4. If you replace the microprocessor in your server with a microprocessor that
operates at a different speed, be sure to set the microprocessor core-frequency-
selection jumpers correctly. See Table 5 on page 84.
5. Your server comes standard with one microprocessor installed. The
microprocessor is installed in microprocessor connector J2 and is the startup
(boot) processor. A microprocessor installed in microprocessor connector J3 is
processor 2; a microprocessor installed in microprocessor connector J4 is
processor 3; a microprocessor installed in microprocessor connector J5 is
processor 4. If more than one microprocessor is installed, the highest numbered
processor is the one the server will start from. The lower numbered
microprocessors are used as application processors.
6. Table 6 and the label on the inside cover of the server show the order in which
additional microprocessors and voltage regulator modules (VRMs) must be
installed.
Note: "T" indicates an installed terminator card; "X" indicates an installed
microprocessor or VRM. A terminator card must be installed in each microprocessor
connector that does not contain a microprocessor.
