How to get Opmanager to pull Hardware details (ram, cpu) and "Service-Tag" from Dell servers.

How to get Opmanager to pull Hardware details (ram, cpu) and "Service-Tag" from Dell servers.

Hi, 
Is there a way to get opmanager to find more specific hardware details about servers?(memory, cpu) Such as Service-Tag would also be great to have Opmanager pulling. Even Spiceworks does these things, and that is a freeware...

Cheers!
