Ports on the S5731S-L4P2HW-RUA

Port Connector Type Description Available Components
10/100/1000BASE-T PoE++ port RJ45 A 10/100/1000BASE-T PoE++ Ethernet electrical port sends and receives service data at 10/100/1000 Mbit/s.

The port supports the PoE function.

Ethernet cable
1000BASE-X hybrid optical-electrical port SFP A 1000BASE-X hybrid optical-electrical port can send and receive data at 1000 Mbit/s. It can receive PoE power from a central switch through a hybrid cable.
  • Industrial optical modules (only optical modules with 1 Gbit/s transmission speed and transmission distances less than or equal to 10 km are supported)
  • Optical module dedicated for hybrid cable (SFP-GE-Hybrid)
  • Second-generation hybrid cable
