GEL-2671 version: 1 26-port l2 managed gigabit ethernet switch, 4 x sfp/rj45 combo, 2 x sfp the levelone GEL-2671 is a layer 2 managed switch with 24 x 1000base-t ports associated with 4 x gigabit sfp (small form factor pluggable) slots + 2 individual gigabit sfp slots. despite its affordable pricing, the GEL-2671 is equipped with advanced features such as single ip management which allows users to manage up to 32 switches under the same web interface, easy configuration port (ecp), igmp v1/v2/v3, ipv6, ieee 802.1d/w/s spanning tree, ieee 802.1x access control of up to 256 entries for easy network security, auto port aggregation, ieee 802.1p qos with 8 priority queues, ieee 802.3az green ethernet and more. an ideal network solution for workgroups and edge deployments, or anyone looking for an affordable and efficient way to expand their network. key features - 10/100/1000mbps wire speed transmission and reception - easy configuration port (ecp) for easy deployment of network devices such as ip phone or network camera - single ip management supports up to 32 switches (gel-1072/gtl-2880/gtp-2880/gtl-5280/gep-2671/gep-2672) - ieee 802.1p qos with 8 priority queues - supports access control list (acl) authentication of up to 256 entries and port-based security with ieee802.1x - supports ipv4/ipv6 network operation - ieee 802.1d/w/s spanning tree protocol (stp) and port mirroring - ieee 802.1q vlan allows network segmentation to enhance performance and security - supports dual firmware image which protects against failed firmware upgrade www.level1.com page 1 of 5
- minimize carbon footprint with advanced energy efficient technology (ieee 802.3az) - ieee 802.3ad lacp for auto port aggregation highlight ip clustered stacking solution with the design and implementation of sip (single ip management), network administrators are allowed to virtually stack up to 32 switches (gel-1072/gtl-2880/gtp-2880/gtl-5280/gep-2671/gep-2672) together and manage them as one logical unit through a single ip address regardless of geographical locations of those switches. comparing to traditional stacking, ip clustering eliminates the use of costly cables and connectors. furthermore, it minimizes the impact of any single point of failure. levelone easy configuration port (ecp) technology each switch port can now be fully optimized through a predefined role and settings which are based on the type of a device such as an ip camera or a voip phone to be connected to. for instance, even if a surveillance system integrator who lacks of it administration skills, can still easily enables the role and applies settings like vlan, qos, port security and spanning tree to all connected ip cameras on a single web ui within a few minutes. hence, simplifying network deployment and ensuring consistent configurations across the network. specifications system specifications standards & protocols: ieee 802.3 10-base-t, ethernet ieee 802.3u 100-base-tx, fast ethernet ieee 802.3ab 1000base-t, gigabit ethernet ieee 802.1p quality of service (qos) ieee 802.1x port-based network access control (pnac) ieee 802.1q virtual lans (vlans) ieee 802.1d mac bridges ieee 802.1d standard spanning tree protocol ieee 802.1s multiple spanning tree (mstp) ieee 802.1w rapid spanning tree protocol (rstp) ieee 802.3ad link aggregation control protocol (lacp) ieee 802.3az energy-efficient ethernet link layer discovery protocol (lldp) universal plug and play (upnp) buffer memory: 512kb connectors and cabling: 24 x rj-45 10/100/1000base-t ports 6 x 100/1000base-x sfp slots (4 shared) button: reset button indicator: power, link/active transmission method: store-and-forward power: power consumption: < 22.8w power input: 100-240v ac, 50-60 hz, internal power supply features www.level1.com page 2 of 5
