Replacing a mezzanine network adapter
Guidelines
The blade server supports installing a maximum of three connector network adapters.
When you install a mezzanine network adapter, make sure the corresponding processor and ICM
are present. For more information about mezzanine connector and processor mapping relations, see
PCIe connectors in "Appendix A Server specifications". For more information about the mapping
relations between mezzanine network adapters and ICMs, see internal networking in "Appendix A
Server specifications".
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 replacing, back up data, stop all services, and power off the server. For more information, see
"
Powering off the blade server ."
Remove the blade server. For more information, see " Removing the blade server ."
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.
