Installing IOMs and MDAs
7450 ESS-7 Page 101
To install an IOM:
Step 1 Remove the IOM from the packaging. Do not touch the printed circuit board and
connector pins.
Step 2 Holding the IOM by the edges, rotate the ejector levers inward. The ejector levers must
be in this position to release the locking mechanism.
Step 3 Align the IOM with the slot guides and slide inward until the locking mechanism
engages with the card cage.
Step 4 Rotate the ejector levers outward to lock the IOM in place.
If an IOM lever does not shift to the locked position, then the card is probably not properly
seated. Pull the IOM out halfway, verify the card is moving properly in the slot guides and
then reinsert it. Shift the levers to the locked position.
Step 5 Secure into place by tightening the captive screws.
