Expansion Link Board (ELB-SHB)
PCI Express x8 Expansion Link Board fits into the
system slot of an SHB Express (PICMG 1.3) compliant backplane
in a downstream expansion chassis.
OSS-SHB-ELB-x8
Product Features
- x8 PCI Express connector on slot cover
- Upstream/downstream lane active LEDs on slot cover
- PCI Express links through the PICMG
1.3 card edge connector
- 20 lanes of PCI Express are auto configurable
- Power acceptable LEDs on board
- Optional power connector for embedded applications
without a backplane

The Expansion Link Board (ELB) is inserted into a downstream SHB
Express (PICMG 1.3) compliant backplane. The ELB is a downstream
cable link board and the primary fan-out switch to support multiple
configurations of PCI/PCI-X or PCIe expansion slots. Twenty lanes
of PCIe are auto-configurable on the card edge connector of the
ELB.
When implemented with a MaxExpress Host Interface Board (HIB) an expansion sub-system and a PCIe standard cable, a driverless, standards-based expansion system is achieved.
