2U, 25-drive expansion enclosure power supply and cooling module
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 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 expansion enclosure is powered on. The enclosure
cooling system includes two dual-blower modules.
