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: This file allow to overwrite line card VPD hardware write
|
|
protection mode. When attribute is set 1 - write protection is
|
|
disabled, when 0 - enabled.
|
|
Default is 0.
|
|
If the system is in locked-down mode writing this file will not
|
|
be allowed.
|
|
The purpose if this file is to allow line card VPD burning
|
|
during production flow.
|
|
|
|
The file is read/write.

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.
|
|
|
