1.3.1.1 AC Power Supply/Cooling Module
Two Power Supply/Cooling modules (
) are supplied mounted in the rear of the enclosure
as part of the subsystem core product.
PSU voltage operating ranges are nominally 115V or 230V AC, selected automatically.
.
Four LEDs mounted on the front panel of the Power Supply/Cooling module (see
) indi-
cate the status of the PSU and the fans.
1.3.1.2 Multiple Power Supply/Cooling Modules
The Altos S205F / S200F Storage System must always be operated with two Power Supply/Cooling
modules fitted. The two Power Supply/Cooling modules operate together so that if one fails the
other maintains the power supply and cooling while you replace the faulty unit.
Module replacement should only take a few minutes to perform but must be completed within 10
minutes from removal of the failed module.
