Black Box, LGB5028A, Managed Gigabit Ethernet Switch, 28-Port
The Gigabit Ethernet Managed Switch adds 28 high-speed ports, including four 10-GBE SFP+ ports, while offering the management and security features your enterprise network needs. This capable Layer 2 switch offers 20 auto sensing 10-/100-/1000-Mbps RJ-45 Ethernet ports. It also has four dual-media ports, each of which consists of an 10-/100-/1000-Mbps RJ-45 port plus an SFP port. These dual-media ports can be used either as a normal UTP Ethernet porter adapted to 100- or 1000-Mbps fiber through the use of an SFP. Additionally, the switch features four SFP+ ports which support 1- or 10-Gbps uplinks through the use of SFP+ transceivers.
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 Web browser. This GUI interface enables switch configuration, system dashboard, maintenance, and monitoring. The wide range of management and support features also includes dual image, port mirroring, LLDP, sFlow, UPnP, IPv6, SSH, RADIUS, DHCP Client/DHCPv6 Client, SNTP, cable diagnostics, ping, syslog, and Telnet client with SSH security.
Support for VLAN and QoS
Support for up to four simultaneous VLANs enables you to segment traffic with port-based, 802.1Q tag-based, or MAC-based VLANs. 802.1p Layer 2 quality of service (QoS) enables prioritization of time-sensitive applications such as VoIP and video.
Secure
You get enterprise-class security features, too. 802.1X port-based network access control authenticates 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
The Gigabit Ethernet Managed Switch features IEEE 802.3az energy-efficient Ethernet, which scales down power consumption during periods of low data activity. This feature adds up to energy savings of up to 50%. Cable length detection adjusts signal strength to the cable length, reducing power consumption on shorter cable runs.
Features:
- Provides (20) 10/100/1000BASE-T UTP ports, (4) dual-media UTP/SFP ports, and (4) SFP+ ports that support speeds up to 10 Gbps.
- Full SNMP management plus Web-based management and console port.
- Support for VLAN and QoS.
- Supports IEEE 802.1x port-based network access control.
- 802.3az Energy-Efficient Ethernet saves on power costs.
