PCI-SB StarFabric PCI Interface Card Installation Guide 2-7
PCI-SB Card in Detail
PCI-SB Card Components
PCI-SB card components include:
SG2010 PCI-to-StarFabric bridge chipset
Two 2.5 Gbps StarFabric serial links with four RJ-45 jacks
DIP switches to set operation and test modes
Status LEDs to indicate port status
Status Light to indicate card power-up
SG2010 Chipset
The StarGen SG2010 chipset functions at the core of the PCI-SB card to provide
the bridge functionality and capability to convert PCI bus traffic into serial frame
format StarFabric signals for transmission across the switch fabric or directly to
remote StarFabric-enabled bridges.
Dual StarFabric Serial Links
Two pairs of RJ-45 connectors provide the interface for the dual 2.5 Gbps StarFab-
ric serial links. You can aggregate the dual RJ-45 ports for full 5.0 Gbps speed
using path routing for higher bandwidth. Or, you can provide redundant links
between StarFabric-enabled devices to increase reliability. Path routing requires
custom software development using the Fabric Primitives Library included on the
CD-ROM shipped with your PCI-SB card.
Refer to “Networking StarFabric Devices” on page 2-17 for more details on inter-
connecting StarFabric-enabled devices.
DIP Switches
DIP switches control the cards operational modes. You use these switches to set
the PCI-SB card for Root or Leaf operation as a bridge. See “PCI-SB Card Operat-
ing Modes” on page 2-11 for details on Root and Leaf modes.
Eight LEDs
Two rows of Green LEDs (four lights per row) show the operational status of the
PCI-SB cards ports based on the four pairs of Low Voltage Digital Signalling
(LVDS) wires in each link. Each LED represents one LVDS pair on each link.
