Memory Installation

The MPC8XXFADS is supplied with two types of memory SIMM:

•

Dynamic Memory SIMM

•

Flash Memory SIMM.

To avoid shipment damage, these memories are packed aside rather than being installed in their

sockets. Therefore, they should be installed on site. To install a memory SIMM, it should be taken out

of its package, put diagonally in its socket (no error can be made here, since the Flash socket has 80

contacts, while the DRAM socket has 72) and then twisted to a vertical position until the metal lock

clips are locked. See FIGURE 2-11 "Memory SIMM Installation" below.

CAUTION

The memory SIMMs have alignment nibble near

their # 1 pin. It is important to align the memory cor-

rectly before it is twisted, otherwise damage might

be inflicted to both the memory SIMM and its sock-

et.
