Objective

Green Ethernet is a feature that reduces energy consumption on the switch. This way, the switch is more environmentally friendly, and your costs to run the switch are reduced.

This article explains how to configure Green Ethernet on the 200/300 Series Managed Switch.

Applicable Devices

• SF/SG 200 and SF/SG 300 Series Managed Switches

Software Version

• v1.2.7.76

Enable Global Green Ethernet

This section explains how to enable Green Ethernet on all the interfaces of the 200/300 Series Managed Switches.

Step 1. Log in to the web configuration utility and choose Port Management > Green Ethernet > Properties. The Properties page opens:

Step 2. In the Energy Detect Mode field, check the Enable check box to enable energy detect mode on an inactive link. For inactive links, this mode changes these links to inactive mode, but still maintains the administrative status of the port to Up.  This action reduces the power consumption of the switch.

Step 3. In the Short Reach field, check the Enable check box to enable Short Reach. This feature saves power on short length cables. After the cable length is analyzed, the power usage is adjusted.

Note: The Power Savings field displays the energy saved with Green Ethernet enabled.

Note: The Cumulative Energy Saved field displays the amount of energy saved since the last time the switch was rebooted.

Step 4. (Optional) In the Port LEDs field, to reduce power consumption, uncheck the Enable check box to disable LED activity on a interface.

Step 5. Click Apply to save your configuration.

Note: After this configuration, the network is temporally disconnected.

Green Ethernet Port Settings

This section explains how to enable/disable Green Ethernet on a specific interface.

Note: The Global Green Ethernet configuration must be completed properly before the Green Ethernet Port configuration can have any effect.

Single Interface Configuration

This subsection explains how to enable/disable Green Ethernet on a single interface.

Step 1. Log in to the web configuration utility and choose Port Management > Green Ethernet > Port Settings. The Port Settings page opens:

Step 2. Click the radio button of the interface you wish to configure.

Step 3. Click Edit. The Edit Port Setting window appears.

Step 4. (Optional) In the Energy Detect field, check the Enable check box to enable this feature on the specific port. This feature moves inactive links to inactive mode in order to reduce power consumption and keeps the administrative status of the port as up.

Step 5. (Optional) In the Short Reach field, check the Enable check box to enable this feature on the specific port. This feature analyzes the length of the cable and applies the proper techniques to the link to reduce power consumption.

Step 6. Click Apply to save your configuration. The changes are made to the Port Setting Table:

Apply an Interface Configuration to Multiple Interfaces

This subsection explains how to apply a single interface configuration to multiple interfaces.

Step 1. Log in to the web configuration utility and choose Port Management > Green Ethernet > Port Settings. The Port Settings page opens.

Step 2. Click the radio button of the interface whose configuration you wish to apply to multiple interfaces.

Step 3. Click Copy Settings. The Copy Settings window appears.

Step 4. In the field provided, enter the interfaces to which you wish to apply the configuration of the previously clicked interface. You can enter each interface by number or interface name (For example: 1, 2, 3 or GE1, GE2, GE8) or you can enter a range of interfaces by number or by name (For example: 7-10 or GE7-GE10).

Step 5. Click Apply to save your configuration. The changes are shown in the Port Setting Table:
