ExpressBox 7 - RAS

Seven Slot PCI Express® Expansion Chassis with SNMP & Redundant Power

ExpressBox 7 - RAS is built with modularity and scalability in mind and provides 7 full-length PCI Express slots all in a 4U form factor.

    SKU: eb7-x8g2-ras

    The EB7-X8G2-RAS is built with modularity and scalability in mind. It has an Expansion Interface Card installed in one PCI Express slot in the chassis that provides x8 Lanes of PCI Express connection to the Host. The Expansion Interface Card can be replaced with an optical card that allows for connection with Host over Fiber.

    Seamless expansion of System capabilities

    The EB7-X8G2-RAS, with its companion Host Card and high-performance cable, extends the PCI Express bus out of the Host and allows for seamless integration of up to 7 PCI Express I/O cards per chassis.  The EB7-X8G2-RAS can be easily transformed into a Host Computer with 8 slots when a Root Complex card is installed in place of the Expansion Interface card in the chassis.

    Optimal method to enhance your PCI Express I/O capabilities

    The EB7-X8G2-RAS is an expansion chassis in 4U height that provides 7 full-length PCI Express slots. These chassis can be daisy-chained while giving up one usable slot per chassis excepting for the last one in the chain. The total number of PCI Express slots derived will be determined by the number of root complex ports supported by the Host.
