this chapter.

CAUTION
Observe static precautions. Use an antistatic wrist strap.
Hold the processor only by its edges.

If your system has one processor and you are adding a second processor,
then you must remove the termination board in the secondary connector and
store it appropriately.
3. If your system has one processor and you are replacing it, leave the
terminator board intact in the empty secondary processor connector. Remove
the processor you want to replace.
4. If your system has two processors and you are replacing one or both, remove
the appropriate one(s).
5. Pull the processor latches, Item A in Figure "Removing a Processor" below,
out away from the edges of the SECC2 cartridge to free them from the
Universal Retention Module (URM).
6.
Lift the SECC2 cartridge upward, out of the URM and place it on a
grounded, static-free surface or conductive foam pad.
7. Put the old processor in a piece of conductive foam and store in an antistatic
package.
Removing a Processor

Remove the new processor from its antistatic package and place it on a

on the bottom of the SECC2 cartridge fits into the connector key in the slot.
Push down firmly, with even pressure on both sides of the top, until the
cartridge is seated making a clicking noise.
