CE6851-HI-B-B0A-AC Dual
Product Overview
The Huawei CE6851-HI-B-B0A-AC Dual is a high-performance, 1U data center switch from the CloudEngine 6800 series. It is purpose-built for high-density 10GE and 40GE connectivity, making it an ideal solution for top-of-rack (ToR) and end-of-row (EoR) deployments in enterprise and cloud data centers.
This model features 48 fixed 10GE SFP+ ports and 6 fixed 40GE QSFP+ ports, delivering a switching capacity of 1.44 Tbit/s and a forwarding rate of 1,080 Mpps. The device is equipped with dual AC power supplies and dual fan boxes, configured with port-side exhaust airflow. The power modules support 1+1 redundancy, while the four internal fans operate in a 3+1 backup mode. All power and fan modules are hot-swappable, contributing to high system availability.
The switch supports flexible stacking via its 10GE optical and 40GE optical ports, enabling the creation of a high-capacity, resilient virtual chassis. The CE6851-HI-B-B0A-AC also features advanced hardware capabilities, including a 1.2 GHz quad-core processor, 2 GB of DRAM, and 1 GB of NAND flash memory.
