2.10 I/O Carrier
The I/O carrier is the interface that connects the I/O port of the Profusion chip set to the following:
• Ten hot-swappable PCI slots (four of which support 66-MHz transactions).
• Legacy connector (video, keyboard, serial, parallel, USB, and Intelligent Chassis Man-
agement Bus (ICMB) ports).
• Dual LVDS.
• Internal IDE buses, floppy disk, disk drives, and SCSI connectors for peripheral support.
The PCI hot-plug (PHP) I/O carrier, legacy connector, LVDS connectors, ICMB board, and
enhanced PCI hot-plug board are assembled onto the I/O carrier tray. The PCI hot-plug base
shield is assembled and mounted over the PHP I/O board, and secured by six screws. The PHP
slot dividers snap onto the PHP base shield.
