HUAWEI S1720-52GWR-PWR-4X S1700 Series Switches

S1720-52GWR-PWR-4X Dense PoE with Four 10GE Uplinks

S1720-52GWR-PWR-4X pairs 48 powered 10/100/1000BASE-T downlinks with four 10GBASE-X optical uplinks. It is the high-uplink-speed option within the 52-port GWR PWR range.

Forwarding performance

Huawei specifies 336 Gbit/s switching capacity and 132 Mpps forwarding for the 52-port GWR-X family. The 10GE optical set reduces aggregation constraints compared with the PWR-4P model, whose uplinks are 1000BASE-X.

PoE verification

Obtain the serialized power configuration and calculate the complete endpoint schedule. Include normal draw, startup peaks, redundancy expectation and thermal margin; do not publish or design around an unverified generic wattage.

Distribution integration

Confirm supported 10GE optics, fiber plant and peer compatibility, then test loop protection and failure recovery. Isolate management access and retain configuration and entitlement records for the installed release.

Lifecycle gate

Huawei Info-Finder maintains an exact S1720-52GWR-PWR-4X product identity. Check current lifecycle and support expectations for older stock and preserve the full suffix in replacements.
