5 Remove the SIMM(s). On the NT6D66AA card, remove SIMM T6 first:
• Using the non-conductive screw driver provided, carefully move
each latch away first from one end of the SIMM, and then the other
end. The SIMM will pivot away from the others until it is at
approximately a 50- to 70-degree angle to the board (see Figure 12-4
on page 12-19 and Figure 12-5 on page 12-20).
Note: If, using the non-conductive screw driver, the SIMM does not
release from the latches, use your thumbnails, one on each latch, to
release the latches: for plastic latches, the latches are located on the ends
of each SIMM; for metal latches, the levers protrude from each latch.
Carefully move the latches outward simultaneously until the SIMM
pivots away from the others and it is at approximately a 50- to 70-degree
angle to the board.
• Gently pull the SIMM out of the socket.
6 Install the two new SIMMs. On the NT6D66AA card, install SIMM T5
first; on the NT6D66BA card, install SIMM T3 first:
• Orient the new SIMM so that the notch at one end of the SIMM
aligns with the key at one end of the SIMM socket (see Figure 12-2
on page 12-17 and Figure 12-3 on page 12-18).
• Hold the SIMM at approximately a 50- to 70-degree angle and
gently insert the SIMM into the socket (see Figure 12-4 on
page 12-19 and Figure 12-5 on page 12-20).
Do not force the SIMM into the socket. Any damage caused to the
socket will require replacement of the NT6D66 CP card.
• Using your thumbs and index fingers only (at the upper corners of
the SIMM), carefully lean the SIMM toward the others until it is
upright and the latch at each end of the SIMM snaps into place. If
necessary, use the non-conductive screw driver to assist you in
opening each latch while you move the SIMM into the upright
position.
