DOIAbstract
This paper presents the test strategy employed during the installation of the CARLOS end ladder boards developed for the Silicon Drift Detectors (SDD) of ALICE. Each CARLOS board compresses the data provided by the front-end electronics of one SDD and sends them via an optical link of 800 Mbit/s to the data concentrator card (CARLOSrx) located in the counting room. The paper describes the integration of the CARLOS boards in the final SDD system, including its cooling and mechanical support, the power supply distribution and the optical interconnections. The results of the tests performed after each step of the installation sequence are reported
