Installation the D-Link DGS-2205 Green Switch

1.Before You Connect to the Network

The site where you install the Switch may greatly affect its performance. Please follow these guidelines for setting up the Switch.

• Install the Switch on a sturdy, level surface that can support at least 3 kg (6.6 lbs.) of weight. Do not place heavy objects on the Switch.

• The power outlet should be within 1.82 meters (6 feet) of the Switch.

• Visually inspect the power cord and see that it is fully secured to the AC power port.

• Make sure that there is adequate space for proper heat dissipation from and adequate ventilation around the Switch. Leave at least 10 cm (4 inches) of space at the front and rear of the Switch for ventilation.

• Install the Switch in a fairly cool and dry place for the acceptable temperature and humidity operating ranges.

• Install the Switch in a site free from strong electromagnetic field generators (such as motors), vibration, dust, and direct exposure to sunlight.

• When installing the Switch on a level surface, attach the rubber feet to the bottom of the device. The rubber feet cushion the Switch, protect the casing from scratches, and prevent it from scratching other surfaces.

Mounting the Switch on the Wall

The DGS-2205 can also be mounted on a wall. Two mounting slots are provided on the bottom of the switch for this purpose. Please make sure that the front panel is exposed in order to view the LEDs. Please refer to the illustration below:

1. Mount the Nylon screw anchors into a cement wall.
2. Drive the T3 x 15L screws into the Nylon screw anchors.
3. Hook the mounting holes of the switch back on the screws.

Connecting the Switch

■DGS-2205 to End Node

End nodes include PCs outfitted with a 10, 100, or 1000 Mbps RJ-45 Ethernet Network Interface Card (NIC) and most routers. An end node can be connected to the Switch via a twisted-pair Category 3, 4, 5, or 5e UTP/STP cable. The end node can be connected to any of the ports of the Switch.

The Link/Act LEDs for each UTP port light green when the link is valid. The LED over the port label indicates a port speed of either 10/100 Mbps or 1000Mbps. A blinking LED on the bottom indicates packet activity on that port.

■Hub/Switch to DGS-2205

These connections can be accomplished in a number of ways using a standard Ethernet cable.

• A 10BASE-T hub or switch can be connected to the Switch via a twisted-pair Category 3, 4, 5, or 5e UTP/STP cable.
• A 100BASE-T hub or switch can be connected to the Switch via a twisted -pair Category 5 UTP/STP cable.
• A 1000BASE-T switch can be connected to the Switch via a twisted -pair Category 5e or better UTP/STP cable.

■Connecting To Network Backbone or Server

Any of the five Gigabit Ethernet ports are ideal for uplinking to a network backbone or network server.

Troubleshooting

●Why can´t I share my Internet connection to multiple computers when using my D-Link DGS-2205 switch?

If you are connecting directly to a Cable or DSL modem, you will need a router to “share” your Internet connection or a computer using ICS (Internet Connection Sharing) or Proxy. Switches and hubs do not allow you to share a single IP address to multiple computers.

Another alternative is to contact your ISP and purchase extra IP addresses for each additional computer.

●Does the DGS-2205 switch have an uplink port?

The DGS-2205 has Auto-MDI ports which automatically sense the type of cable being used (e.g. Crossover or Straight-through) and adjust themselves accordingly to pass data over the network.

●What is the maximum length of Category 3, 4 or 5 twisted pair cable that can be used between the DGS-2205 and other devices such as routers, switches, computers, etc.?

The maximum length of Category 3, 4 or 5 twisted pair cable that can be used between computers and other devices on a network is 100 meters or about 328 feet. Keep in mind that this is a theoretical limit. Usually, you will want to keep the distance between devices well below the limit.

D-Link’s DGS-2208 8-port Switch is greener than ever and can save you both power and money.

The DGS-2208 provides three key benefits through its cutting edge, innovative D-Link Green eco-friendly technology:

  • Reduces power consumption & creates less heat
  • Extended product life
  • Reduces operating costs

dlink-dgs-2208

Power Savings by Cable Length

D-Link Green verified switches have the ability to analyze the length of any Ethernet cable connected to them for adjustment of power usage accordingly. Shorter lengths require less power.

Power Savings by Number of Connected Ports and Link Status

Computers do not require Internet access all the time; neither do switches utilize all ports at all times. When a computer or network equipment is shut down, switches often remain on and continue to consume considerable amounts of power. With D-Link Green Technology, D-Link switches can automatically detect link status and reduce power usage of ports that are idle. Computers or any connecting parties set to standby mode (not power off), however, will not provide significant power savings.

Overall Power Savings Per Day

For a traditional switch, power consumption remains constant even when the ports are not in use. In a standard workday scenario where PCs are used for 10 hours a day and powered off 14 hours a day, and connected to the switch using 20 meter cables, D-Link Green Technology can save up to 40%* power used for each system.

It’s Geektime DGS-2208 reviews

Our first product review for Its Geek Time is this nifty gigabit network switch brought to you by D-Link. For years D-link has taken a back seat to bigger companies like Linksys and Netgear for home network equipment. In recent years D-Link has increased their product quality and can contend with the big guys on an equal footing. This switch is a product that proves that.

The first thing to note about this switch is it is a gigabit switch with 8 ports for less than $50. A comparable Netgear or Linksys switch will cost you much more money. The other important thing about its speed is you can connect 10/100 devices to it and not lose gigabit connectivity to gigabit enabled devices that are also connected to it. On older gigabit switches, the switch would throttle down to the slowest device connected to it.

Another new feature on this switch is its power saving feature. Ports that are not in use are turned off so the device uses less power over all. This turns into cost benefits from less electricity usage, less heat generated by the product, and a longer life span due to less wear and tear. In an age where electricity prices are at an all-time high, anything that saves power is a welcome addition to many homes and offices.

In conclusion, this switch is recommended for any home network or small office network that is on a budget and wants gigabit functionality.
