GBIC

Each SBus+ and Graphics+ I/O board provides mounting for two GBIC interfaces. A GBIC (Gigabit Interface Converter) is a hot-pluggable unit that converts any of the standard Fibre Channel connectors and signaling technologies. The GBIC Fibre Channel referred to in this manual is 100 Mbytes/second.

The SBus+ I/O board with 100 MB/sec Fibre Channel includes two SYSIO ASICs that provide two SBuses:

• One for two plug-in SBus cards and two GBIC interfaces

• One for one plug-in SBus card and the onboard devices (10/100 Mbit TPE and Single-ended Fast/Wide SCSI).

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 MB/sec Fibre Channel includes one SYSIO ASIC that provides a single SBus for two plug-in SBus cards, two GBIC 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.
