Huawei S3700-28TP-SI-DC 24-Port FE -48V Switch 02352368

S3700-28TP-SI-DC exact DC configuration

Huawei S3700-28TP-SI-DC is official part number 02352368. Huawei lists 24 Fast Ethernet RJ45 access ports, two Gigabit combo interfaces, two additional Gigabit SFP interfaces and -48 V DC input.

Combo-port accounting

The two GE combo positions each provide alternative copper or SFP media for the same logical interface; both sides of a combo pair cannot be counted as independent simultaneous ports. The other two GE SFP interfaces are separate. Procurement and cabling plans must preserve this distinction.

DC, non-PoE deployment

This SI-DC chassis is not a PWR model and Huawei's exact description does not identify PoE on the 24 FE access ports. It is intended for -48 V DC infrastructure. Confirm site feed polarity, protective devices, grounding and the required DC cable assembly before installation.

Migration checklist

Record part number 02352368, VRP version, stack peers, VLAN and uplink configuration, optics and rack accessories. The 28TP DC model must not inherit the 52-port PoE page's AC power-module or endpoint-power claims.
