Verifying the replacement
Use one of the following methods to verify that the DIMM is installed correctly:
•
Using the operating system:
In Windows, select
Run
in the
Start
menu, enter
msinfo32
, and verify the memory capacity
of the DIMM.
In Linux, execute the
cat /proc/meminfo
command to verify the memory capacity.
•
Using HDM:
Log in to HDM and verify the memory capacity of the DIMM. For more information, see the HDM
online help.
•
Using BIOS:
Access the BIOS, select
Socket Configuration
>
Memory Configuration
>
Memory
Topology
, and press
Enter
. Then, verify the memory capacity of the DIMM.
If the memory capacity displayed is inconsistent with the actual capacity, remove and then reinstall
the DIMM, or replace the DIMM with a new DIMM.
If the DIMM is in Mirror mode, it is normal that the displayed capacity is smaller than the actual
capacity.
Replacing the system board
Guidelines
WARNING!
To avoid bodily injury from hot surfaces, allow the server and its internal modules to cool before
touching them.
To prevent electrostatic discharge, place the removed parts on an antistatic surface or in antistatic
bags.
Prerequisites
Take the following ESD prevention measures:
•
Wear antistatic clothing.
•
Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
•
Do not wear any conductive objects, such as jewelry or watches.
When you replace a component, examine the slot and connector for damages. Make sure the pins
are not damaged (bent for example) and do not contain any foreign objects.
