- Flexible. SFP slot enables you to define distances from 500 meters to 10 kilometers.
- Applicable for data backhaul applications.
- Full SNMP management plus Web-based management.
- Support for VLAN and QoS.
- Supports IEEE 802.1x port-based network access control.
- 802.3az Energy-Efficient Ethernet saves on power costs.
The Gigabit Ethernet Managed Switch adds 26 high-speed ports—including two dual-media ports—while offering the management and security features your enterprise network needs.
This capable Layer 2 switch offers 24 autosensing 10-/100-/1000-Mbps RJ-45 Ethernet ports. It also has two dual-media ports, each of which consists of a 10-/100-/1000-Mbps RJ-45 port plus an SFP port. These dual-media ports can be used either as a normal UTP Ethernet port or adapted to 100- or 1000-Mbps fiber through the use of an SFP. The UTP ports support PoE+ with a power budget of 185 watts.

Video switching

This switch features Black Box's MediaCento software giving you HDMI-over-IP video distribution and video switching. You'll be able to multicast HDMI video over an IP network to an unlimited number of distant screens for faster, more efficient HD content distribution. Or use the switch for distributing digital signage content or other HD video across an Ethernet network. To unlock the software, you'll need to purchase the one-time license (LPB2900A-CTRL).

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. VoIP traffic is automatically assigned to a voice-specific VLAN to maintain quality. 802.1p Layer 2 quality of service (QoS) enables prioritization of time-sensitive applications such as VoIP and video.


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.


The PoE+ Gigabit Managed Switch Eco 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.
