2-3 Mounting the Serverboard into a Chassis
All serverboards have standard mounting holes to fi t different types of chassis.
Make sure that the locations of all the mounting holes for both the serverboard
and the chassis match. Although a chassis may have both plastic and metal
mounting fasteners, metal ones are highly recommended because they ground
the serverboard to the chassis. Make sure that the metal standoffs click in or are
screwed in tightly.
1. Check the compatibility of the serverboard ports and the I/O shield
The H8QM3-2/H8QMi-2 serverboard requires a chassis that can support extended
ATX boards of 16" x 13" in size. Make sure that the I/O ports on the serverboard
align with their respective holes in the I/O shield at the rear of the chassis.
2. Mounting the serverboard onto the mainboard tray in the chassis
Carefully mount the serverboard onto the mainboard tray by aligning the serverboard
mounting holes with the raised metal standoffs in the tray. Insert screws into all
the mounting holes in the serverboard that line up with the standoffs. Then use a
screwdriver to secure the serverboard to the mainboard tray - tighten until just snug
(if too tight you might strip the threads). Metal screws provide an electrical contact
to the serverboard ground to provide a continuous ground for the system.
2-4 Installing Memory
CAUTION
Exercise extreme care when installing or removing memory modules
to prevent any possible damage.
1. Insert each memory module vertically into its slot, paying attention to the notch
along the bottom of the module to prevent inserting the module incorrectly (see
Figure 2-2). Insert fi rst into the 1A slot(s), then the 1B slot(s), etc. See support
information below.
2. Gently press down on the memory module until it snaps into place.
Note: Each processor has its own built-in memory controller, consequently each
CPU has an eight-slot memory bank associated with it. (Memory installed into a
bank with no CPU present cannot be accessed.) 256 MB, 512 MB, 1 GB, 2 GB and
4 GB memory modules are supported. It is highly recommended that you remove
the power cord from the system before installing or changing DIMMs.
