Refer to “I/O Unit Replacement” on page 8-1 for replacement procedures.
C.5 Power
Power is provided to both midrange servers by power supply units. The redundant
power supplies allow continued system operation if a power supply fails.
TABLE C-5
lists the power supply features and specifications.
TABLE C-4 PCI-Express (PCIe) and PCI-eXtended (PCI-X) Features
PCI-Express (PCIe) Features PCI eXtended (PCI-X) Features
• High-speed serial, point-to-point
interconnect.
• Expands and doubles the data transfer
rates compared with the original PCI.
• Faster version of the parallel bus PCI
standard.
• PCI-X bus has improved protocols and a
faster clock rate compared with the parallel
bus PCI standard.
