1. Introduction 

1-1. Overview of 24-Port GbE Web Smart Switch 

The 24-port Gigabit Web Smart Switch is a standard switch that meets all 

IEEE 802.3/u/x/z Gigabit, Fast Ethernet specifications. The switch has 20 
10/100/1000Mbps TP ports and 4 Gigabit TP/SFP transceiver slots; it supports http 
and SNMP interface for switch management. The network administrator can logon 
the switch to monitor, configure and control each port’s activity. In addition, the 
switch implements the QoS (Quality of Service), VLAN, and Trunking. It is suitable 
for office application. 

Others the switch  increase support the Power saving for reduce the power 

consumption with "ActiPHY Power Management" and "PerfectReach Power 
Management" two technique.It could efficient saving the switch power with auto 
detect the client idle and cable length to provide different power. 

In this switch, Port 21, 22, 23, 24 includes two types of media --- TP and SFP 

Fiber (LC, BiDi-SC…); this port supports 10/100/1000Mbps TP or 1000Mbps SFP 
Fiber with auto-detected function. 1000Mbps SFP Fiber transceiver is used for high-
speed connection expansion. 

 

1000Mbps LC, Multi-Mode, SFP Fiber transceiver 

 

1000Mbps LC, 10km, SFP Fiber transceiver 

 

1000Mbps LC, 30km, SFP Fiber transceiver  

 

1000Mbps LC, 50km, SFP Fiber transceiver 

 

1000Mbps BiDi-SC, 20km, 1550nm SFP Fiber WDM transceiver 

 

1000Mbps BiDi-SC, 20km, 1310nm SFP Fiber WDM transceiver 

 

10/100/1000Mbps TP is a standard Ethernet port that meets all IEEE 

802.3/u/x/z Gigabit, Fast Ethernet specifications. 1000Mbps SFP Fiber transceiver 
is a Gigabit Ethernet port that fully complies with all IEEE 802.3z and 1000Base-
SX/LX standards.  

1000Mbps Single Fiber WDM (BiDi) transceiver is designed with an optic 

Wavelength Division Multiplexing (WDM) technology that transports bi-directional 
full duplex signal over a single fiber simultaneously.  

 

• 

Key Features in the Device 

QoS: 

The 

switch

 offers powerful QoS function. This function supports 802.1p 

VLAN tag priority and DSCP on Layer 3 of network framework.  

VLAN: 

Supports Port-based VLAN, IEEE802.1Q Tag VLAN. And supports 24 active 
VLANs and VLAN ID 1~4094.
