Abstract
The high flux of charged particles interacting with the CMS Forward Hadron Calorimeter PMT windows introduced a significant background for the trigger and offline data analysis. During Long Shutdown 1, all of the original PMTs were replaced with multi-anode, thin window photomultiplier tubes. At the same time, the back-end electronic readout system was upgraded to {\mu}TCA readout. The experience with commissioning and calibration of the Forward Hadron Calorimeter is described as well as the {\mu}TCA system. The upgrade was successful and provided quality data for Run 2 data-analysis at 13 TeV.
