1 # Monitoring Chassis Power Good
5 The power sequencer device provides a chassis power good (pgood) signal. This
8 The `phosphor-power-sequencer` application periodically reads (polls) the
16 If the chassis pgood state is false when it should be true, a chassis power good
17 (pgood) fault has occurred. See [Power Good Faults](pgood_faults.md) for more
20 ## Unable to read chassis power good signal
22 `phosphor-power-sequencer` may become unable to read the chassis power good
29 ### During power on
31 If `phosphor-power-sequencer` is unable to read the chassis power good signal
32 during a power on attempt, the application will do the following:
35   - Log an error specifying the power on attempt failed due to an inability to
36     read the chassis power good status.
37   - `phosphor-chassis-state-manager` will [power off](powering_off.md) the
41     - Log an error specifying an input power problem.
43     - Log an error specifying the power on attempt failed due to an inability to
44       read the chassis power good status.
49   - `phosphor-chassis-state-manager` will power the system
54 ### After power on
56 If `phosphor-power-sequencer` is unable to read the chassis power good signal
60   - Log an error specifying an inability to read the chassis power good status.
61   - Do **not** power off the system.
66     - Log an error specifying an input power problem.
67     - Power the system off and then on again. If the chassis's `Available`
