Controller Tray and Drive Expansion Tray Power- Fan Assembly

The power-fan assembly for the Sun StorageTek 2540 Array, the Sun StorageTek 2530 Array, and the Sun StorageTek 2501 Array is identical and interchangeable.

Note – A minimum of two disk drives must be operating in a controller tray or a drive expansion tray to avoid generating a power-fan assembly error.

The power-fan assembly contains an integrated cooling fan. The power supply provides power to the internal components by converting incoming AC voltage to DC voltage. The fan circulates air inside of the tray by pulling air in through the vents on the front of the assembly and pushing the air out of the vents on the back of each fan.

Each tray contains two power-fan assemblies. If one power supply is turned off or malfunctions, the other power supply maintains electrical power to the tray. Likewise, the fans provide redundant cooling. If one of the fans in either fan housing fails, the remaining fan continues to provide sufficient cooling to operate the tray. The remaining fan runs at a higher speed until the failed fan is replaced. Replace the failed fan as soon as possible.
