[j-nsp] EX4200 generates power supply and fan alarms when environment is good

[Peter Tavenier]

Hi, 

On my EX4200 running version 12.3R1.7 is see the following alarms in the logging: 

Mar 21 08:46:46  <hostname> chassisd[1290]: %DAEMON-5-CHASSISD_SNMP_TRAP6: SNMP trap generated: Power Supply Removed (jnxContentsContainerIndex 2, jnxContentsL1Index 1, jnxContentsL2Index 3, jnxContentsL3Index 0, jnxContentsDescr Power Supply: Power Supply 2 @ 0/2/*, jnxOperatingState/Temp 1)
... 41 more times same type of alarms ...
Mar 21 08:46:46  <hostname> chassisd[1290]: %DAEMON-5-CHASSISD_SNMP_TRAP6: SNMP trap generated: Fan/Blower Removed (jnxContentsContainerIndex 4, jnxContentsL1Index 2, jnxContentsL2Index 1, jnxContentsL3Index 1, jnxContentsDescr FAN: Fan 1 @ 1/0/0, jnxOperatingState/Temp 1)
Mar 21 08:46:46  <hostname> chassisd[1290]: %DAEMON-5-CHASSISD_SNMP_TRAP6: SNMP trap generated: Power Supply Removed (jnxContentsContainerIndex 2, jnxContentsL1Index 8, jnxContentsL2Index 1, jnxContentsL3Index 0, jnxContentsDescr Power Supply: Power Supply 0 @ 7/0/*, jnxOperatingState/Temp 1)
Mar 21 08:46:46  <hostname> chassisd[1290]: %DAEMON-5-CHASSISD_SNMP_TRAP6: SNMP trap generated: Fan/Blower Removed (jnxContentsContainerIndex 4, jnxContentsL1Index 2, jnxContentsL2Index 1, jnxContentsL3Index 2, jnxContentsDescr FAN: Fan 2 @ 1/0/1, jnxOperatingState/Temp 1)
Mar 21 08:46:46  <hostname> chassisd[1290]: %DAEMON-5-CHASSISD_SNMP_TRAP6: SNMP trap generated: Power Supply Removed (jnxContentsContainerIndex 2, jnxContentsL1Index 8, jnxContentsL2Index 3, jnxContentsL3Index 0, jnxContentsDescr Power Supply: Power Supply 2 @ 7/2/*, jnxOperatingState/Temp 1)
... 32 more times same type of alarms ...

The environment is OK and also no alarms are active.

Is this a bug of did I configure something incorrect? 

With kind regards,
