24/48-Port Ethernet Switch

Web Smart Switch

  

     

     

 

 

  

-Link's next generation Web Smart Ethernet switch series blends plug-and-play simplicity with

exceptional value and reliability for small and medium-sized business (SMB) networking. Each switch 
is housed in a new style rack-mount metal case with easy-to-view front-panel diagnostic LEDs, and 
provides advance features including 4 Gigabit uplinks, combo 1000BASE-T/SFP, network security, 
traffic segmentation, QoS and versatile management.

Choices of 24 and 48 ports. Two port densities are available for selection: 24 Ethernet ports and 48 
Ethernet ports. Supporting auto-detection of MDI/MDIX, these switches bring inexpensive and easy 
Ethernet connection to the desktops. Each switch provides 4 Gigabit uplinks connection to a Gigabit 
backbone or servers.

Power Over Ethernet Option. Switch model DES-1228P provides built-in 802.3af Power over Ethernet 
for network sites needing to run power over the network cables. Each the 24 10/100BASE-TX
Ethernet ports of this switch provides up to 15.4 watts power for connected wireless access points, IP 
phones and other PoE-supported devices, allowing them to be deployed at difficult places such as on 
high walls and ceilings, where AC power outlets are not readily available.

Extensive Layer 2 Features. Implemented as complete L2 devices, these switches include functions 
such as IGMP snooping, port mirroring, Spanning Tree, port trunks and 802.3x Flow Control to 
enhance performance and network resiliency.

Traffic Segmentation and QoS. The switches support 802.1Q VLAN Tagging for traffic segmentation 
by groups to enhance network security and performance. They also support 802.1p Priority Queues, 
enabling users to run bandwidth-sensitive applications such as streaming multimedia and VoIP on the 
network. These functions allow the switches to work seamlessly with managed VLAN and 802.1p 
traffic on the network.

Network Security. The switches provide MAC address filters screen access to the network. They 
support 802.1x port-based authentication, allowing the network to be configured with external 
RADIUS servers. Additional features like D-Link Safeguard Engine protect the switches against traffic 
flooding caused by virus/worm outbreaks.

Versatile Management. Switch configuration and management is through the SmartConsole Utility or 
a web-based GUI. SmartConsole is an easy way to access the switch from a local PC; users do not 
have to type in any IP address or subnet, and all switches connected on the network are displayed on 
the screen for instant access. The web-based GUI allows switch access from any location on the 
network or from a remote site, using a web-browser. It allows extensive switch configuration setting, 
which can be backed up for duplication in other switches. 

In addition, users can also use the built-in MIB to poll the switches for information about their status 
and send traps of abnormal events. MIB support allows users to integrate the switches with other 
third-party devices for management in an SNMP environment.
