Processor Board Before removing the processor board, perform the following steps: S Remove the optional external graphics processor (if installed). S Remove the floor stand. S Open the system unit. S Remove the EISA assembly or optional graphics (CRX or HCRX) board, if present. S Disconnect all internal and external cables. When installing the processor board, use a wide, flat object, such as a wooden ruler or flat-tipped screwdriver, between the front wall of the system unit and the edge of the processor board to lever the board toward the rear of the system (see Figure 5-45). This will enable you to align the screw hole and seat the connectors at the rear of the system unit. Swap the memory boards to the new/exchange processor board, as shown in the "Memory" section. If you are replacing a 715/C, 715/33, 715/50, or 715/75 processor board with another 715/C, 715/33, 715/50, or 715/75 processor board, remove the EEPROM from the failed processor board and install it in the new/exchange processor board, as shown in the "System EEPROM" section.

Processor Board
Before removing the processor board, perform the following steps:
S
Remove the optional external graphics processor (if installed).
S
Remove the floor stand.
S
Open the system unit.
S
Remove the EISA assembly or optional graphics (CRX or HCRX) board, if
present.
S
Disconnect all internal and external cables.
When installing the processor board, use a wide, flat object, such as a wooden ruler
or flat–tipped screwdriver, between the front wall of the system unit and the edge of
the processor board to lever the board toward the rear of the system (see
Figure 5–45). This will enable you to align the screw hole and seat the connectors at
the rear of the system unit.
Swap the memory boards to the new/exchange processor board, as shown in the
“Memory” section.
If you are replacing a 715/C, 715/33, 715/50, or 715/75 processor board with another
715/C, 715/33, 715/50, or 715/75 processor board, remove the EEPROM from the
failed processor board and install it in the new/exchange processor board, as shown
in the “System EEPROM” section.
