Dell Powerconnect 6224F requiring power cycle to reboot (or reload)

it does look like memory is low, or all used up,

says  messages dropped for lack of resources,

I wonder if I deleted backup image?

anything make sense here?

It just acts like you did not do it, but it steady ping toward it does not continue responding afterwards until a power cycle,

this is a brand new factory fresh unit, I cut out of box myself removing tape off power port,

I did upgrade firmware, first to 3.3.15.1 and now to 3.3.16.1,

I would gladly set to any version of firmware if it would work. I have to be able to restart remotely.

I have erased setup over and over to no avail, I removed the 10 gig back ports in case they were affecting it somehow.

I have a lot of these only one was having this issue and now this brand new one that I copied the configuration to. 

ping drops and never returns until power cycled, same if reboot from cli telnet,

it sits like this for a long, time, never had it come out of it without power cycle,

could I be being impatient? have left it for 5 or so minutes,

I have several used ones and a new one that all do the same thing.

Hello,

Are you by any chance stacking any of the ones you are seeing the problems with?  if so you might want to try reseating (or removing if possible) any installed expansion modules.  Also may want to try swapping out network cables (stacking in particular) to see if it makes a difference. 

Definitely sounds like a configuration issue at first, but have you definitely determined that?  May try to zero out the configuration and see if the problem persists.  If it does, then it's either a hardware, firmware, or metadata issue.  that would at least eliminate the configuration as the issue. Next you could delete any metadata by going back to factory defaults to see if that fixes it.  If still persists it is probably the firmware.  Make sure after you have run the firmware upgrade, that you also run the boot code update if required....should be in the release notes with the firmware download.  It should have instructions on how to do it and whether or not it is required, since not all releases require it.

Hope this helps.
