Installation and Component
Replacement
This guide provides instructions for the installation or replacement of the Sun™
Enterprise™ PCI I/O board and for the replacement of parts mounted on the board.
Each PCI board has two riser cards, each accommodating one PCI card (
FIGURE 1-1
).
The PCI card voltage rating must be matched to the voltage rating of the riser card.
Consult your Sun sales representative for the PCI cards supported for your
particular system configuration.
Riser card connectors can be one of two voltage types, 5.0V or 3.3V. Sun PCI I/O
boards are shipped with two 5.0V riser cards (installed) and two 3.3V riser cards (not
installed). If you are switching to a 3.3V PCI card, you must replace the installed
5.0V riser card with the 3.3V riser card.
