2-3 Mounting the Serverboard into a Chassis

All serverboards and motherboards 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 H8DSR-8/H8DSR-i serverboard requires a chassis that can support extended

ATX boards 12" x 13.05" 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). See support information below.

2. Gently press down on the memory module until it snaps into place.

Notes: each processor has its own built-in memory controller, so CPU2 DIMMs

cannot be addressed if only a single CPU is installed. 128 MB, 256 MB, 512 MB,

1 GB, 2 GB* and 4 GB* memory modules are supported.

*With Opteron 246 C-stepping CPUs and above.

It is highly recommended that you remove the power cord from the system before

installing or changing any memory modules.
