CE7855-EI-B-B0A Overview
Huawei CloudEngine 7800 series (CE7800 for short) switches are next-generation 40G Ethernet switches designed for data centers and high-end campus networks, providing high-performance, high-density 40GE ports, and low latency. The CE7800 has an advanced hardware architecture with 40GE QSFP+ ports. Using the Huawei VRP8 software platform, CE7800 switches provide extensive data center service features and high stacking capability. In addition, the airflow direction (front-to-back or back-to-front) can be changed.
