Chapter 1 PCI Card OL* Overview and Concepts

Most cards and servers support OL* functionality, but there are a few that do not, see specific card and server documentation for details.

	WARNING! Observe all safety precautions to avoid being injured while accessing systems to add or replace cards.

	CAUTION: Observe all safety precautions prior to physically accessing the system to prevent static discharge from damaging the system.

	NOTE: Certain “Classes” of hardware are not intended for access by users. At this time this includes V-Class and Superdome systems. HP recommends that these systems only be opened by a qualified HP Engineer. Failure to observe this requirement can invalidate any support agreement or warranty to which the owner might otherwise be entitled.

The three methods of performing OL* operations are discussed in separate chapters.

These three tools all can perform similar tasks, but with different techniques. A direct comparison of the methods can help you decide which method to use in a particular situation and is presented in “Comparing OL* Methods”.

It is preferable to complete the operation using the same method, but one can start with one and finish with another. A table that shows the consequences of mixing methods in “Mixing OL* Methods”.

With many cards close together, it can be difficult to locate a particular slot. You can turn the Attention LED to a BLINKing state for easy location of the desired slot. Information for BLINKing the Attention Button is included with each method.
