Product Description

From the Manufacturer

From the Manufacturer The Cisco SD2008 8-Port Gigabit Switch provides nonblocking, wire-speed switching for 10-, 100-, and 1000 megabit (Mb) network clients. Use this switch to quickly share and transfer data, voice, and video across your network. You can connect up to 8 network devices such as computers, printers, and access points to create a small business network. The Cisco SD2008 is ideal for small businesses needing an affordable, easy to use switch that you can install yourself. You can connect your existing 10/100 Ethernet network to a Gigabit server backbone without any additional equipment. Or you can build your network from the ground up. Simply plug in your equipment and the switch will determine the appropriate speed for each device and user.



Cisco SD2008 8-port Gigabit Switch


8 Ports of Gigabit Ethernet to support high bandwidth applications


Gigabit Performance
The Cisco SD2008 provides up to Gigabit Ethernet speeds to deliver high speed connectivity to support bandwidth-intensive applications. Use it to replace your network hub or Fast Ethernet switch to maximize the performance of your applications. Each device you connect to the SD2008 can tap into transfer speeds of up to a gigabit per second. It's perfect for graphics, multimedia, and other applications that have to quickly move large files across the network. With this switch you get immediate file transfers, eliminating slow or sluggish network experiences and alleviating network bottlenecks.


Easy Set Up and Compact size
There's no software to configure – just plug in your Ethernet cables, connect a power cord, and go. All ports have automatic medium dependent interface (MDI) and MDI crossover (MDI-X) cable detection, so you don't have to worry about the cable type. Each port independently and automatically negotiates for best speed and determines whether to run in half- or full-duplex mode. The compact size makes it ideal for areas with limited space, such as your desktop and it comes with a wall mount kit so you can install it on a wall or under a desk.

Consistent Network Performance & Reliability
Integrated features like advanced store-and-forward packet switching and auto partitioning help ensure that the quality of the data passing through the switch is consistent and optimized. Address Learning and Aging are 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 to the network. World-famous Cisco reliability and a limited lifetime warranty give you peace of mind

Customer Questions & Answers

Customer Reviews

I have a fanless SD2008 that has failed after a period of about one year.
C. Riley
Simple testing of large file data transfer rates would have detected this issue before this green apple hit the market.
P. Chesnut
Compared to a Cisco 10/100 eight port microswitch, the Linksys gigabit switch was a little more than 5 times faster.

Signifiant 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.

Bought 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.

I 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.

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.

(Original Review): Geez, the unbelievable fan noise! It really is, as another reviewer put it, as loud as a 10-year-old PC. I'd actually put it as loud as a 20-year-old PC!

(Two Weeks Later): Interestingly, the noise has subsided dramatically after several weeks of ownship. It's completely unobjectionable now. I don't know if the fan bearings have worn away some rough spots, or what, but it's quiet, and still very cool, temperature-wise.

(About 10 Months Later): It died, mysteriously, after about six months. I replaced it with the Linksys SD2005 (five ports), which is way quieter, even compared to the post-two-weeks-quieter noise of this one, and which has been working great. [Still working great as of 2008]

I bought one of these for home use to replace my old 10baseT hub. I plugged in the Linksys switch and, my god is it loud. It has two internal fans in its tiny case, spinning at high RPMs. It's as loud as a server or a ten year old PC.

Despite its tiny size, this box is not suitable for home or any other quiet environment. A machine room, sure, on a desk or in your music studio? Absolutely not.

I'm sending mine back and getting a fanless Netgear switch instead.

Hi Patrick,

Thank you for your comments! In response to feedback we received about the noise, we've addressed the issue by creating fanless designs in newer models of this switch-the SD2008T and SG100D-08.
