System Features
Bus Architecture
Four PCI-X slots are available. The slots numbered 1 through 4 and are 64-bit capable
at 133 MHz, 3.3 volts. Use slots 3 and 4 with PCI adapters that demand high
performance. Use slots 1 and 2 with PCI adapters that do not demand high
performance. All PCI-X slots are capable of running either 64-bit or 32-bit adapters.
However, a 32-bit adapter operates in a 32-bit mode and shows no performance
advantage while running in a 64-bit slot. The following illustration indicates the PCI-X
slot numbered locations when viewing from the rear of the system.
