Table 41 describes the 3U, 15 (3.5-inch) DAE power supply/cooling module LEDs.
The power supply/cooling modules are located above and below the LCCs. The units
integrate independent power supply and 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 supply supports a fully configured DAE and shares
load currents with the other supply. The drives and LCCs have individual soft-start
switches that protect the disk drives and LCCs if they are installed while the disk
enclosure is powered up.
The enclosure cooling system includes two dual-blower modules.
