1 # rail
5 A voltage rail that is enabled or monitored by a power sequencer device.
8 specify how to obtain the pgood status of the rail. You can specify more than
14 the rail with the pgood fault. However, all the related rails will likely appear
17 The "compare_voltage_to_limit" method is helpful when a rail fails to power on
22 rail. It is also helpful when a rail fails to power on during the power on
29 | name | yes | string | Unique name for the rail. Can only contain letters (A-Z, a-z), numbers (0-9), period (.), and underscore (\_). |
30 | presence | no | string | D-Bus inventory path of a system component which must be present in order for the rail to be present. If this property is not specified, the rail is assumed to always be present. |
31 | page | see [notes](#notes) | number | PMBus PAGE number of the rail. |
32 | is_power_supply_rail | no | boolean (true or false) | If true, this rail is produced by a power supply. Power supply rails require special error handling. If an error is detected in a power supply device, and the pgood status is false for a power supply rail, the power supply error is logged as the cause of the pgood failure. The default value of this property is false. |
33 | check_status_vout | no | boolean (true or false) | If true, determine the pgood status of the rail by checking the value of the PMBus STATUS_VOUT command. If one of the error bits is set, the rail pgood will be considered false. The default value of this property is false. |
34 | compare_voltage_to_limit | no | boolean (true or false) | If true, determine the pgood status of the rail by comparing the output voltage (READ_VOUT) to the undervoltage fault limit (VOUT_UV_FAULT_LIMIT). If the output voltage is below this limit, the rail pgood will be considered false. The default value of this property is false. |
35 | gpio | no | [gpio](gpio.md) | Determine the pgood status of the rail by reading a GPIO. |
