CE6881-48T6CQ-B Overview The CloudEngine 6800 switches feature advanced hardware design with 10GE/25GE access interfaces, 40GE/100GE uplink interfaces, advanced data center features, high-performance stacking technologies, and flexible airflow capabilities. They are ideal for the core or aggregation level. Together with the CloudEngine 16800 and 12800 series switches, the CloudEngine 6800 enables you to build scalable, simplified, open and secure networks. CE6881-48T6CQ-B Specification Item Description Physical specifications Weight (with two power modules and two fan modules, calculated based on the heaviest model if multiple models are supported): 8.5 kg Environment parameters Temperature Operating temperature:Operating temperature: 0C to 40C (32F to 104F) at altitude of 0-1800 m (0-5906 ft.) NOTE: When the altitude is 1800-5000 m (5096-16404 ft.), the highest operating temperature reduces by 1C (1.8F) every time the altitude increases by 220 m (722 ft.). Storage temperature: -40C to +70C (-40F to +158F) Relative humidity 5% RH to 95% RH, noncondensing Altitude lt, 5000 m (16404 ft.)
