The SMC8508T is a 8-port 10/100/1000 Gigabit switch that provides non-blocking, wire-speed switching for your 10, 100, and 1000 megabit network clients. With the SMC8508T, you can connect your existing 10/100 Ethernet network to a Gigabit server backbone without any additional equipment. You can replace your current workgroup hub or switch with the SMC8508T and instantly upgrade your high-requirement workstations to full Gigabit speeds, while continuing to service other clients at their current speeds. Or you can build your network from the ground up, with appropriate link speeds for each user's requirements. Either way, the SMC8508T, and its jumbo frame support, is perfect for graphics, multimedia, and other applications that require you to move large files across the network quickly. All ports have automatic MDI/MDI-X crossover detection, so you don't have to worry about cable types. Each port independently and automatically negotiates for best speed and whether to run in half- or full-duplex mode. Limited Life Time Warranty. 24/7 Technical Support 1-800-SMC-4YOU.
Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
Very few gigabit switches support jumbo frames. Very few people care. If you do care, you'll be pleased to know that this switch supports up to 9 KB MTU. However, all machines connected to this switch (directly, or via other layer 2 switches) must be configured to use the same MTU. So, most people won't & shouldn't bother with it.
Other points in favor of this switch include: seems well-constructed (metal chassis), includes rackmount brackets, is fanless, and seems to run relatively cool (though I'm not taxing it, by any means).
I'm pleased - so far it's everything I hoped! As my title suggests, I looked at reviews & datasheets of nearly a dozen 8-port GigE switches, before selecting this one. This is a great deal!!
In building out a DC powered rack,we were looking specifically for a 12VDC powered rack-mountable switch. The unit arrived as a 9V, with attached documentation "included power supply as required" in the specification. So we threw it out, and have ordered a different unit. For a home user, it would make no difference... but if a unit is advertised with power supply specs, then I expect to receive same.
It works well as a standard gigabit ethernet switch, but if you are looking for jumbo frame support you really should look elsewhere. It works well as some other reviewers on other sites have said up to around 6k packets, after which packet loss starts to increase. Additionally you can find analysis of this switch online showing blocking after about 4.5k packets, with a performance cliff around 7k packets. This is exactly what I saw, and would cause my fairly expensive Intel e1000 NIC to reset its own port back to 100 mbps. According to what I've found online there are actually two models, so it could be this problem is only with the original model (which I purchased in 2007). Anyway, I replaced this switch with a managed gigabit dlink switch and now have no problems. Anyway, it works well if all you want is regular gigabit, but stay away if you need reliable jumbo packets.
I received my SMC8508T 3/21/2005. I plugged it in and so far it works like a charm.. It has a metal case to dissipate heat and best of all its quiet (no fan). My home network is now running at Gigabit speed and file transfers are blazing fast.
I've had the switch for a few months and it works great. Rack mounting with the supplied ears was easy. I haven't played with the jumbo frames, so I can't comment on that but the gig speed is good enough for my soho application. My only real complaint (if you can even call it that) is I wish it was black instead of dark gray because it looks weird in the rack with all the other black parts and filler plates.

I agree with the others who posted after they encountered a problem with the product. This product is fabulous when it works, but if if goes dead on you, you are own your own. It worked great for a few months before it died. I tried to negotiate customer support with a very poor telephone connection to India, speaking with a person who understood little English. The U.S. tech support office could offer no help when I tried calling them later.
Since these routers are all the same, buy from a company with good tech support.
I've owned this switch for awhile. I originally bought it because it could do large block file transfers, but am now using it as the switch between my media center pc and the hdhomerun prime. Works really good. No issues with streaming video. Bought another one (same model) and couldn't be happier.
The title speaks for itself. Watch out for their lifetime limited warranty, it's good for about a year and a half. I guess that must be the lifetime of some kind of horsefly or something.
