Black Box LGB5028A-R3 Ethernet Switch - LGB5000 Series Gigabit Ethernet (1000 Mbps) Managed Switch (24) 10/100/1000 Mbps Copper RJ45, (4) 100/1000 Mbps SFP+, (1) DB9 Console 24 Ports Manageable Gigabit Ethernet 10/100/1000Base T, 1000Base X 2 Layer

This high-performance switch uses LACP and IEEE 1588v2 to optimize network operations.

LACP is used in high-availability and performance environments, such as data centers or enterprise networks, to aggregate links between switches, servers, or routers. It simplifies management by treating multiple links as one, and improves resilience by avoiding single points of failure. LACP scales network capacity without upgrading individual links.

IEEE 1588v2, also known as Precision Time Protocol (PTP), is a standard protocol used to precisely synchronize clocks across a network. This is important in applications that require highly accurate timing, such as telecommunications, industrial automation, power systems, and financial services.

Fully manageable

The switch is fully managed, supporting SNMP version 1, 2c, and 3. The embedded RMON software agents support RMON groups 1 (history), 2 (statistics), 3 (alarms), and 9 (events). The integral Web server enables Web-based management via a Web browser. This GUI interface enables switch configuration, system dashboard, maintenance, and monitoring, and includes a wide range of management and support features.

Support for VLAN and QoS

Support for up to four simultaneous VLANs segments traffic with port-based, 802.1Q tag-based, or MAC-based VLANs. 802.1p Layer 2 quality of service (QoS) prioritizes time-sensitive applications such as VoIP and video.

Secure

Enterprise-class security features include 802.1X port-based network access control to authenticate devices connecting to your network. The switch also supports SNMPv3 cryptographic security, SSH, and SSL. Plus, you can set up a guest VLAN that enables visitors to access the Internet without also giving them access to the corporate network.

Green

IEEE 802.3az energy-efficient Ethernet scales down power consumption during periods of low data activity, saving 50% energy. Cable length detection adjusts signal strength to the cable length, reducing power consumption on shorter cable runs.
