1 Product Introduction
Thank you and congratulations on your purchase of D-Link EasySmart Switch Products.
D-Link's next generation EasySmart Ethernet switch series blends plug-and-play simplicity with exceptional
value and reliability for small and medium-sized business (SMB) networking. All models are housed in a new
style rack-mount metal case with easy-to-view front panel diagnostic LEDs.
The brand-new DGS-1100 series are born to be green by design of IEEE 802.3az Energy Efficient Ethernet
compliant (abbreviated as EEE) and D-Link Green Technologies. It allows significant power saving during
periods of low data activity. In most of use cases and environments, switches are idle in 90% or more of time.
While no traffic in a short period of time, ports on DGS-1100 switch get into power saving mode automatically.
Once if a packet is received, the switch wakes and works immediately. Connecting to EEE compliant devices,
such as PCs and servers, the network can save energy without compromising any performance. While
connecting to legacy devices which do not support IEEE 802.3az, D-Link Green Technologies can reduce
power consumption by detecting short cable and link-down devices.

This chapter introduces the management interface of D-Link EasySmart Switch.
Management Options
The D-Link EasySmart Switch can be managed through any port on the device by using the Web-based
Management or through any PC using the SmartConsole Utility.
Each switch must be assigned its own IP Address, which is used for communication with Web-Based
Management. The PC’s IP address should be in the same range as the switch. Each switch can allow only
one user to access the Web-Based Management at a time.
The PC should have an IP address in the same range as the switch. Each switch can allow one user to
access to the Web-Based Management at a time.
However, if you want to manage multiple D-Link EasySmart Switches, the SmartConsole Utility is a more
convenient choice. By using the SmartConsole Utility, you do not need to change the IP address of your PC
and it is easier to initialize multiple EasySmart Switches.
Please refer to the following installation instructions for the Web-based Management and the SmartConsole
Utility.
Using Web-based Management
After a successful physical installation, you can configure the Switch, monitor the network status, and display
statistics using a web browser.
