HUAWEI S1720-28GWR-PWR-4P S1700 Series Switches

S1720-28GWR-PWR-4P Gigabit PoE Access

S1720-28GWR-PWR-4P combines 24 10/100/1000BASE-T powered access ports with four 1000BASE-X optical uplinks. It preserves the 4P Gigabit-uplink layout of the non-PWR model while adding endpoint power capability.

Forwarding profile

Huawei lists 68 Gbit/s switching capacity and 42 Mpps forwarding for the 28-port GWR-P family. Treat this as a GE access and GE optical aggregation design, not a four-port 10GE platform.

PoE sizing gate

The exact usable PoE budget depends on the delivered power configuration and hardware record. Build an endpoint power schedule from IEEE class, startup draw and operating margin, then verify it against the serialized unit rather than assuming all 24 ports can supply maximum power simultaneously.

Media and management

Validate each 1000BASE-X optic and configure management isolation, VLANs, loop protection and backup. Huawei identifies the exact model under the S1700/S2700 V200R022C00 product family.

Receiving checks

Confirm the full PWR-4P suffix, test representative powered endpoints and all four GE optical links, and record software, power input and thermal behavior before deployment.

Official evidence: Huawei S1720 official specifications and Huawei exact S1720-28GWR-PWR-4P record.
