removing the processor/memory board, let th e
components cool for 10 minutes before continuing with
the procedures described here.
1. Power off the system and remove the side panel as
described earlier in this chapter.
Notice: Observe static precautions. Use an antistatic
wrist strap.
2. Remove the board support panel described earlier in
this chapter, see Removing the Board Support Panel.
3. Holding the board by its edges, carefully pull it out
until the edge connectors are free (see Figure

4. Store board in an antistatic protective wrapp er if
you are not installing or removing a processor or
