Product Description

From the Manufacturer

From the Manufacturer The first Green Ethernet technology on the market the DGS-2205 features innovative technology.

• Reduces power consumption & creates less heat
• Extended product life
• Reduces Operating Costs

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 shutdown, switches often remain on and continue to consume considerable amount of power. With Green Ethernet 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.
 
Power Savings by Cable Length
The Green Ethernet 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.
 
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's Green Ethernet can save up to 27%* power used for each system.
 
Note: Switch uses switching power adapter. The cable length which PCs are connected to switch is 20m cables. The D-Link DGS-2205 is a 5-port 10/100/1000Mbps Gigabit Switch that delivers power, performance, and reliability in one cost-effective, space-saving design. Increase the speed of your network server and backbone connections, or make Gigabit to the desktop a reality. Power users in the home, office, workgroup, or creative production environment can now move large, bandwidth-intensive files faster. Transfer graphics, CGI, CAD, or multimedia files across the network instantly. Power-Packed
The D-Link DGS-2205 10/100/1000 Mbps Gigabit Switch features a non-blocking switching architecture that filters and forwards packets at full wire-speed for maximum throughput. An 8,000 MAC address table provides scalability for even the largest networks. Address learning and aging, 802.3x Flow Control for full duplex mode, and back pressure flow control for half-duplex mode alleviates traffic congestion and ensures reliable data transmission. Designed using industry standards, it is compatible with virtually all 10, 100, and 1000Mbps Ethernet devices and other vendor equipment. The D-Link DGS-2205 10/100/1000 Mbps Gigabit Switch protects your existing network investments while providing you with a straightforward migration path to faster Gigabit speeds. Easy to use
The auto features of this gigabit switch make installation plug and play and hassle-free. No configuring is required. Auto MDI/MDI-X crossover on all ports eliminate the need for crossover cables or uplink ports. Auto-negotiation on each port senses the link speed of a network device (either 10, 100, or 1000 Mbps) and intelligently adjusts for compatibility and optimal performance. It also features diagnostic LEDs which display status and activity, allowing you to quickly detect and correct problems on the network. * Power savings may vary depending on products used. Maximum power savings when compared to a D-Link conventional switch. Uses up to 44% less energy when connected devices are powered down and up to 27% less energy when connected devices are used 10 hours and powered down 14 hours over a 24-hour period, when connected via 20 meter Ethernet cables. Green Ethernet features available on hardware version B1 or later.

5.0 out of 5 stars Very good throughput for a small footprint, February 1, 2008

My model is the DGS-2205 with the 5V power adapter. Like a previous reviewer, I noticed that I wasn't getting anywhere near gigabit speeds to my LaCie Ethernet Raid device. Well, that's because the LaCie Ethernet Raid Device is a slow pig.

After connecting my Mac Book Pro and my Mac Pro to the switch, I started offloading data to the Mac Pro.

Sustained throughput was 320 megabits per second with long bursts up to 720 megabits per second. At this point, the hard drive on the Macbook Pro was the bottleneck. Normally, I don't care for D-link products, but this little switch is quite the gem.

I've also noticed no noise from the unit, even when transferring large amounts of data at near wire speed.

Works Great, Clear light indicators, good product.
There are 2 versions of this on the market. There is a early version of 7V DC and the new rev 5V DC. I would take the 5V units only.

A good switch should require no real thought to install. You plug in, connect cat5e cables, and you're done. After that, it should work invisibly, giving you good throughput and no concerns whatsoever.

This one does that. If you need a modest-cost 5-port gigabit switch, I can recommend this one without reservation.

Notes: (1) If you don't need gigabit, you can get 100mb equipment pretty cheap right now. (2) Keep in mind that you use 1 port in a switch for the incoming cable, so a 5-port gives you connection to 4 devices, 8-port allows for 7 devices, etc. (Yeah, I know, it's dumb, but that's the way techies think.) (3) If you think you might need a couple more ports later, then definitely get the 8-port switch, since you don't pay that much more for the extra ports.

If you're concerned about expectations for the brand -- I am generally pretty happy with DLink products. I certainly haven't had any breaking right after 1 year of use, as I have had for some other brands.
