To remove the cache memory card, follow these steps:
1. Unlatch and rotate the power supply up until it locks (see Figure 6-14).
2. Rock the cache memory card from side to side while pulling up on it.
Take note of which end of the cache memory card is the pin-1 end (nearest
the right side of the system board).
When you replace the cache memory card, be sure that the pin-1 end of the
cache memory card (which has a 1 etched near the connector) is toward the
right side of the system board.
