Obscured AGN have hard X-ray spectra and may be expected to have high FIR fluxes, due to dust re-emission of absorbed flux from soft X-rays to the NIR. At high redshifts (z > 1) this FIR dust emission will be redshifted into the submillimeter. We present submillimeter observations of 135 of the 370 X-ray sources in the 1 Ms Chandra Deep Field-North exposure. The error-weighted mean 850-micron flux of the sources is significant at 1.21 0.27 mJy. These X-ray sources contribute about 15% of the extragalactic background light at 850-micron. The submillimeter excess is found to be the strongest in the optically faint X-ray sources that have radio detections at 20cm, which is consistent with these sources being obscured AGN at high redshift.
