The NPE-300 uses an RM7000 microprocessor that operates at an internal clock speed of
–
262 MHz.
The NPE-400 uses an RM7000 microprocessor that operates at an internal clock speed of
–
350 MHz.
The NPE-300 has two system controllers that provide processor access to the midplane and
–
single I/O controller PCI buses. The system controllers also allow port adapters access to
SDRAM using any of the three PCI buses.
The NPE-400 has a single system controller that provides system access.
