S3700-28TP-EI-DC Overview
Build a media map for the two dual-purpose connections
The 28TP order description separates twenty-four Fast Ethernet access ports, two Gigabit SFP positions and two dual-purpose positions. For each dual-purpose connection, specify whether the intended link uses copper Ethernet or SFP. Do not produce a bill of materials by adding every visible connector as an independent interface. Retain the two dedicated SFP links in a separate part of the connection schedule and check the actual interface numbering in the equipment guide.
Keep the access-speed requirement explicit
An endpoint connected through one of the twenty-four access ports has a manufacturer-listed 10/100 interface. The 10/100/1000 wording applies to the dual-purpose interfaces, not to the entire copper access bank. This distinction matters when replacing a switch for devices that now require Gigabit copper access. Record which endpoint connects to each port and whether the project needs a different access-switch generation.
Use the DC order identity at the installation handoff
The precise pairing is S3700-28TP-EI-DC and BOM 02352349. Huawei marks this order description DC −48V, which does not by itself define all acceptable input limits or the installed power terminal arrangement. Include the model and BOM in the installer’s acceptance sheet and obtain the complete supply specification from the chassis label and its hardware instructions. Verify wiring and grounding before energizing the offered unit.
Quote a release-aware optical configuration
Huawei’s matched-parts view identifies V100R005C01 as the first-supported version and shows eSFP-GE-SX-MM850 and SFP-GE-LX-SM1310 among the optical choices. Specify the intended copper/SFP media selection, software release and optical module code together so the compatibility check covers the actual design. The matching table does not prove what firmware is installed or what optics are supplied. Ask for separate accessory quantities, current service terms and an itemized delivery configuration.
