Poe Wireless Router

The 5-Port 10/100/1000 Gigabit Switch provides non-blocking, wire speed switching for your 10, 100, and 1000 megabit network clients. Drop this switch in place of your current workgroup hub or switch, and you can upgrade your high-requirement workstations to full Gigabit speeds as necessary, while continuing to service other clients at their current speeds. Or build your network from the ground up, with appropriate link speeds for each users requirements. Either way, its perfect for graphics, multimedia, and other applications that have to move large files across the network quickly. With the 5-Port 10/100/1000 Gigabit Switch, you can connect your existing 10/100 Ethernet network to a Gigabit server backbone without any additional equipment.

View larger Self-Regulating Features With the Cisco SD2005, you can upgrade your existing 10/100 Ethernet network to Gigabit speed without any additional equipment. Automatic medium dependent interface (MDI) and MDI crossover (MDI-X) detection on all ports ensures that the correct cable type is selected. Auto speed negotiation allows each port to independently and automatically negotiate for the best speed and half- or full-duplex mode. Address Learning and Aging is supported, as well as 802.3x flow control with head-of-line blocking prevention to optimize your network performance. Fast store-and-forward switching prevents damaged packets from being passed onto the network. Compact and Reliable The SD2005's no-fan design helps ensure silent switch operation, with a compact size provides multiple placement options. Cisco reliability and a limited lifetime warranty help provide peace of mind. What's in the Box Cisco SD2005 5-Port 10/100/1000 Gigabit Switch, power adapter, Quick Start guide, warranty.

Tan Real quickly, I'm a network administrator for one of the largest websites in the US, so I'm not clueless when it comes to these devices. Like all the positive reviewers here, I was very happy with this unit when I first bought it. Worked like a charm, fast, cheap - what more could I ask for? Well how about a unit that didn't go belly up due to Linksys cutting corners on parts? Apparently some versions of the SD2008 and SD2005 had fans, but they have been cut out. Now these little buggers overheat, and when they do, it can cause capacitors to go bad which basically kill it's ability to operate in gigabit mode. In fact, several of my computers (and I've tried all sorts of NICs/computer combos) just repeatedly drop connection in a neverending loop. Nice work Linksys. I've read on forums that many others have the exact same problem - usually takes months for it to show up. One guy actually tore his apart, and saw the blistered/bulging components that had overheated and replaced them (hope you're handy w/a soldering iron.) 15 of 15 people found the following review helpful. poor reliability / performance after only a few months of use. By goillini I work in systems/network support. Our department has bought 6 of these switches over the past year (not all in one purchase, but 1 at a time as needed). 3 out of the 6 have now failed as others have mentioned in their reviews. The switches worked great for the first few months, but suddenly failed. Post-failure, they provide a 'gigabit' link, but throughput is < 100 Kbps. If I could give this switch zero stars, I would. Don't waste your money on this switch. 17 of 18 people found the following review helpful. Low quality junk that will die on you By Jonathan Birge You'll get the switch, you'll love it and write a great review. Then in a few weeks or months it will start going flakey. Eventually it will die completely. You'll hate it. Do us all a favor and wait a few months before you a write a breathless review about how great this is, and you'll save a lot of people trouble. Cisco should be sued over the uniformly poor quality of these switches. Here's a hint: if a company like Cisco won't put their name front and center on a product, it's probably because they're cutting corners. LinkSys is the brand Cisco uses when they want to sell crap but don't want to tarnish their own image. Real IT people know the LinkSys is Cisco's code for "we really phoned in this one."
