Upgrading

Chapter 9

You cannot easily install a SIMM in the MM2 socket while the

MM1 socket is occupied. So either install the MM2 SIMM first,

or temporarily remove the MM1 SIMM if it is still required in

the new configuration.

Installing and removing SIMMs

To locate the SIMM sockets:

1. Turn off the computer and unplug all power cords.

2. Take suitable anti-static precautions and remove the

system unit cover.

If you are unfamiliar with anti-static precautions or

the procedure for removing the system unit cover,

see Appendix A, “Inside the System Unit”.

3. Use the illustration at the start of this chapter to

locate the SIMM sockets.

4. Compare the current configuration of SIMMs with the

recommended configuration for the memory upgrade

you intend to install.

If necessary, remove one or both existing SIMMs,

before going on to install the new SIMM(s).

To remove a SIMM:

1. Disengage the metal holding clips on each side of the

socket using your forefingers. Place your thumbs on

the top edge of the SIMM and tilt the SIMM to about

to the vertical.

2. Lift the SIMM out of its socket. Hold the SIMM by its

edges and avoid touching the metal contacts.
