Installing Hardware Options Upgrading a Processor CAUTION: To be sure that the system ROM recognizes the new processor you are installing, update the ROM if necessary. For the most recent ROMpaq, refer to the HP website: www.hp.com/servers/proliant/manage Failure to flash your ROM before installing processors can cause system failure. CAUTION: Processor socket 1 and PPM slot 1 must always be populated. Failure to populate processor socket 1 and PPM slot 1 prevents the system from operating. IMPORTANT: Install a PPM for each processor in the system. When installing a new processor, you must also install a new PPM. IMPORTANT: If processors of differing speeds are installed, each processor matches the rated speed of the slower processor. For optimal performance, upgrade both processors at the same time, rather than mixing processor speeds. IMPORTANT: ProLiant ML530 Generation 2 servers ship with gold-colored processor/heatsink assemblies. To be sure that you install a processor compatible with your server, only install processors with gold-colored heatsinks. NOTE: When upgrading the processors to a higher speed, you do not need to set any switches to set processor frequency. The system ROM automatically sets the processor frequency during POST. To replace existing processors with new processors of higher frequency: 1. For tower-model servers only, open the front bezel door. See "Opening the Front Bezel Door" in this chapter. 2. Power down the server. See "Powering Down the Server" in this chapter. 3. For rack-model servers only, extend the server from the rack by loosening the front panel thumbscrews and extending the server out of the front of the rack until it stops. 4. Remove the access panel. See "Removing the Access Panel" in this chapter. 3-22 HP ProLiant ML530 Generation 2 Server Setup and Installation Guide
