·OVERVIEW ? INDUSTRIAL MANAGED AND UNMANAGED GIGABIT ETHERNET SWITCHES DATA SHEET INTRODUCTIONThe Industrial Managed and Unmanaged Gigabit Ethernet Switches include unmanaged switches that provide four (4) copper RJ-45 or RJ-45 PoE ports and one (1) multi-rate SFP slot and managed switches that provide six (6) or eight (8) copper RJ-45 or RJ-45 PoE ports and two (2) or four (4) multi-rate SFP slots.Power over EthernetThe LIE401A, LIE1014A, LIE1080A and LIE1082A switches support Power over Ethernet compliant to the IEEE 802.3af and IEEE 802.3at standard on all copper ports. These switches can be used to power standard PoE PD devices with up to 30 watts per port along with the Ethernet data on standard Ethernet Cabling.Multi-rate SFP slotsThe benefit of having multi-rate SFP slots is to be able to use 100-Mbps and 1-Gbps SFP Modules for either multi- or single-mode in a mix and match as needed. If requirements change, just replace the SFP module and protect your switch investment.PowerThe switches are powered from 12- to 58-VDC. The PoE models need 48 VDC for 802.3af and a minimum of 53 VDC for 802.3at.Extended temperature rangeAll models are tested and released for operating temperatures from -40° up to +75° Celsius.ManagementThe switches offer powerful features including Layer 2 routing and management with all advanced filter and multicast algorithms needed today to easily prioritize, partition, and organize a reliable high-speed network.
