Full Glossary on page 287 .

NOTE I/O expansion cabinets are not available with early shipments of

Superdome. Contact your HP Sales Representative for up-to-date

information.

An I/O expansion cabinet contains up to six twelve-slot I/O chassis

(cardcages). Unlike a CPU cabinet, it contains no slots for cells.

You need an I/O expansion cabinet if:

• you need more than 48 I/O slots per CPU cabinet; or

• you need to attach I/O to more than four cells in a CPU cabinet.

For more information see:

• “Cell I/O” on page 308.

• “Partitions, Cells and I/O Chassis” on page 333.
