FlexFabric 7904 Switch Chassis

The HPE FlexFabric 7904 is a manageable Layer 3 switch chassis designed for data-centre and campus aggregation layers. It fits a 2U rack footprint and provides four expansion slots for Network Interface Modules, allowing administrators to tailor port density and media type to the network design.

Four Expansion Slot Architecture

Each of the four slots accepts a Network Interface Module, so the total I/O count depends entirely on the modules chosen. The chassis itself supplies the switching fabric and management plane but contributes no fixed ports, meaning capacity scales only when modules are populated and the backplane bandwidth they require is available.

Modular Capacity and Physical Limits

The 2U form factor measures 3.5 inches high, 17.3 inches wide and 28.4 inches deep, weighing approximately 50.04 pounds, which constrains how many chassis can be stacked in a standard rack. Once all four slots are filled the chassis reaches its port and throughput ceiling, so networks that anticipate growth beyond four modules will need additional chassis or a larger platform.
