You can replace individual fans without powering down the system. To replace the main fan tray, you must take the system to Standby mode and remove power from the system.

  • Page 84: Main Fans

    If main system fans 0, 1, 2, 3, 4, 5, or 6 are running slow or have stopped, the system will report alarms but will continue to operate. Resolve these failures by hot-swapping the fan. There is no impact to system availability. Sun Fire V1280/Netra 1280 Systems Service Manual • December 2003...
