6. You must set jumpers including the those for the CPU, clock (J15,
J4), frequency ratio (J8), voltage (J14), and P54C/P55C selection
setting (J10).
7. To remove a CPU, pull the lever out to the side a little and raise it as
far as it will go. Lift out the CPU chip.
NOTE! When you install a new CPU, be sure to adjust the
board jumper settings. Improper settings may damage
the CPU. (See Chapter 3 for jumper settings.)
2.3.3 Installing DRAM (SIMMs)
You can install from 8 MB to 128 MB of DRAM memory. The
PCM-5865 CPU card provides two 72-pin SIMM (Single Inline Memory
Module) sockets and supports either Fast Page Mode (FPM) or Extended
Data Output (EDO) DRAM with a speed of 70 ns or greater.
Note:
The module can only fit into a socket one way. Pin 1 of the SIMM
module must line up with the small arrowhead printed on the PCM-5865
next to the SIMM socket. The golden pins of the module must point down
into the SIMM socket.
1. Ensure that all power sources are disconnected.
2. Slip the memory module into the socket at a 45 degree angle.
3. 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
module click into place. When positioned correctly, the pins on top of
the vertical posts should correspond to the circular holes on the ends
of the module.
4. Repeat steps 2 and 3 for each module you install.
