Media Attention Led

Hi,

After I had 3 CRC errror, my PV 122T died, it gave me error code: BF. I called Dell Tech and they sent me the new one. This morning I put one of the bad tapes, did long erase but the job never finish so I kill veritas services and after that I see the Media Attention Led is ON. I couldn't turn it off. Anybody knows how to turn off that led?

Thanks,
