dEntityExtEnvAirFlowStatus
Module: DLINKSW-ENTITY-EXT-MIB
OID (symbolic): DLINKSW-ENTITY-EXT-MIB::dEntityExtEnvAirFlowStatus
OID (numeric): 1.3.6.1.4.1.171.26.5.1.1.4.1.2
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: This object indicates the status of the air flow.
The fans' air flow direction must match the system's air flow direction to form an integrated air flow.
For example: In DXS-3600, the normal fans' air flow direction must match the power fan's air flow direction. The power fan blow the cold air from outside to inside, all the normal fans must blow the hot air from inside to outside. Or the power fan blow the hot air from inside to outside, all the normal fans must blow the cold air from outside to inside.
If one or more fans' air flow direction does not match the system's air flow direction, it will form an abnormal air flow. Then this log message will be triggered.
ok(1) : A recover event indicates the air flow back to normal.
abnormal(2): An alarm event indicates the air flow detects abnormal.
What is dEntityExtEnvAirFlowStatus?
Reports whether this unit's fans are blowing air in the same direction as the rest of the chassis: ok(1) means all fans' airflow direction matches the system's overall airflow (e.g. all blowing cold air in the same relative direction as the power supply's fan), while abnormal(2) means one or more fans are blowing the wrong way, which breaks the chassis's integrated cooling path and triggers an alarm.
