AC power supply/cooling module
shows an example of the 3U, 15 (2.5- or 3.5-inch) disk drive DAE AC power
supply/cooling module with a power in (recessed) connector (plug) and status LEDs.
Figure 67 Example of a 3U, 15 (2.5- or 3.5-inch) DAE AC power supply/cooling module power in
(recessed) connector (plug) and status LEDs
describes the 3U, 15 (2.5- or 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.
