Chapter 7 Installing Additional Processors CAUTION Do not attempt to install or remove PCI boards with the HP NetServer in any kind of sleep state, or a system crash or hang may occur. 2. If required, extend the HP NetServer out from the rack on its slides by performing the necessary steps, including the safety precautions. Refer to Chapter 3, "Opening and Closing the HP NetServer." 3. Access the Processor Baseboard by removing the chassis top cover. Refer to Chapter 3, "Opening and Closing the HP NetServer." 4. Check the jumper settings on the processor baseboard. See Figures 7-4 and 7-5. When reconfiguring the HP NetServer with processors of a different clock speed than previously used, you must change the jumper settings on jumper block J6A1 on the processor baseboard. See Figures 7-4 and 7-5. 5. If necessary, change the jumper settings to match the processor speed of all the processor modules in the HP NetServer. CAUTION All processors on the baseboard must have the same speed, cache size and product number. For example, you can't mix three 550 MHz processors with different cache sizes, or you can't mix 550 MHz with 500 MHz processors. The processor modules must all operate at the same speed, cache size, and with the same product number. For processor speeds other than those shown in Figure 7-5, refer to the expansion kit and Figure 7-4 for the jumper positions of the processor module's speed on jumper block J6A1. 81
