2. Unscrew the three Phillips flathead screws on the switch’s blank
faceplate and save for future use. Keep the blank panel attached if 
the MDA slot is empty.
Caution
Do not remove the MDA blank faceplates if you are not installing 
MDAs.
3. Unpack the MDA making sure to observe ESD precautions.
The standoff on the MDA guides it correctly into position so 
that the MDA’s 50-pin plug aligns with the 50-pin receptacle 
on the main board. Refer to Figure 2-3 for the location of the 
standoff and the 50-pin connector.
