This review is from: Cisco SD2008 8-port 10/100/1000 Gigabit SwitchSignifiant changes have occurred over the life of this switch. Version 1 had an internal fan and was quite noisy, albeit cool running. Version 2 & 2.1 eliminated the fan. However capacitor C251, sitting next to an internal heatsink is prone to failure after 6 - 8 months, resulting in dropped packets and link connections. Version 3.0 has solved this problem with a complete re-layout of the printed circuit board (PCB), with a redesign of the power/voltage regulation. The new version, still fanless, runs MUCH cooler than version 2.1....
This review is from: Cisco SD2008 8-port 10/100/1000 Gigabit SwitchBought this switch and received the 2.1 version which is black. It is fanless or at least if it does have fans I don't hear them. Tested it and performance is good getting almost 1Gbit under all conditions (hard disks and other hardware being the limiting factor). Also tested it with jumbo frames and worked OK. Overall good buy, great speed with jumbo frame support at a nice price.Edit: After almost a year, now the swith will no longer negotiate gigabit and only works OK at 100Mbit. This seems to be a widespread problem with version 2.1. And Linksys seems to be slow replacing or repairing these units under their lifetime warranty. Would suggest getting another switch....
This review is from: Cisco SD2008 8-port 10/100/1000 Gigabit SwitchI have bought both the old version of the Linksys SD2008 about 2 years ago when first released and everyone is right - Loud, and unacceptable when sitting on a desk next to you. I am lucky that I built a server and placed it and all networking items in basement so it did not bother me. I did hear it when I went into basement thought. The fan started really getting loud about 3 months ago and it just died in the past week but switch is still going strong. I wanted to see it the Version 2.1 was any better than the 1.0 that I currently have. I have not switched over yet because I am waiting for other new parts but I did plug in new switch and well what do you know. TADA. No fan sounds. I dont think the newer version even have a fan in it. Its slightly better looking than original because front bezel is black instead of grey. I like that fact that the plugs are in the back compared to Netgears switches which plug into the front(which can make an unsightly mess with a lot of plugs) I have used Linksys products for many years now. With Cisco, they seem to get better every year. Give the newer 2.1 switch a try. You won't be dissappointed....
