Seamless Integration

The switches offer Gigabit copper ports that are

capable of connecting to your existing Cat.5 twisted-

pair cables. This eliminates the need of a complex

re-conﬁ guration process. Each switch model of the

Gigabit series provides two or four combo SFP slots

to form a multi-level network structure consisting

of a high-speed backbone and centralized servers.

In addition, all the ports support auto-negotiation

and MDI/MDIX crossover function. So do away

with cross over cables or uplink ports and bring

inexpensive Gigabit connection to your desktop.

Extensive Layer 2 Features

The switches offer superior performance and

availability through features such as Jumbo Frames,

IGMP Snooping, Port Mirroring, Spanning Tree and

Port Trunking. IEEE 802.3x Flow Control allows your

servers to directly connect to the switch for fast,

reliable data transfer. The Gigabit ports provide

dedicated bandwidths for your desktops running at

2000Mbps full duplex, with minimum data transfer

loss.

Trafﬁ c Prioritization

802.1Q VLAN tagging prioritizes trafﬁ c, enhances

network security and performance while 802.1p

enables you to run bandwidth-sensitive applications

such as streaming multimedia and VoIP in network.

These functions allow switches to work seamlessly

in the network.

Cable Diagnostics

Gigabit networks use 8-wire CAT 5 RJ-45 cables.

However, networks in older buildings could still

be using 4-wire CAT 3/5 RJ-45 cables. The Cable

Diagnostics function assists you to effectively

detect the RJ-45 cable condition while migrating

from an existing network to a Gigabit-capable one,

and minimizing service calls during migration. Other

cable-related problems are, an RJ-45 cable with an

open circuit (a lack of continuity between the pins

at each end of an Ethernet cable or a disconnected

cable) or a short circuit between two or more

conductors.

Network Security

The switches provide MAC address ﬁ lters screen,

for easy access to the network. They support 802.1X

port-based authentication, allowing the network

to be conﬁ gured with external RADIUS servers.

Enhance your network security with the Asymmetric

VLAN feature. With this feature, you can segregate

ports into different virtual LAN groups to enhance

security and prevent data leaks. This feature also

increases the efﬁ ciency of sharing resources such

as servers or gateway devices.

D-Link Safeguard Engine identiﬁ es and prioritizes

“CPU interested” packets to prevent malicious

trafﬁ c from interrupting normal network ﬂ ows and

protects switch operation.

Versatile Management

The switches’ web-based SmartConsole Utility is as

easy to use as surﬁ ng the web. The utility includes

useful features that automatically discover and

display all web smart switches on the same L2

network segment connected to a local PC. The web-

based GUI allows for easy access to a switch from

anywhere without having to remember IP addresses

or subnets. The GUI also includes a wizard that

allows you to pre-conﬁ gure basic functions such as

passwords, system information and SNMP settings.

Users can also use the built-in MIB browser to poll

the switches for information about their status and

send trap messages of abnormal events. The MIB

browser allows users to integrate the switches with

the third-party devices for management in an SNMP

environment.
