To power on or power off LN use the power switches described below:

(You might hear a siren go off for 10 sec. when you turn the power on.)

This additional information provided in email from Thomas 06-Feb-2018: to power LN off entirely, you need to turn off all six electronics cabinets (C-SX, D-DX, F-SX, F-DX, B-SX, B-DX). For this, please open the cabinet doors that face the visitor gallery and turn the red main switch of the X-XX-CAB-PS unit to the "off" position. Only exception: the B-DX cabinet has to be opened from the side opposite of the visitor gallery. Please turn the cabinets back on once you are done with your vibration measurements.
