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 x450, 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. Connecting the RXE-100 There are two types of cables used to connect the RXE-100 to the x450: Remote I/O cable, for data. Two lengths are available: - 3.5 m Remote I/O cable kit (part number 31P6102), like the one shipped with the RXE-100 - 8 m Remote I/O cable kit (part number 31P6103) Interconnect management cable, for remote I/O management. This is a standard Ethernet cable. The RXE-100 ships with a 3.5 m cable. Two lengths are available: - 3.5 m interconnect management cable kit (part number 31P6087) - 8 m interconnect management cable kit (part number 31P6088) Use the 8 m versions of each of these cables if the distances between the two devices warrant the extra length (for example, in separate racks). When the RXE-100 has only six PCI-X slots installed, connect a single Remote I/O cable and a single management cable, as shown in Figure 3-7 on page 54. Important: Power to the RXE-100 is controlled by the x450 via the interconnect management cable and under the control of the Remote Supervisor Adapter. Chapter 3. Planning 53

Connecting the RXE-100
There are two types of cables used to connect the RXE-100 to the x450:
±
Remote I/O cable, for data. Two lengths are available:
–
3.5 m Remote I/O cable kit (part number 31P6102), like the one shipped
with the RXE-100
–
8 m Remote I/O cable kit (part number 31P6103)
±
Interconnect management cable, for remote I/O management. This is a
standard Ethernet cable. The RXE-100 ships with a 3.5 m cable.
Two lengths are available:
–
3.5 m interconnect management cable kit (part number 31P6087)
–
8 m interconnect management cable kit (part number 31P6088)
Use the 8 m versions of each of these cables if the distances between the two
devices warrant the extra length (for example, in separate racks).
When the RXE-100 has only six PCI-X slots installed, connect a single
Remote I/O cable and a single management cable, as shown in Figure 3-7 on
page 54.
Important:
Power to the RXE-100 is controlled by the x450 via the
interconnect management cable and under the control of the Remote
Supervisor Adapter.
