I/O Chassis in HP Superdome IOX Cabinets

HP System Partitions Guide: Administration for nPartitions, rev 5.1

See Figure 1-7 on page 50 for details.

Step 2. To access the PCI card slots in an HP Superdome compute cabinet’s I/O

chassis, you must remove the cover from the top of the I/O chassis.

In each Superdome compute cabinet I/O chassis—when facing the

chassis—PCI slot 0 is on the right and PCI slot 11 is on the left.

I/O Chassis in HP Superdome IOX Cabinets

Up to two I/O expansion (IOX) cabinets can reside in an HP Superdome

complex.

I/O expansion cabinets are numbered cabinets 8 and 9.

The IOX cabinet uses the same I/O chassis as the Superdome compute

cabinet. Each IOX I/O chassis has 12 slots, numbered from 11 to 0. See

Table 1-1 on page 49 for details about the card slots.

Each I/O expansion cabinet has its own power supplies, fans, and

utilities (which are connected to the Superdome server’s service

processor bus).

The I/O chassis (and PCI card slots) within each I/O expansion cabinet

are made available to nPartitions through direct I/O chassis-to-cell

connections—exactly as internal Superdome server cabinet I/O chassis

are connected to cells.

Three I/O bays can be housed in each IOX. These bays are numbered

from bottom to top: I/O bay 0, bay 1, and bay 2, as shown in Figure 1-8.
