I've purchased several SLM2008 switches (the same thing as the SD2008, but with an integrated web management interface) to be used at my workplace. In 6 months, I had 5 of 8 fail. They would stop routing packets, and when reset, they would not respond at all. All of them seem to run pretty warm. Even Linksys' 48-port switches seem to run pretty warm, and have intermittent connection issues. There weren't any issues in getting RMAs to return the little 8-port switches, but i noticed that the replacements I was shipped are the same version. I expect I'll be going through this again.
