Huawei CE6810-48S4Q-LI 48-Port 10GE Data Center Switch

CE6810-48S4Q-LI High-Density Optical Leaf Switch

CE6810-48S4Q-LI is the 48-port optical LI variant in Huawei's legacy CE6810 family. It exposes 48 SFP+ service positions and four QSFP+ positions, giving it twice the SFP+ and QSFP+ counts of CE6810-24S2Q-LI and a different oversubscription and cabling profile.

Density and failure domains

Document which of the 48 SFP+ interfaces serve hosts, appliances or downstream switches and which QSFP+ links provide upstream, peer, breakout or stack connectivity. Model the bandwidth and maintenance impact of losing one uplink before assigning all four QSFP+ ports.

Release-specific behavior

Huawei's Smart Link table lists V100R003C10 as the minimum release for CE6810-48S4Q-LI and CE6810-48S-LI. This is model-specific evidence rather than a general software recommendation. Confirm the actual supported release, patch, license state and transceiver matrix for the serialized chassis before migration.

Optics and airflow BOM

Build the order around verified Huawei-supported SFP+/QSFP+ media, cable reach and breakout requirements. Check airflow direction and whether the quoted chassis includes the required fan and power modules; record redundant power and spare-optics policy separately.

Receiving and cutover

Verify the full 48S4Q-LI model label, 48 SFP+ and four QSFP+ positions, serial and software version. Test representative optics, management access, power redundancy and the planned uplink topology before moving production traffic.
