This read-write AlarmSeverity attribute lets an administrator override the default severity level assigned to the trap identified by the paired hcxAlmSevTrapId, with defaults documented per trap description. It allows a NOC to tune which conditions get escalated as critical versus which are treated as informational, matching local operational priorities. For example, an operator could raise the severity of a disk-fault trap to critical if PCMCIA disk failures have proven to cause frequent outages on their system.
