First off, i hope you aren't really using a PoE 84i (i don't even know that that exists) and that you are actually using a PoE 48i. Regardless, a blinking led on the PoE generally means that the PoE has failed in some way, I would check the output voltage of the PoE before i hooked it to another board. Also, you should be able to get the board repaired under warranty if it was a defective board, or if the PoE is new and putting out bad power, you should be able to get a new PoE and the supplier of teh PoE should be paying for a new RB.
A final bit of advice, if you have the option of replacing / exchanging the rb600, try to get a 433AH - there are a million and a half problems with the rb600, and a 433ah is much more reliable and just as robust as the 600
Hi i have the rb600 and yesterday something happen. The power led of the POE blinking. When i opened the case of rb600 OMG!!! The place of power supply on the Board was black and burned.
