CAUTION NOTE Installing or Replacing Parts and Accessories System Memory 5. Rotate the hard disk drive cage to the open position (see page 149). 6. Remove the chassis beam assembly (see page 152). 7. Remove the Memory Expander Card (MEC) (see page 155). 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 10-10. 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 10-11 on page 161. b. If you are replacing existing RIMMs, open the retaining clips by pushing down on them, and remove the existing RIMMs from their sockets. 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. 160 Chapter 10
