Power supply and cooling module functions and features

The power supply and cooling modules are located to the left and right of the LCCs. The units integrate independent power supply and two dual-blower cooling assemblies into a single module.

Each power supply is an auto-ranging, power-factor-corrected, multi-output, offline converter with its own line cord. Each power supply supports a fully configured SAS expansion enclosure and shares load currents with the other supply. The drives and LCCs have individual soft-start switches that protect the drives and LCCs when they are installed while the SAS expansion enclosure is powered on. The enclosure cooling system includes two dual-blower modules.

Power supply and cooling module connectors and LEDs
