Tested SFP modules
The Uplevel switches’ SFP cages have been tested with the TP-LINK TL-SM311LM Gigabit SFP module — a 1000Base-SX multi-mode fibre mini-GBIC with an LC/UPC interface, supporting up to 550 m (multi-mode) or 220 m at the longer-distance setting, plug-and-play.
Wiring SFP ports
The SFP ports on every Uplevel switch follow the same convention as the RJ-45 Ethernet ports: an “uplink” goes toward the gateway, and ordinary “LAN” ports go toward downstream devices.
- SFP1 and Uplink SFP are uplink ports — connect them to an Uplevel Gateway, or to a LAN port on an upstream switch.
- The remaining SFP cages behave as regular LAN ports. Connect them to the uplink port of downstream switches when chaining.
If you’ve cabled a copper Uplevel switch stack before, the SFP case is identical: LAN port to uplink, LAN port to uplink, all the way down.
