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.
If the server is installed with a TCM/TPM, to avoid damage to the connector, do not remove the
TCM/TPM.
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.
Before installing, make sure that you back up the data, stop all services, and power off the server.

Remove the blade server. For more information, see "
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.
You might also remove other components. For the removed components to be reinstalled correctly,
record their positions and connections before removal, for example, taking pictures of cable
connection and drive installation positions, or labeling cables.
Removing the system board
1.
Remove all front drives.
2.
Remove the access panel. Press the unlock button on the access panel, slide the panel to the

Remove the air baffle.
5.
Remove the front drive backplane.
6.
Remove all storage controllers, NVMe VROC modules, mezzanine modules, Micro SDs, and
SATA M.2 SSDs, if any.
7.
Remove all DIMMs, processors, and heatsinks.
8.
Install protective covers over empty processor sockets.
9.
Remove the system board:
a.
Loosen the two captive screws on the system board.
