CableDiagnosticsFunction

With the continuing drive to Home/SMB

adaptation, D-Link’s Cable Diagnostics function

enables users to eficiently detect the cable

userstodeterminewhethertheirRJ-45cables

are Gigabit capable or for troubleshooting

problems of cables, simply through the web-

based interface to check the test results.

D-Link’s next generation Gigabit web smart switch

series is available at an affordable price, which is

economical for the small and medium business. The

smart switches provide user friendly Web-Based

management for easy coniguration. With three

models to choose from DES-1228/1228P/1252, this

series provide lexible choices for different network

requirements. Typically, fans are a key energy

consumer. The DGS-1228 and 1252 comes with an

innovative fanless design for a 19” metal case. The

three models are housed in a new style rack-mount

metal case with easy-to-view front panel diagnostic

LEDs, and facilitate advance features that include:

• Twocombo10/100/1000BASE-TSFPconnections

• Networksecurity

• Traficsegmentation

• QoS

• Versatilemanagement

in network. These functions allow switches to work

They support 802.1X port-based authentication,

allowing network to be conigured with external

RADIUSservers.

VersatileManagement

The new generation of web smart switches provides

growing businesses simple and easy management

of their network using an intuitive SmartConsole

utility or a Web-Based management interface that

allows administrators to remotely control their

network down to the port level. The SmartConsole

easily allows customers to discover multiple D-

Link web smart switches with the same L2 network

segment connected to user’s local PC. With this

utility, users do not need to change the IP address

of PC and also provides easy initial setting of smart

switches. The switches with the same L2 network

segment connected to user’s local PC are displayed

on the screen for instant access. It allows extensive

switch coniguration setting, and basic coniguration

of discovered devices such as password change,

irmware upgrade.

Seamless Integration

The Ethernet web smart switches are designed and

focused to provide SMB users a complete control

over network. With Ethernet and Gigabit copper

ports capable of connecting to your existing Cat.5

twisted-pair cable, these switches eliminate the

need of a complex reconiguration process. Each

slots for lexible connection to a backbone or servers.

In addition, all ports support auto-negotiation of

MDI/MDIX crossover, so do away with cross over

cables or uplink ports and bring inexpensive and

easy connection to your desktop.

ExtensiveLayer2Features

Implemented as complete L2 feature, these switches

include features such as IGMP snooping, port

mirroring, Spanning Tree and port trunks. The IEEE
