HPE R0X45A – 12-Port 40/100 GbE QSFP28 Line Card
Overview
The HPE R0X45A is a high-capacity line card designed for the HPE/Aruba CX 6400 modular chassis family, intended for network engineers who require high-speed uplink or spine-level bandwidth. If you’re operating in a campus core, aggregation layer or compact data-centre rack and need to push fiber links of 40 Gb or 100 Gb to adjacent switches or network fabrics, this module plugs into the chassis to provide 12× QSFP28 ports capable of 40/100 Gb each. It fits inside the CX 6400 chassis (for example the 6405 or 6410 chassis) and benefits from the overall chassis management, high availability, cooling & power infrastructure. The module is ideal in environments where you need more than standard uplinks—this gives you dedicated high-speed ports in one module slot for backhaul, spine interconnect or dense uplink aggregation.
Key Features
- Twelve QSFP28 ports rated for 40 Gb or 100 Gb operation—enabling high-bandwidth uplinks in a modular chassis.
- Designed specifically for the Aruba CX 6400 series chassis—ensures full compatibility with platform features and chassis resources.
- Suited for spine/aggregation or uplink roles in enterprise or data-centre networks rather than access-layer device ports.
- Enables consolidation: instead of separate switches for high-speed uplinks, you utilise the chassis with this module to centralise high-speed fabrics.
- High performance: supports 100 Gb ports per slot and built to operate in rich switching environments with substantial throughput demands.
