5-3 Processor and Heatsink Installation
Installing the Processor (install to the CPU#1 socket fi rst)
1. Lift the lever on CPU socket #1 until
it points straight up.
Exercise extreme caution when handling and installing the proces-
sor. Always connect the power cord last and always remove it be-
fore adding, removing or changing any hardware components.
5-2 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 H8DA8 serverboard requires a chassis that can support extended ATX boards
of 12" x 13.05" in size, such as the SC813S-500C. 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.
