Chapter 1 Web-based Switch Configuration
Introduction
Login to the Web Manager
Web-based User Interface
Web Pages
Introduction
All software functions of the Switch can be managed, configured and monitored via the embedded web-based (HTML)
interface. The Switch can be managed from remote stations anywhere on the network through a standard browser
such as Firefox, Safari, or Microsoft Internet Explorer. The browser acts as a universal access tool and can
communicate directly with the Switch using the HTTP protocol.
The Web-based management module and the Console program (and Telnet) are different ways to access the same
internal switching software and configure it. Thus, all settings encountered in web-based management are the same as
those found in the console program.
Login to the Web Manager
To begin managing the Switch, simply run the browser installed on your computer and point it to the IP address you
have defined for the device. The URL in the address bar should read something like: http://123.123.123.123, where the
numbers 123 represent the IP address of the Switch.
NOTE: The factory default IP address is 10.90.90.90.
This opens the management module's user authentication window, as seen below.

Leave both the User Name field and the Password field blank and click OK. This will open the Web-based user
interface. The Switch management features available in the Web-based manager are explained below.
Web-based User Interface
The user interface provides access to various Switch configuration and management windows, allows you to view
performance statistics, and permits you to graphically monitor the system status.

port. Auto denotes auto-negotiation among 10, 100 and 1000 Mbps devices, in full- or halfduplex (except 1000 Mbps which is always full duplex). The Auto setting allows the port to
automatically determine the fastest settings the device the port is connected to can handle,
and then to use those settings. The other options are 10M Half, 10M Full, 100M Half, 100M
Full, 1000M Full_Master, 1000M Full_Slave, and 1000M Full. There is no automatic
adjustment of port settings with any option other than Auto.
The Switch allows the user to configure three types of gigabit connections; 1000M
Full_Master, 1000M Full_Slave, and 1000M Full. Gigabit connections only support full
duplex connections and take on certain characteristics that are different from the other
choices listed.
The 1000M Full_Master and 1000M Full_Slave parameters refer to connections running a
1000BASE-T cable for connection between the Switch port and other device capable of a
gigabit connection. The master setting (1000M Full_Master) will allow the port to advertise
capabilities related to duplex, speed and physical layer type. The master setting will also
determine the master and slave relationship between the two connected physical layers.
This relationship is necessary for establishing the timing control between the two physical
layers. The timing control is set on a master physical layer by a local source. The slave
setting (1000M Full_Slave) uses loop timing, where the timing comes from a data stream
received from the master. If one connection is set for 1000M Full_Master, the other side of
the connection must be set for 1000M Full_Slave. Any other configuration will result in a link
down status for both ports.

PoE
The DES-3528P/DES-3552P Switch supports Power over Ethernet (PoE) as defined by the IEEE 802.3af. Ports 1 to 8
can support PoE up to 30W. (DES-3528P) Ports 1 to 24/(DES-3552P) Ports 1 to 48 can supply about 48 VDC power to
Powered Devices (PDs) over Category 5 or Category 3 UTP Ethernet cables. The DES-3528P /DES-3552P follows the
standard PSE (Power Sourcing Equipment) pinout Alternative A, whereby power is sent out over pins 1, 2, 3 and 6.
The DES-3528P/3552P works with all D-Link 802.3af capable devices.
The DES-3528P/DES-3552P includes the following PoE features:
• Auto-discovery recognizes the connection of a PD (Powered Device) and automatically sends power to
it.
• The Auto-disable feature occurs under two conditions: firstly, if the total power consumption exceeds
the system power limit; and secondly, if the per port power consumption exceeds the per port power
limit.
• Active circuit protection automatically disables the port if there is a short. Other ports will remain active.
12
xStack® DES-3528/DES-3552 Series Layer 2 Stackable Fast Ethernet Manage d Switch Web UI Reference Guide
Based on 802.3af/at PDs receive power according to the following classification: PSE provides power according to the following classification:
Class Maximum power available to PD
Class Max power used by PSE
0 12.95W
1 3.84W
2 6.49W
3 12.95W
4 29.5W
To configure the PoE features on the DES-3528P/DES-3552P, click Configuration > PoE. The PoE System Settings
window is used to assign a power limit and power disconnect method for the whole PoE system. To configure the
Power Limit for the PoE system, enter a value between 37W and 370W for the DES-3528P/DES-3552P in the Powe r
Limit field. The default setting is 370W. When the total consumed power exceeds the power limit, the PoE controller
(located in the PSE) disconnects the power to prevent overloading the power supply.

Sets the limit of power to be used from the Switch’s power source to PoE ports. The user
may configure a Power Limit between 37W and 370W for the DES-3528P/DE S -3552P. The
default setting is 370W.
The PoE controller uses either Deny Next Port or Deny Low Priority Port to offset the power
limit being exceeded and keeps the Switch’s power at a usable level. Use the drop-down
menu to select a Power Disconnect Method. The default Power Disconnect Method is Deny
Next Port. Both Power Disconnection Methods are described below:
Deny Next Port - After the power limit has been exceeded, the next port attempting to power
up is denied, regardless of its priority. If Power Disconnection Method is set to Deny N ext
Port, the system cannot utilize out of its maximum power capacity. The maximum unused
watt is 19W.
Deny Low Priority Port - After the power limit has been exceeded, the next port attempting
to power up causes the port with the lowest priority to shut down so as to allow the highpriority and critical priority ports to power up.
Use the drop-down menu to enable or disable detecting legacy PDs signal.

Select a range of ports from the pull-down menus to be enabled or disabled for PoE.
Use the pull-down menu to enable or disable ports for PoE.
Select a range of the time to the port set as PoE. If Time Range is configured, the power
can only be supplied during the specified period of time.
Use the pull-down menu to select the priority of the PoE ports. Port priority determines the
priority which the system attempts to supply the power to the ports. There are three levels of
priority that can be selected, critical, high, and low. When multiple ports happen to have the
same level of priority, the port ID will be used to determine the priority. The lower port ID
has higher priority. The setting of priority will affect the order of supplying power. Whether
the disconnect method is set to deny low priority port, the priority of each port will be used
by the system to manage the supply of power to ports.
This function is used to configure the per-port power limit. If a port exceeds its power limit, it
will shut down.
Based on 802.3af/802.3at, there are different PD classes and power consumption range s;
Class 0 – 0.44~12.95W
Class 1 – 0.44~3.84W
Class 2 – 3.84~6.49W
Class 3 – 6.49~12.95W
Class 4 – 12.95W~29.5W (only ports 1~8)
The following is the power limit applied to the port for these five classes. For each class, the
power limit is a little more than the power consumption range for that class. This takes into
account any power loss on the cable. Thus, the following are the typical values;
Class 0 : 15400mW
Class 1 : 4000mW
Class 2 : 7000mW
Class 3 : 15400mW
User define: 30000mW (15400~30000 only applies to ports 1 - 8)
As well as these four pre-defined settings, users can directly specify any value ranging from
1000mW to 30000mW on DES-3528P/DES-3552P ports 1 to 8 and 1000mW - 15400mW
on DES-3528P ports 9 to 24/DES-3552P ports 9 to 48.
NOTE: DES-3528P/DES-3552P ports 1 to 8 can support PoE up to 30W by configuring the
PoE port user define value, also all ports can support 802.3af (1000 - 15400mW).
