How many units U is Huawei s 12808 core switch

The Huawei CloudEngine 12808 core switch is a 14U rack-mountable chassis.The CE12808 is a high-performance, modular core switch designed for data center and high-end campus networks, supporting up to 178 Tbps switching capacity (scalable to 1032 Tbps) and a large number of line-rate ports including 100GE, 40GE, 25GE, and 10GE . Its chassis is designed to accommodate multiple horizontally installed modules: 2 MPU slots, 2 CMU slots, 8 LPU slots, 6 SFU slots, 8 power module slots, and 13 fan module slots . This modular architecture ensures high reliability, redundancy, and scalability for large-scale deployments.Physical and Installation DetailsRack Units (U): 14U, suitable for standard 19-inch server racks.Module Installation: MPUs, SFUs, and LPUs are horizontally installed, allowing easy access and replacement .Power and Cooling: Supports redundant power supplies (e.g., PHD-3000WA) and front-to-back airflow for industrial-grade reliability .Virtualization and Management: Supports device virtualization (VS) and cluster switch system (CSS) for logical device partitioning and simplified network management . This 14U form factor is typical for high-end modular core switches, balancing port density, redundancy, and airflow requirements while fitting into standard data center racks. It is important to plan for additional clearance above and below the chassis for airflow and cabling.
