I have a problem with 6 SLM2048 (and 2024) switches we purchased last year. At first they seemed to work fine, but now I'm rebooting them about once a week at minimum. The problem is that ports start going dead. An affected computer will sometimes still be able to ping other machines, but no other traffic is allowed through. Rebooting the computer, giving it a new IP, new cables, etc. doesn't work. Rebooting the switch usually works for about a week or so, then ports start going dead again and another reboot is needed.
