Chapter 4 Maintenance Guidelines

• Ensure the front ridge on the bottom of the heatsink fits into the groove between the processor socket
and processor and both ridges should straddle the processor.
The bottom of each heatsink has two ridges, which are used to align the heatsink with the processor.
• Both latches (hook and thumb) on the heatsink must be connected to the processor socket base or the
processor will overheat.
The mechanical latches on the heatsink ensure a good thermal bond between the heatsink and the
processor through the thermal patch.
• If the processor is upgraded to a faster processor speed with a different front side bus (FSB) speed than
the previous processor, the circuitry on the system board detects the change and automatically adjusts to
the faster front side bus speed.
• The HP Server tc2100 only supports 100 MHz and 133 MHz FSB speeds.
