Figure 3-8 RXE-100 PCI-X expansion board (6 slots)
For each of the three buses (A, B, C), one of the following can be installed:
One 64-bit 3.3 V PCI-X 133 MHz adapter (in the odd-numbered slot), running
at up to 133 MHz
Two 64-bit 3.3 V PCI-X 133 MHz adapters running at up to 100 MHz
Two 64-bit 3.3 V PCI or PCI-X, 33 or 66 MHz adapters
Note: The PCI slots supports 3.3 V adapters only. 5 V adapters are not
supported.
Like the x440, these slots can accept adapters rated at speeds ranging from 33
MHz to 133 MHz. When deciding which adapters to put in which slots, consider
the following:
Each adapter has a maximum rated speed and each bus also has a
maximum rated speed.
