The Environmentally Hardened Managed Ethernet Switch from ComNet provides eight 10/100 BASE-TX ports and two 10/100/1000TX or 100/1000FX combo ports. The switch is designed for use in difficult environments, and is available for use with CAT5e copper or optical transmission media. The eight electrical ports support the 10/100 MB/s IEEE 802.3 protocol.

The switch features auto-negotiating and auto-MDI/MDIX to assist installation. All eight ports support IEEE 802.3af Power over Ethernet (PoE). Two ports are 10/100/1000 configurable for copper or fiber media by selected SFP modules that are sold separately. These network-managed layer 2 switches are optically (100/1000 BASE-FX) and electrically compatible with any IEEE 802.3 compliant Ethernet devices.
