2. Overview
2.1 Introduction
LPB708A/LPB716A/LPB724A, is a standard 8-Port/16-Port/24-Port 10/100 PoE PSE Web Smart Switch that meets all
IEEE 802.3u/x Ethernet specifications. The switch includes 8-, 16-, or 24-Port 10/100Mbps TP ports. LPB724A also
features two combo UTP/SFP Gigibit ports. Manage the switch through an Ethernet port using Web-based management.
The switch also features QoS (Quality of Service), Spanning Tree, VLAN, Port Trunking, and IGMP Snooping capability
via the intelligent software. It is suitable for small- and medium-sized office applications.
This PSE switch also complies with IEEE 802.3af. Its advanced autosensing algorithm enables power devices (PD)
discovery, classification, current limit, and other necessary functions. Safety features include short-circuit protection and
power-out auto-detection to PD.
2.2 Features
Power-over-Ethernet: Provides built-in 802.3af Power over Ethernet for network sites that need to run power over the
network cables. Each of the 10/100BASE-TX Ethernet ports on this switch provides up to 15.4 watts power for
connected wireless access points, IP phones and other PoE-supported devices, enabling them to be deployed at
difficult places such as on high walls and ceilings, where AC power outlets are not readily available.
QoS: Supports Quality of Service by the IEEE 802.1P standard. There are four priority queues enabling users to run
bandwidth-sensitive applications such as streaming multimedia and VoIP in network.
Spanning Tree: Supports IEEE 802.1D, IEEE 802.1w (RSTP: Rapid Spanning Tree Protocol) standards to prevent
network loops that could cause a broadcast storm.
VLAN: Supports Port-based VLAN and IEEE802.1Q Tag VLAN. Also supports 256 active VLANs and VLAN ID 1–
4094.
Port Trunking: Supports static port trunking and port trunking with IEEE 802.3ad LACP.
IGMP Snooping: Establishes the multicast groups to forward the multicast packet to the member ports, and avoids
wasting the bandwidth while IP multicast packets are running over the network.
Security: Support MAC Address and TCP/UDP filtering to prevent unknown users or un-authorized actions connected
to network.
