Operation Manual

Chapter 10 Using LOMlite 63
Once a fan has been reported to have failed, any subsequent recovery and repeated
failure will not be reported; that is, only one event is generated for the failure of each
fan. This is to prevent the event log being rapidly filled should the fan speed fall
very close to the failure threshold.
Once the fault has been corrected, you can clear the event log using the Solaris
lomctl clearevents command. This will automatically extinguish the Fault LED
if it is lit and re-enable checking of all fans. To re-enable checking of all fans and
extinguish the Fault LED without clearing the event log, use the LOMlite console
check command or Solaris utility lomctl check.
To display the current status of the fans, use the LOMlite console environment
command or the Solaris utility lominfo fan. These display both the current fan
speeds, expressed as a percentage of expected maximum, and the state OK or FAULT.
Note that reported speeds slightly in excess of 100% should not be considered to be
a problem.

The LOMlite device is powered by auxiliary power. It functions even when the rest
of the system is powered down.

Connector: LOM
