Step 4: Replace the mezzanine card
The mezzanine card is located under riser number 3 (slots 4 and 5). You must remove
that riser to access the mezzanine card, replace the mezzanine card, and then reinstall
riser number 3. See the FRU map on the controller module for more information.
You can use the following animation, illustration, or the written steps to replace the mezzanine card.
