Adding or Replacing CPUs and Memories 1-11
Follow Steps 1 through 6 in Section 1.4 and then:
1. If you are adding a module, remove the filler module from the slot
where you will install the new module. Hold the filler module firmly
on the vertical piece closest to you and gently pull it out toward you.
Place it aside for return.
2. On the module to be inserted, pull out the two black restraining clips
to the right and pull the two levers out until they are perpendicular to
the front edge of the module. The clips snap open.
3. Pick up the module to be inserted, holding it securely with both hands.
4. Align the bottom tracks of the module with the tracks in the card cage
slot (see Figure 1-6). Align the top ridge of the module with the track
at the top of the card cage slot.
5. Holding the module level, gently guide it into the card cage. If you en-
counter any resistance, check the alignment of the tracks and reinsert.
As the module slides in, release your hand from the corner and guide
the module with two hands as you insert it.
When the module is fully inserted, the front of the module will be flush
with the card cage. Note that the module does not click when it is
fully inserted.
6. Holding the two metal tabs, push both of them toward the edges of
the module simultaneously. Check that the ends of the metal tabs are
fitting into the guides of the card cage slot (see Figure 1-6). Push the
levers toward the module case.
7. Snap the black restraining clips across the levers to secure the mod-
ule.
8. Check that filler modules are placed in all unused slots.
9. Replace the plate covering the card cage by tightening the two thumb-
screws.
10. Close the cabinet doors.
