my next problem is how can i use a cat5 cable reload routeros to my router boards. most of my boards have problems with the pci slots and power and i want to fix them all
Can you connecto to boards?
You can unplug poe from adapter to reboot.
You can make some cell phone device attached to power switch, that goes to routerboard, and when you call to that cell phone power switch resets routerbaord. We had this device for old trendnet 210 
.
i can connect to board but cant see wireless cards
some of the boards i can connect to board but cant use the ether port to access the boards
the rest can not even complete the boot process. what happens is they dont even beep .
