5. Rotate the hard disk drive cage to the open position (see page 19).
6. Remove the chassis beam assembly (see page 22).
7. Remove the Memory Expander Card (MEC) (see page 25).
CAUTION You must remove the MEC to install RIMMs (and CRIMMs). The
MEC card guides are not strong enough to bear the force of the
RIMMs being inserted.
8. Install the RIMMs (and CRIMMs if required) on the MEC according
to Figure 2-10.
a. If you are installing additional RIMMs, you may need to remove
the CRIMMs. Open the retaining clips by pushing down on them,
and remove the CRIMM from the socket. See Figure 2-11 on
page 31.
b. If you are replacing existing RIMMs, open the retaining clips by
pushing down on them, and remove the existing RIMMs from
their sockets.
NOTE Always store any removed RIMMs and CRIMMs in a safe place for
future use. CRIMMs may be stored in an empty memory bank if one
is available.
c. Install your new RIMMs or CRIMMs, ensuring that the two
notches on the bottom edge are aligned with those of the socket.
With the two retaining clips open, press the RIMM fully into the
socket until the retaining clips click into position. You can also
close the retaining clips by hand to ensure that the RIMM is
correctly inserted.
