OmniSwitch 6800-48 won't work (leds no light,fan works))

[STR]

Hello,

My omniswitch worked for me only for 3 month (now I don't have warranty :/ )

First days after breakdown, LED called "ok" light, and after some time (1-2 minutes) 0 goes to 1
Rest LED's not light, LED's on ports too. Thats all. Now "ok" LED not lighting (all leds not light) and led display 0.
I tried to communicate with omniswitch by console but my terminal not received any characters from switch

Is there any hope?

Regards,
STr
PS. I think that I buy old but proffesional switch all will be fine, but i was wrong. My colleague says "It's not cisco, I'm sorry. cisco works always" (he is cisco specialist, but I belive that the cisco is not eternal)
