D-Link Announces Green Switches

[Polaris573]

D-link has announced Ethernet desktop switches that, it claims, use up to 44 percent less power than existing 5-port switches. It said it was the first company to bring such green Ethernet switches to the market. The power saving is accomplished in two ways. First, the new switches measure when PCs connected to them are turned off and then power down into standby mode. Secondly, they analyze cable lengths and can adjust power usage for different cable lengths accordingly. Most existing switches are powered up to support 100m cable lengths all the time, but many small systems use only 5-10m of cable. The IEEE standards body has an energy-efficient Ethernet study group, known as 802.3 A ratified standard is not expected for a couple of years or more and D-Link has introduced its products well before this. D-Link does not appear to be involved with this standards effort. D-Link will deliver Green Ethernet switches across its range of desktop, smart and xStack managed switches. All of the company's sub-24 port desktop switches will be green by the end of 2007. The smart and managed switches will evolve to Green Ethernet products through 2008.

Thank god they're cutting power. Means they're also dropping heat...I can't believe how hot our netgear wireless router gets. I hope all routers follow suit.

Thank god they're cutting power. Means they're also dropping heat...I can't believe how hot our netgear wireless router gets. I hope all routers follow suit.

In our small network, we have:

1./ Modem
2./ Main router/gateway
3./ Second router
4./ Network bridge (2 devices needed)
5./ Router at far side of bridge
6./ Printer "hub" 1
7./ Printer "hub" 2
8./ Wireless access point
9./ Two gigabit switches connecting PCs and Servers

= 11 devices just for keeping the network up

Since each device has a 12V 1.2A brick, that's 11x25W. = 275W

I'd be delighted for an industry shift toward lower powered network infrastructure... but too late for me. :-(

PS. I guess all these devices keep our winter heating bills down... Unfortunately, makes the place hotter in the summer. LOL

Here is a question...how much power can an ethernet router/switch consume? Are are they talking about the big server switches?

First 5 port switches and then 24 port switches by the end of the year.
