Removal and Replacement

This section contains information on removals and replacements, as well as locations.

ŸThe arrows in the removals and replacements show the direction of movement to remove a field

replaceable unit		(FRU), or	to turn		a screw to	release
the	FRU. The arrows are marked			in	numeric order	to
show	the correct	sequence	of	removal.

ŸWhen other FRUs must be removed before the failing FRU is removed, they are listed at the top of the page. Go to the removal procedure for each FRU

listed, remove the FRU, and then continue with the removal of the failing FRU.

Ÿ To	replace	a	FRU, reverse the removal procedure
and	follow	any	notes that	pertain to replacement.
See	“Locations”		on page 49 for internal cable
connections		and	arrangement	information.

In addition to the safety notices below, refer to the Hardware Maintenance Manual for the computer you are servicing.
