Chapter 6 NOTE Installing an Additional Processor No speed switch settings are required for the supported processors (866, 933 MHz, or 1 GHz) in the HP Netserver. These processors rely on the internal settings within the processors and do not rely on external switch settings on the system board. Installing the Heatsink Once the processor is installed, the heatsink must be installed on top of the processor. Each processor requires a heatsink and a thermal bonding between the processor and the heatsink, provided by the thermal patch. The heatsink is mechanically connected to the processor socket with both latches, mechanically making contact with processor. 1. Remove the heatsink from the shipping container and ensure you do not touch the thermal patch on the bottom of the heatsink. CAUTION Ensure you have a good thermal patch for good contact with the processor to avoid thermal overheating. If you have not made good contact on the processor, it may shutdown to prevent overheating. The supported processors have thermal sensors inside the processor chip to prevent overheating. If the processor runs hot, it may operate intermittently or crash the system causing data loss or file corruption. This may also lead to processor damage. Refer to the indicators in Chapter 1, "Controls, Ports, and Indicators." 2. Inspect the thermal patch to ensure the thermal material covers the whole patch. ◊ If not, you must remove the old patch and replace it with a new thermal patch. The heatsink kit should contain extra thermal patches. The thermal patch is pealed off the backing and placed in the center of the heatsink in the area marked. ◊ If you are re-installing a heatsink on to the processor, you may need to scrap off any thermal material left on top of the processor chip. You can use your fingernail to scrap off the material, but ensure you are grounded with a static-dissipating wrist-strap. 51
