Fan Failure

When two or more fans fail, a two-minute timer starts. After two minutes, the
switch is powered down and must be rebooted to restart it. This protects the
switch from possible overheating.
ProCurve recommends that you replace a failed fan tray assembly within one
minute of removing it.
