Web-based User Interface
Web Pages
Chapter 1 Introduction
All software functions of the DWS-3160 Series switches can be managed, configured and monitored via the
embedded web-based (HTML) interface. Manage the Switch from remote stations anywhere on the network
through a standard browser. 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.
Chapter 2 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.

To configure switch ports:
1. Choose the port or sequential range of ports using the From Port and To Port drop-down menus.
2. Use the remaining drop-down menus to configure the parameters described below:
The fields that can be configured are described below:
Parameter Description
From Port / To Port
Use the drop-down menu to select the port range to be configured.
State
Toggle the State field to either enable or disable a given port or group of ports.
Speed/Duplex Toggle the Speed/Duplex field to select the speed and full-duplex/half-duplex state of the
port. Auto denotes auto-negotiation among 10, 100 and 1000 Mbps devices, in full- or
half-duplex (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

DWS-3160 Series Gigabit Ethernet Unified Switch Web UI Reference Guide
9
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.
Flow Control Displays the flow control scheme used for the various port configurations. Ports
configured for full-duplex use 802.3x flow control, half-duplex ports use backpressure
flow control, and Auto ports use an automatic selection of the two. The default is
Disabled.
Address Learning Enable or disable MAC address learning for the selected ports. When Enabled,
destination and source MAC addresses are automatically listed in the forwarding table.
When address learning is Disabled, MAC addresses must be manually entered into the
forwarding table. This is sometimes done for reasons of security or efficiency. See the
section on Forwarding/Filtering for information on entering MAC addresses into the
forwarding table. The default setting is Enabled.
MDIX Auto - Select auto for auto sensing of the optimal type of cabling.
Normal - Select normal for normal cabling. If set to normal state, the port is in MDI mode
and can be connected to a PC NIC using a straight-through cable or a port (in MDI
mode) on another switch through a cross-over cable.

PoE
The DWS-3160-24PC switches support Power over Ethernet (PoE) as defined by the IEEE 802.3af and 802.3at. All
ports can support PoE up to 30W. Ports 1-24 can supply about 48 VDC power to Powered Devices (PDs) over
Category 5 or Category 3 UTP Ethernet cables. The Switch follows the standard PSE (Power Sourcing Equipment)
pinout Alternative A, whereby power is sent out over pins 1, 2, 3 and 6. The Switches work with all D-Link 802.3af
capable devices.
The Switch 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.
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 15.4W 0 15.4W
1 4.0W 1 4.0W
2 7.0W 2 7.0W
3 15.4W 3 15.4W
User define 31.2W
To configure the PoE features on the Switch, click System 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 1W and 370W for the Switch in the Power Limit field.
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.
PoE System Settings
To view the following window, click System Configuration > PoE > PoE System Settings, as show below:

DWS-3160 Series Gigabit Ethernet Unified Switch Web UI Reference Guide

Figure 5-7 PoE System Settings window
The following parameters can be configured:
Parameter Description
Power Limit (37-
760)
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 760W The default setting is 760W.
Power Disconnect
Method 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 Next 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 high-priority and critical priority ports to power up.
Legacy PD
Use the drop-down menu to enable or disable detecting legacy PDs signal.
Click Apply to implement changes made.
PoE Port Settings
To view the following window, click System Configuration > PoE > PoE Port Settings, as show below:

DWS-3160 Series Gigabit Ethernet Unified Switch Web UI Reference Guide
13
Figure 5-8 PoE Port Settings window
The following parameters can be configured:
Parameter Description
From Port / To Port
Select a range of ports from the drop-down menus to be enabled or disabled for PoE.
State
Use the drop-down menu to enable or disable ports for PoE.
Time Range 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.
Priority Use the drop-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.
Power Limit 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
ranges;
Class 0 – 0.44~15.4W
Class 1 – 0.44~4.0W
Class 2 – 4~7.0W
Class 3 – 7~15.4W
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 – 35000mW
