Tile modules power cycles in 2017

The purpose of this twiki is to keep track of the modules which have been power cycled during data taking (starting from April 24th, 2017), the reason and the actions required to fix the problem (if fixed). This would allow to identify problematic modules for further investigation.

The Tile Run Coordinator is responsible to keep this list up-to-date.

KNOWN PROBLEMATIC MODULES for which power cycle has been disabled: none
