During system operation, an event may repeatedly occur that the server internal fan
shows the failed state (log: "SYS_FAN at FT0/FMx has FAILED.") and then gets
back to normal (log: "SYS_FAN at FT0/FM1 is OK.") one second later.
Output example (Excerpt from the showlogs command result of ALOM):
JAN 26 15:36:25: 00040066: "SYS_FAN at FT0/FM1 has FAILED."
