Red power light of death on 3 of 4 Dlinks?

Hey guys,

Over the past few years we have acquired 4 different Dlink units, all of which have worked in the past. However, one by one, they have all stopped working.

We have powered them all the same way, with the 12v-5v converter specified by FIRST, directly from the 5v port of the PDB, from a 30 amp port on the PDB, and from a 12v wall wart adapter. So far, none of these methods have given us any trouble. They have all worked consistently.

It seems that after a while though, our Dlinks decide they don't want to run any more. We can still access the emergency flash page, and can attempt to update the firmware, but doing so has no affect. They flash blue lights at first, then sit with a red power light until we unplug them.

We have tried a 30/30/30 reset on all of them, and have tried to update the firmware with the emergency page.

Has anybody found a solution for this? I have seen old threads, but no solutions on them.

Thanks for the help,
Ozzy
