software is enabled, 0 - power management control by hardware. |

Note that for any setting of pm_mgmt_en attribute hardware will |
|
not allow to power on any new line card in case system power |

|
Description: This file allows to unlock ASIC after thermal shutdown event. |
|
When system thermal shutdown is enforced by ASIC, ASIC is |
|
getting locked and after system boot it will not be available. |
|
Software can decide to unlock it by setting this attribute to |
|
1 and then perform system power cycle by setting pwr_cycle |
|
attribute to 1 (power cycle of main power domain). |
|
Before setting shutdown_unlock to 1 it is recommended to |
|
validate that system reboot cause is reset_asic_thermal or |
|
reset_thermal_spc_or_pciesw. |
|
In case shutdown_unlock is not set 1, the only way to release |
|
ASIC from locking - is full system power cycle through the |
|
external power distribution unit. |
|
Default is 1. |
|

Description: These files show the line reset cause, as following: power |
|
auxiliary outage or power refresh, DC-to-DC power failure, FPGA reset |
|
failed, line card reset failed, power off from chassis. |
|
Value 1 in file means this is reset cause, 0 - otherwise. Only one of |
|
the above causes could be 1 at the same time, representing only last |
|
reset cause. |
|
|
|
The files are read only. |
