Designed for rugged environments, the LEH1104A-2SFP Ethernet Switch gives you the high reliability you need. Use this managed switch to configure, control, and monitor remote equipment in the worst environments. Because it supports PoE+, you can use it to power remote PoE devices through your Ethernet lines.
Advanced management features will help you minimize network downtime by enabling you to remotely diagnose and manage network problems. You'll lower operational expenses, too, by eliminating the need to send IT technicians on site to troubleshoot and access network equipment. The switch is fully manageable through SNMP, RS-232, a Web browser, Telnet, or a console port. You can control the bandwidth utilization on each port individually as well as set up Quality of Service (QoS) priority queuing for critical applications. The LEH1104A-2SFP supports port-based VLAN and IEEE 802.1Q VLAN tagging, MAC-based trunking, IP-multicast IGMP snooping, rapid spanning tree for redundance, and port mirroring. It also has 802.1x port-based authentication for security.
The switch gives you maximum network flexibility wiht two methods for maintaining network resiliency: Spanning Tree Protocol (STP/RSTP) and Alpha-Ring protocol. The switch can also help you maximize network uptime by enabling failover links with a 30 millisecond or less failover. With STP, you can set up redundant links to provide automatic backup paths if an active link fails. It also avoids the creation of bridge "loops" that cause broadcast storms. In addition, you can also seamlessly incorporate the Alpha-Ring into existing STP networks for greater redundancy. Expand bandwidth with Link Aggregation Control Protocol (LACP 802.3ad) by combining links and providing another method of network redundancy.
The switch features redundant power inputs and includes a DIN-rail mount. The panel and power supplies (SDR-240-48) are sold separately. The switch also includes a serial cable (DB9 M/F) for the console connection. Encased in an IP30-rated metal case, this switch withstands extreme temperatures ranging from -40°C to +75° C. The switch complies with multiple environmental standards.
