Switching is a cost-effective way of increasing the total network capacity available to users on a LAN. If an Ethernet network begins to display symptoms of congestion, low throughput, slow response times, and high rates of collision, installing a switch to a network can preserve much or all of the existing network's cabling and workstation interface card infrastructure while still greatly enhancing the throughput for users.
VLAN. Cost Reduction: VLANs can be used to create multiple broadcast domains, thus eliminating the need of expensive routers. Port-based (or port-group) VLAN is the common method of implementing a VLAN, and is the one supplied in the Switch.
The front panel LEDs provides instant status feedback and simplifies monitoring and troubleshooting tasks. LED indicators of the Switch Power When the Power LED light is on, the Switch is receiving power. When the Power LED light is off, the power cord is improperly connected.
100Mbps When the LED light is on, the respective port is connected to a 100Mbps Ethernet network. When the LED light is off, the respective port is connected to a 10Mbps Ethernet network, or no link. Ports 25 & 26 Status LEDs Link/Act When the LED lights on, the respective port is connected to a 10/100/1000Mbps Ethernet network.
Rack Mounting The DES-1226G can be mounted in an EIA standard-size, 19-inch rack, which can be placed in a wiring closet with other equipment. Attach the mounting brackets to both sides of the Switch (one at each side), and secure them with the provided screws.
AC Power The DES-1226G can be used with AC power supply 100~240V AC, 50~60 Hz. The power switch is located at the rear of the unit adjacent to the AC power connector and the system fan. The Switch’s power supply will adjust to the local power source automatically and may be turned on without having any or all LAN segment cables connected.
Discovery List This is the list where you can discover all the D-Link Web-Smart devices in the entire network By clicking on the “Discovery” button, you can list all the Web-Smart devices in the discovery list.
Note: In order to receive Trap information, the Switch has to be configured with Trap IP and Trap Events in Web browser, available in the Trap Setting Menu (see Page 40 for details). Add Item: To manually add a device to the Monitor List, enter the IP Address of the device that you want to monitor.
Firmware Upgrade: When the device has a new function, there will be a new firmware to update the device. You can use this function to upgrade the firmware. Web Access: Double click the device in the Monitor List or select a device in the Monitor List and press the “Web Access” button to access the device in the Web browser.
Configuring the Switch The DES-1226G has a Web GUI interface for smart switch configuration. The Switch can be configured through the Web browser. A network administrator can manage, control, and monitor the Switch from the local LAN. This section indicates how to configure the Switch to enable its smart...
Flow Control: This setting determines whether or not the Switch will be handling flow control. Set FlowCtrl to Enable to avoid data transfer overflow. It is set to Disable when there is either no flow control or other hardware/software management.
Port Mirroring is a method of monitoring network traffic that forwards a copy of each incoming and/or outgoing packet from one port of a network switch to another port where the packet can be studied. It enables the manager to keep close track of switch performance and alter it if necessary.
Device Status Click on the “Status” to present the device status on this screen. It will display the System Status, Port Status, VLAN Status, Trunk Status, and Mirror Status. Press “Refresh” when you need to renew the posted information. System Setting The System Setting includes the System name, Location name, Login Timeout, IP Address, Subnet Mask, and Gateway.
Password is the invaluable tool used to secure Web Management Switch. Use this function to change the password. If you forget the password, press the “Reset” button in the rear panel of the Switch. The current settings, including VLAN, Port Setting… etc., will be lost and the Switch will restore to the default setting.
