DIMM Replacement Procedure
Step 1
Shut down and remove power from the entire system, as described in Shutting Down and Powering Off
the System, page 3-9 .
Step 2
Remove a server node from the system:
a.
Grasp the two ejector levers and pinch their latches to release the levers (see Figure 3-15 ).
b. Rotate both levers to the outside at the same time to evenly disengage the server node from its
midplane connectors.
c.
Pull the server node straight out from the system.
Step 3 Remove the server node cover as described in Removing the Server Node Cover, page 3-12 .
Step 4
Locate the faulty DIMM and remove it from the socket on the riser by opening the ejector levers at both
ends of the DIMM socket.
Step 5
Install a new DIMM:
Note Before installing DIMMs, refer to the population guidelines. See DIMM Performance
Guidelines and Population Rules, page 3-29 .
a. Align the new DIMM with the socket on the riser. Use the alignment key in the DIMM socket to
correctly orient the DIMM.
b.
Push the DIMM into the socket until it is fully seated and the ejector levers on either side of the
socket lock into place.
Step 6 Replace the server node cover as described in Removing the Server Node Cover, page 3-12 .
Step 7
Install a server node:
a. With the two ejector levers open, align the new server node with the empty bay.
Note The server node must be in the top bay, as shown in Figure 1-2 on page 1-2 .
b. Push the server node into the bay until it engages with the midplane connectors and is flush with the
chassis.
c.
Rotate both ejector levers toward the center until they lay flat and their latches lock into the rear of
the server node.
Step 8 Replace power cords and then power on the system by pressing and holding the power button on the front
handle for four seconds.
