Connectors, Switches, and LED Indicators 4-9 Processor Core Frequency (SW4) and System ID (SW6) Switches Processor Core Frequency Switches (SW4) CAUTION: The System ROM determines proper processor speeds. This section shows only the location of the switches and the default settings of each. These default settings must be set exactly as shown for proper operation of the ROM. Figure 4-7 shows the location and default settings of the processor core frequency switch (SW4). Table 4-7 lists the processor core frequency switch settings for the ProLiant DL580 server with processor speeds ranging from 700 to 900 MHz. Off 1 2 3 4 Figure 4-7.
