What are power supply alarms on S series switches

For S series switches (except the S1700), run the display alarm command to display the power supply alarm.
For S series modular switches, run the display alarm all command to check whether there are any power supply alarms. The common power supply alarms are as follows:
- If the alarm information contains "Power is invalid for not support", an incompatible power module is installed in the device.
- If PWR_LACK and SWITCH_STAT sensor alarms are generated on the same power module, the power module is installed but is not connected to any power cable or the power switch is not turned on.
- If only the PWR_FAULT alarm is generated, the power module may experience a fan failure, output overvoltage, external short circuit, output failure, or input failure.
For S series fixed switches (except the S1700), run the display trapbuffer command to check whether there are any power supply alarms. The common power supply alarms are as follows:
- SRM_1. hwEntityInvalid 67966 //The power supply is not powered on or the electrical label is not loaded.
SRM/1/POWERFAULT: OID [oid] Power is abnormal.( EntityPhysicalIndex=[INTEGER], BaseTrapSeverity=[INTEGER], BaseTrapProbableCause=[INTEGER], BaseTrapEventType=[INTEGER], EntPhysicalContainedIn=[INTEGER], EntPhysicalName=[OCTET], RelativeResource="[OCTET]", ReasonDescription="[OCTET]")
- ENTITYTRAP_1. hwPowerInvalid //The power module does not work properly.
Entitytrap/1/POWERINVALID(t):OID [oid] Power supply is unavailable for some reason.(Index=[INTEGER], EntityPhysicalIndex=[INTEGER], PhysicalName=\"[OCTET]\", EntityTrapFaultID=[INTEGER])�?For details about how to troubleshoot power supply failures, see " Troubleshooting - Preliminary" in the product documentation. The following uses the S9300 and Sx7 series fixed switches (except the S1700) as an example.
