The power supply is hot-swapable. It has a built-in thumbscrew for ease of installation
and removal.
Each power supply includes a fan to provide cooling to the power supply. The 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.
In the 4U DAE, the power supplies provide four independent power zones. Each of the
hot-swappable power supplies has the capability to deliver 1300 W at 12 V in its
load-sharing highly-available configuration. Control and status are implemented
2
throughout the I C interface.
