A major upgrade of the Sloan Digital Sky Survey (SDSS) fiber-fed spectrographs was completed in August, 2009. The upgraded spectrographs have 50% more fibers, extended wavelength coverage and much improved throughput. Large format VPH gratings and thick, fully-depleted CCDs are special features of the upgrade, which will enable the Baryon Oscillation Spectroscopic Survey (BOSS) project to obtain spectra of 1.4M galaxies and 160,000 quasars in five years of dark time observations. We report on the details of the upgrade, including the fiber system, optics, cameras and electronics.
