Summary: I wish I had seen these reviews before buying. The switch stops working until it is cycled. This problem occurs sometimes once every few days to several times a day. Considering the price of the unit and information provided by other reviews, its not worth the time and effort getting an RMA, I'm just going to throw it out.
Summary: the damn switch drops connections after a while. it's like the connections are extremely slow. it took me some searching to find the cause was the switch. the replacement has the same problem, so it's the product which has the problem.
Summary: UPDATE: After some research I see that the DGS-1008D is sensitive to power and the new printer was on the same circuit. Moving the printer to another power outlet solved the reset. I would upgrade the rating if the D_link web site had some information about what is a pretty widely publicized problem. I have had this product for a couple of years and never had a problem.
Summary: I purchased two of these to be used in a clustered environment which means I can't have loss of connectivity. Both switches, after a few weeks, started to reset themselves. I replaced cables and still had the same problem. I RMA'd both and the replacements are the same. DO NOT BUY THEM you will be sorry if you do.
Switch resets, drops connection when printer cycles
5 days ago
Summary: I suffered from the same problem with this switch that others here have reported. I returned it to D-Link for a replacement, because they had NO RECORD of any customers having such a problem and NO IDEA what could cause it. When the replacement device arrived, I experienced the same problem--whenever I sent something to my network printer, the switch would reset, dropping all connections. I believe I've isolated this as a power spike issue.
Summary: This is not a good switch. I have this switch in a production environment and it died without warning a year after installation. I returned the product to D-Link and got a replacement but the replacement died two months later. Instead of returning it again, I will be getting a different brand switch. I will now be careful to avoid D-Link products.
Beware: Drops All Connection (Faulty AC/DC Power Unit)

Summary: DGS-1008D, P/N:BGS1008DA.C3, H/W Ver.:C3. This gigabit switch repeatedly drops all connection. This happened to two of the D-Link DGS-1008D switches that we've purchased, so may indicate a manufacturing problem. Resolved problem by replacing AC/DC power supply units with non-Linksys brand.
Summary: Switch periodically resets and drops connections. RMA'd first unit, and new unit does the same thing. No way to determine why it resets - extremely frustrating. D-Link Tech-support is no help and claims no knowledge of this apparently common problem --- no wonder they discontinued this product.
Summary: Bought one for the office on December 05. It does not work. Well, it does, but it goes on and off , dropping the conecction very offen. Users are complaining about the extra time it takes them to finish their job on the network. So I will have to buy another brand , as suggested by our IT advisor. I lost my money on this one.
Summary: Ich hatte drei DGS-1008D im Einsatz. Nein, bei mir waren es keine Probleme mit dem Netzteil. Das Problem war, dass die Switches irgendwann in zufälligen Abständen im Bereich von einigen Stunden bis Wochen "aufhingen". Das heisst, der Netzwerkwerkverkehr wurde extrem verlangsamt oder kam gar nicht mehr durch. Ein Reset durch Aus- und Wiedereinstecken des Netzteils löste das Problem dann - bis zum nächsten Auftreten.
