Installing or Replacing Server Components
DIMM Replacement Procedure
To install a DIMM assembly, follow these steps:
Step 1 Remove the DIMM that you are replacing:
a.Power off the server as described in the “Shutting Down and Powering Off the Server” section on page
b.Slide the server out the front of the rack far enough so that you can remove the top cover. You might have to detach cables from the rear panel to provide clearance.
Caution If you cannot safely view and access the component, remove the server from the rack.
c.Remove the top cover as described in “Removing and Replacing the Server Top Cover” section on page
d.Remove the internal air baffle from the server to provide access to the DIMM slots.
e.Open the ejector levers at both ends of the DIMM slot, then lift the DIMM out of the slot.
Step 2 Install a new DIMM:
Note Before installing DIMMs, refer to the population guidelines. See Memory Performance Guidelines and Population Rules, page
f.Align the new DIMM with the empty slot on the motherboard. Use the alignment key in the DIMM slot to correctly orient the DIMM.
g.Push down evenly on the top corners of the DIMM until it is fully seated and the ejector levers on both ends lock into place.
h.Replace the air baffle and the top cover.
i.Replace the server in the rack, replace cables, and then power on the server by pressing the Power button.
