B.6.3 PCI+ I/O Board
The PCI+ I/O board (
Each connector can accommodate a PCI riser card
Each riser card accommodates one PCI short card
In addition, onboard devices on the PCI+ I/O board provide Fast Ethernet (10/100
Mbit) and Fast/Wide SCSI interfacing.

The board contains five subsystems: I/O (PCI Bus), Memory, Bus Interface, FireHose
Interface, and Clock Generation. Four of these subsystems: the I/O (PCI Bus),
Memory, Bus Interface and internal board interface subsystems include ASICs. The
Clock subsystem distributes and generate clocks for the ASICs and PCI Bus
Interfaces on the board
