Chapter 2 System Setup 17
2.4 Installing Memory (DRAM)
The PPC-57 provides one 72-pin SIMM (single in-line memory
module) socket for installation of a single DRAM module (with
1 MB, 4 MB, or 16 MB DRAM). To install DRAM modules,
follow these steps:
1. Verify that all power sources to the PPC-57 have been discon-
nected.
2. Before installing DRAM, the rear panel must be opened. (See
Section 2.3.)
3. Slip the memory module into the socket at a 45 degree angle.
Note: The module can only fit into the SIMM socket one
way. Its chips must face the CHIPSET on the
PCM-3866 (all-in-one board), and its golden pins
must point down into the SIMM socket.
4. Push the module toward the vertical posts at both ends of the
socket until the module is upright and the retaining clips at
both ends of the socket click into place. When positioned
correctly, the pins on top of the vertical posts should corre-
spond to the circular holes on the ends of the module.
