PCI+ I/O Board
FIGURE 4-5
The SBus+ I/O board with 100 MByte/second Fibre Channel includes two SYSIO
ASICs that provide two SBuses:
One for two plug-in SBus cards and two GBIC (100 MByte/second Fibre Channel)
interfaces
One for one plug-in SBus card and the onboard devices (10/100 Mbit TPE and
single-ended Fast/Wide SCSI).
Note – SBus connector slots 1 and 2 on the SBus+ I/O board can accommodate a
double-wide SBus card.
The Graphics+ I/O board with 100 MByte/second Fibre Channel includes one
SYSIO ASIC that provides a single SBus for two plug-in SBus cards, two GBIC (100
MByte/second Fibre Channel) interfaces, and the onboard devices (10/100 Mbit TPE
and Single-ended Fast/Wide SCSI).
The PCI+ I/O board has two PCI bus connectors:
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.
