AC power supply/cooling module
shows an example of the 2U, 25 (2.5-inch) DAE AC power supply/cooling
module with a power in (recessed) connector (plug) and status LEDs.
Figure 59 Example of a 2U, 25 (2.5-inch) DAE AC power supply/cooling module power in (recessed)
connector (plug) and status LEDs
describes the 2U, 25 (2.5-inch) DAE power supply/cooling module LEDs.
The power supply/cooling modules are located to the left and right of 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.
