3.3 Hardware Configuration
c. Perform the following steps to attach the heat sink fan assembly:
1) Place the fan assembly on top of the heat sink, aligning the fan
mounting holes with the corresponding threaded heat sink holes.
Align the fan so that the fan power/sensor wires exit the fan closest
to connector J14 (see Figure 2–3). Fan airflow must be directed
into the heat sink (fan label facing down toward the heat sink).
2) Place the fan guard on top of the fan. Orient the guard so that the
corner mounting areas lay flush against the heat sink.
3) Secure the fan and fan guard to the heat sink with four
6–32 0.875-in screws.
4) Plug the fan power/sensor cable into connector J14 (see
Figure 2–3).
4. Install the two L2 cache SRAM SIMMs into sockets J12 and J13. Refer to
Table 2–3 for socket locations.
5. Install either four or eight system memory DRAM SIMMs. Refer to
Section 1.2.1 for configuration information and Table 2–3 for socket
locations.
a. Observe antistatic precautions. Handle SIMMs at the edges only to
prevent damage.
b. SIMMs must be installed in groups of four consisting of identical
devices.
c. Hold the SIMM at an angle with the notch facing the key in the socket.
d. Firmly push the module into the connector and stand the module
upright.
e. Make sure that the SIMM snaps into the metal locking clips on both
ends.
6. If you intend to mount the motherboard in a system enclosure, do so now.
Install the power supply into the enclosure first, then the motherboard.
Appendix A lists a suggested enclosure and a suggested power supply.
The enclosure you use should be able to accept a standard baby-AT-size
motherboard.
7. Connect the power supply to the motherboard, as shown in Figure 3–2,
with standard power to J29 and J31 and with 3.3-V dc power to J27 and
J28.
