Power Cycling and Resets in Phoebus

This page will explain how to use Phoebus to power cycle and reset different detector components.

Before power cycling anything: before power cycling anything, let the Run Coordinator know what you're planning on doing!!!

What do I need to do for what particular component?

The table below should help you decide what action you need to take based on the problematic component.

Problem Component	Subsystem	Fix
pmt01, pmt02, pmt03, pmt04, pmt05, pmt06, pmt07, pmt08	PDS	Reset the PDS readout crate Power cycle the offending PDS readout crate
NTB	TPC	Power cycle crate 01 to fix the NTB

Controlling the PDS readout crates

Once you've done that, you should see a screen like this:

To power cycle the crates, you need to hit the switches, as highlighted in red below:
