xSeries 440 Planning and Installation Guide
Installed adapters will operate at the slowest of three speeds:
– The rated speed of adapter 1 in the bus
– The rated speed of adapter 2 in the bus
– The rated speed of the bus
32-bit adapters can be installed in any of the slots and will run in 32-bit mode.
32-bit and 64-bit adapters can coexist in 64-bit slots in the same bus. The
32-bit adapters will run in 32-bit mode, and the 64-bit adapters will run in
64-bit mode.
When installing a 133 MHz PCI-X adapter, it must be installed in the first or
odd-numbered slot in the bus (that is in slots 1, 3 or 5).
Like the x440, a PCI-X and a PCI adapter can be installed in slots on the
same bus in the RXE-100. However, these two adapters will both operate in
PCI mode.
In addition, if you have a PCI-X adapter installed, you cannot hot-add a PCI
adapter to the same bus. This is because with just the PCI-X adapter
installed, the bus is running in PCI-X mode, and you cannot hot-add a PCI
adapter into a bus that is in PCI-X mode.
With Windows NT 4.0 Enterprise Edition, certain token-ring adapters do not
work in some slots in the RXE-100. See RETAIN tip H175383 for more
information:

Connecting the RXE-100
There are two types of cables used to connect the RXE-100 to the x440:
Remote I/O cable, for data
This cable connects from the x440 RXE Expansion Port A to the RXE-100 as
shown in Figure 3-9 on page 81. Two lengths are available:
– 3.5 m Remote I/O cable kit (part number 31P6102)
– 8 m Remote I/O cable kit (part number 31P6103)
