Black Box LIG1000 network media converter 1000 Mbit/s

Six ports for flexibility
This switch has six 10/10/1000-Mbps RJ-45 copper ports that are autosensing. It offers full wire-speed forwarding rates, auto-negotiates for network speeds, and Auto-MDI/MDI-X, eliminating the need for crossover cables. The two 100/1000 Ethernet SFP slots give you networking flexibility and scalability. You can extend your network over multimode or single-mode fiber at distances up to 80 kilometers, depending on the SFP you choose. Black Box SFPs are recommended.

Maximize uptime
Advanced management features help minimize network downtime by enabling you to remotely diagnose and manage network problems. You'll also eliminate the need to send IT technicians on site - thus lowering costs.

The switch is fully manageable through SNMP, a Web browser, Telnet, or a console port. Control the bandwidth on each port individually and set up Quality of Service (QoS) priority queuing for critical applications.

The switch supports port-based VLAN and IEEE 802.1Q VLAN tagging, MAC-based trunking, IP-multicast IGMP snooping, rapid spanning tree for redundancy. Plus, it has 802.1x port-based authentication for security.

Fast failovers.
For redundancy, the switch has two DC power inputs. If one power source fails, the switch automatically falls over to the second power source. It offers a 20 millisecond or less failover. In addition, an alarm will alert you in case of a power failure. The switch also gives you maximum network flexibility: Spanning Tree Protocol (STP/RSTP), Link Aggregation Control Protocol, and a ring protocol.
