CE5855-48T4S2Q-EI Overview Huawei CE5855-48T4S2Q-EI Switch(48-Port GE RJ45,4-Port 10G SFP+,2-Port 40G QSFP+,Without Fan and Power Module). Huawei CloudEngine 5800 series (CE5800) switches are next-generation, high-density Gigabit Ethernet switches designed for data centers and high-end campus networks. The CE5800 hardware has an advanced architectural design with the industrys highest density of GE access ports. The CE5800 is also the first Gigabit Ethernet access switch to provide 40GE uplink ports. Using the Huawei VRP8 software platform, CE5800 switches support Transparent Interconnection of Lots of Links (TRILL) and have a high stacking capability (up to 16-member switches in a stack system).
