*Step 1:* Make sure the software DAQ/read-out processes are not running. In other words, this means that the platform power off procedure should ONLY be done AFTER the DAQ/computer room racks are powered down. Confirm from the On-call DAQ expert and the uB operator on shift that this is the case before proceeding.

32 2 Sowjanya Gollapinni
b. Switch off the function generator (Strobe pulser) using its front panel on/off button.
33 2 Sowjanya Gollapinni
c. Switch off the fan switch on the fan front panel; verify the fan is off.
34 2 Sowjanya Gollapinni
d. Switch off the middle (CB2), top (CB1), and bottom (CB3) circuit breakers. 
35 5 Sowjanya Gollapinni
e. Switch off Slow controls using front panel switch on the slow controls panel  (gently pull the Chassis on/off switch and press down). The +5V, +3.3V, and RPS Status LEDs should turn off.
36 5 Sowjanya Gollapinni

*4. PMT/TRIG Rack power off:*
40 5 Sowjanya Gollapinni
a. Switch off Wiener PS using the red toggle switch on the front panel (gently push down the toggle switch for 3 seconds until the display turns off).
41 2 Sowjanya Gollapinni
b. Switch off the NIM bin using its front panel switch.
42 2 Sowjanya Gollapinni
c. Check that the PMT HV (CB3) bottom circuit breaker is off. If not, stop and call a PMT HV expert. 
43 2 Sowjanya Gollapinni
d. Switch off the middle (CB2) circuit breaker; verify the fan is off.
44 2 Sowjanya Gollapinni
e. Switch off the CB1 circuit breaker; verify NetGear network switch inside rack is off.
45 5 Sowjanya Gollapinni

h2. DRIFT HV rack Power-Off/On procedure for Planned Power Outages:
52 6 Sowjanya Gollapinni
53 7 Sowjanya Gollapinni
*First confirm from the On-call Drift HV expert and uB operator on shift that the DRIFT HV is ramped down as per procedure and is at 0 V.
54 6 Sowjanya Gollapinni
Do not proceed without this confirmation.*
55 1 Sowjanya Gollapinni
56 7 Sowjanya Gollapinni
Step 1: After confirming the above, ensure that the Glassman is at 0 V by looking at the power supply front panel. If the power happens to be off, the voltage is 0. 
57 7 Sowjanya Gollapinni
(At this point, if a power outage occurs, it is ok from a HV health standpoint.  The remaining steps are additions for a more graceful shutdown of the entire HV rack.)
58 6 Sowjanya Gollapinni
59 7 Sowjanya Gollapinni
a. After confirming Step 1, turn off the Glassman by pushing the orange on/off button on the front of the supply.
60 7 Sowjanya Gollapinni
b. Turn off the slow controls box by gently pulling the on/off switch on the front left side of the box and pushing it down.
61 6 Sowjanya Gollapinni
RPS can be turned off from the back of unit in the rack.
