HUAWEI CE5855-48T4S2Q-EI CE5800 Series Switches

CE5855-48T4S2Q-EI 48-Port Copper Leaf Switch

CE5855-48T4S2Q-EI is the 48-copper-port member of Huawei's CloudEngine CE5855 family. Huawei documents 48 10/100/1000BASE-T downlinks, four 10GE SFP+ uplinks and two 40GE QSFP+ interfaces, positioning the unit for high-density Gigabit server access or a leaf role.

48-port rack design

Map all 48 copper server or appliance links before reserving the four 10GE and two 40GE interfaces for upstream, peer or stack use. Record oversubscription, VLAN and failure-domain assumptions; port count alone does not establish that every uplink can carry the intended aggregate load.

Power and airflow BOM

Huawei's official brochure states that the base CE5855-48T4S2Q-EI does not include power supplies or fan modules. Select compatible power and airflow-direction modules as explicit line items, keep intake and exhaust direction consistent across the rack, and verify redundancy against the actual shipment.

40GE stacking constraint

Huawei's maintenance documentation distinguishes this 48-port model from the 24-port unit: the two 40GE ports on CE5855-48T4S2Q-EI cannot both be added to the same stack port. Review the target software release and Huawei's current stack guidance before assigning QSFP+ links.

Receiving evidence

Verify the exact CE5855-48T4S2Q-EI label, count 48 RJ45, four SFP+ and two QSFP+ interfaces, and reconcile power supplies, fans, optics and cables separately. Preserve the supported software version and airflow BOM with the device serial.

Official evidence: Huawei exact CE5855-48T4S2Q-EI support portal, Huawei CloudEngine 5800 brochure and Huawei CE5855 stacking limitation.
