CE7855-32Q-EI Switch(32-Port 40GE QSFP+,2*AC Power Module,2*FAN Box,Port-side Intake)
The switch provides high-performance, high-density 40GE ports, and low latency. The CE7800 hardware has an advanced architectural design with 40GE QSFP+ports. By using Huawei VRP8 software platform, CE7855-32Q-EI offers extensive data center servicefeatures and high stacking capability. In addition, the airflow direction (front-to-back or back-to-front) canbe changed. CE7800 switches can also work with CE12800/CE8800/CE6800/CE5800 switches to build an elastic,virtualized, high-quality fabric that meets the requirements of cloud-computing data centers. Moreover, CE7855-32Q-EI can function as core or aggregation switches on data center networks to help enterprisesand carriers build a scalable data center network platform in the cloud computing era. They can also be usedas aggregation or core switches for enterprise campus networks.
