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 H8DCR-3 serverboard requires a chassis that can support extended ATX boards of 12" x 13.05" in size, such as the SC813TQ+-500. 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 serverboard tray in the chassis

Carefully mount the serverboard onto the serverboard 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 serverboard 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.

5-3 Processor and Heatsink Installation

!

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.

CPU Backplates

Two CPU backplates (BKT-0004) have been preinstalled to the underside of the serverboard. These backplates prevent the CPU area of the serverboard from bending and provide a base for attaching the CPU heatsinks.
