down, as shown in Figure 2-5 on page 2-10. Then locate the two posts and the sockets, also 
shown in Figure 2-5.

panel opening.
9. Insert the IOM into the sockets as follows:
a. Firmly push the IOM toward the front panel opening to compress the sealing gasket.
a. Carefully line up the holes in the back of the IOM with the two posts. Let the IOM rest on 
the posts.
