Level One GEP-2671 User Manual

GEP-2671 Version: 1

26-Port L2 Managed Gigabit PoE Switch,

802.3af/at PoE, 24 PoE Outputs, 4 x SFP/RJ45
Combo, 2 x SFP, 185W

The LevelOne GEP-2671 is a Layer 2 Managed switch with 24 x 1000Base-T PoE-Plus ports associated
with 4 x Gigabit SFP (Small Form Factor Pluggable) slots + 2 individual Gigabit SFP Slots. This switch is
IEEE 802.3af/at compliant to provide power and data over a single Ethernet cable to the PoE device, with
total power budget of 185W, up to 30W per port.

Despite its affordable pricing, the GEP-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.

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.
