Huawei CloudEngine S5751-L4LP8UN2X-RUA 12-Port Mixed Gigabit/Multigigabit PoE Campus Remote Unit Access Switch
Quick Buying Guide - Best for Campus remote-unit access
-
Deployment fit: Campus remote-unit access. Enterprise offices, Education, Hotels, Healthcare.
-
Interfaces: 4 x GE Base-T PoE+; 8 x GE/2.5GE Base-T (4 PoE+, 4 PoE++); 2 x 100M/1/2.5/10GE SFP+.
-
PoE planning: Huawei ordering information specifies a 128 W PoE budget with one AC power adapter; its full-load power-consumption table uses a 125 W PoE load, so reserve headroom when sizing powered endpoints.
Selection note from Certified Experts: Choose this configuration when enterprise offices calls for 4 x ge base-t poe+; 8 x ge/2.5ge base-t (4 poe+, 4 poe++) and 2 x 100m/1/2.5/10ge sfp+; confirm software and power options against the final bill of materials.

PoE Budget Planning
For a Huawei S5751-L4LP8UN2X-RUA deployment, multiply each powered device's datasheet maximum input by its quantity, then add a 25% planning reserve (not an IEEE requirement). Huawei ordering information specifies a 128 W PoE budget with one AC power adapter; its full-load power-consumption table uses a 125 W PoE load, so reserve headroom when sizing powered endpoints. Check the per-port power class and available powered-port count; a per-port maximum is not the same as the total switch budget. Calculate your project PoE budget before finalizing power supplies and endpoints. The result is a planning estimate, not a compatibility guarantee.
