Bug 9300l with firmware 17.09.04a?

[Hadronx]

I have a stack of switches consisting of 4 x C9300L-48P-4X with firmware 17.09.04a.
Yesterday, one power supply went into a disabled state, but my monitoring server via SNMP didn't detect any anomaly. Indeed, when checking with snmpwalk, that power supply doesn't even appear in the list (switch 1 - power supply A:

I believe this is a bug. Has this happened to anyone else before?

pretty sure its not displayed as it got disabled, make sure that you got no physical power issue at the first switch

  - You are only listing coEnvMonDupplyStatusDescr  ; and not the OID querying the actual status , but I presume it would be absent in that list too ; therefore you should also be sending all snmp traps from the device to the monitoring server and that server should    be able to handle traps with relevant (alerting) messages (too).
