The readout board for the ALICE TOF detector named DRM2 is now in the production phase: 88 boards are being produced (72 are needed in the experiment). Since the board
will operate in a radiation environment (0.13 krad total dose expected in 10 years and a flux of 0.26 KHz/cm$^2$ of hadrons with energy above 20 MeV), a complete irradiation campaign at the component level was performed. In this paper the focus is on the irradiation tests on a Microsemi Igloo2 FPGA and two different types of Avago SFP optical transceivers using a 100 MeV proton beam, available at the facility operated by
INFN-TIFPA at the Centro di Protonterapia in Trento. This paper also focuses on the board production test strategy.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
