Installing the External Cache Chips
Follow these steps to install the external cache chips:
1. Locate the external cache memory sockets on the main system
board, shown on page 4-5.
2.
If there is an option card in your way, remove it. See
page 4-19 for instructions.
Caution
To avoid generating static electricity and damaging the
cache chips, ground yourself by touching the metal
surface on the inside of the computer’s back panel. Then
remain as stationary as possible while you install them.
3. Remove the cache chips from their package and inspect
them. The pins should point inward at slightly less than a
90° angle.
If any of the pins are bent or crooked, straighten them gently
with your fingers or with small tweezers to align them with
the other pins. Be careful when you do this; the pins are
fragile and can break off easily.
