Remove a Memory Riser

This is a cold-service procedure that can be performed by a customer. Power down the server

completely before performing this procedure.

Caution - This procedure requires that you handle components that are sensitive to ESD which

can cause server components to fail.

Note - Your server could include a memory riser that is secured with a flat-head screw. If that is

the case, use a No. 1 flat-blade screwdriver to service that memory riser.

Prepare for servicing.

See “Preparing for Service” on page 45.

Identify the memory riser with the faulty DIMM by pressing the Remind button on

the air divider as shown in the following figure.
