Digital Cameras Photo Reviews of Cisco SD2008 8-port 10/100/1000 Gigabit SwitchCustomer Review: Small, silent, and fast Summary: 4 Stars
An 8-port Gigabit switch for only $82?!? I thought this was definitely worth a test drive. There is no fan inside this unit, so the reviewers that complained about fan noise must be talking about a different model (the label on the bottom of my unit says "SD2008 Version 2.1"). The Gb ports appear to run at a full speed. The 100/1000 auto speed sensing worked fine except in one situation (see below); I couldn't test at 10Mb because I don't have any 10Mb devices anymore. It's a small package with mounting holes on the back. I mounted mine on the wall near where all my cat 5 cables terminate. All in all I found this switch trivial to deploy and a great performer.
The only problem I encountered was with some older building wiring that only uses 2 pairs. That's good for running 10/100Mb, but 1Gb requires 4 pairs. I could connect a 100Mb device to the SD2008 just fine using 2 pairs, but when I tried to connect a gigabit laptop the link never activated. At least with some other switches in this situation, the laptop interface drops down to 100Mb and all is fine. I don't know the details of the IEEE auto speed negotiation specification well enough to know what's suppose to happen in this case, and so I don't know if this is really a problem I can blame on the SD2008. In my particular situation I just switched to a wireless link that's available and bypassed the problem altogether. Of course I could also have upgraded the wiring to 4 pairs as the standard calls for, but it was a long wiring run and the wireless link was already available.
Description of Cisco SD2008 8-port 10/100/1000 Gigabit SwitchMODEL- SD2008 VENDOR- LINKSYS FEATURES- 8-Port 10/100/1000 Gigabit Switch The 8-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 it is perfect for graphics multimedia and other applications that have to move large files across the network quickly. With the 8-Port 10/100/1000 Gigabit Switch you can connect your existing 10/100 Ethernet network to a Gigabit server backbone without any additional equipment. All ports have automatic MDI/ MDI-X crossover detection so you do not have to worry about the cable type. Each port independently and automatically negotiates for best speed and whether to run in 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 keep your high- speed clients from bogging down in lower-speed traffic. Fast store- and-forward switching prevents damaged packets from being passed on into the network. Includes Gigabit Switch AC power adapter Registration card and User guide. * Eight 10/100/1000Mbps half/full duplex switched ports. * Forwards and filters packets at non-blocking full wire speed. * All ports have auto speed negotiation and auto MDI/MDI-X crossover detection. * Linksys reliability and limited lifetime warranty. -- SPECIFICATIONs -- STANDARDs - IEEE 802.3 802.3u
