Replacing a system DIMM involves identifying the target DIMM through the associated
error message, locating the target DIMM using the FRU map on the air duct or the lit LED
on the motherboard, and then replacing the DIMM.
1. Rotate the air duct to the open position.
2. Locate the DIMMs on your controller module.
