Device Description
2.1
Introduction to the Device
The
LP-SGW 2404FP switch, designed for workgroups and departments,
provides wire-speed performance and abundant layer 2 management features. It
provides a variety of service features and multiple powerful functions with high
security.
The EIA-standardized framework and smart configuration capacity can provide
flexible solutions for a variable scale of networks. ACL, 802.1x and Dynamic ARP
Inspection provide robust security strategies. QoS and IGMP snooping/filtering
optimize voice and video application. Link aggregation (LACP) increases
aggregated bandwidth, optimizing the transport of business critical data. SNMP,
RMON, WEB/CLI/Telnet Log-in bring abundant management policies. The
LP-SGW 2404FP switch integrates multiple functions with excellent performance,
and is friendly to manage, which can fully meet the need of the users demanding
higher networking performance.
LP-SGW 2404FP Managed PoE Switch is also a Power Sourcing Equipment
(PSE*). All the Auto-Negotiation RJ45 ports on the switch support Power over
Ethernet (PoE*) function, which can automatically detect and supply power with
those powered devices (PDs*) complying with IEEE 802.3af and IEEE 802.3at.
PSE:
A device (switch or hub for instance) that will provide power in a PoE setup.
PoE:
This technology describes a system to transmit electrical power, along with
data, to remote devices over standard twisted-pair cable in an Ethernet.
PDs:
A device powered by a PSE and thus consumes energy. Examples include
powering IP telephones, wireless LAN access points, network cameras,
network hubs, embedded computers etc.
