BTI7814 AC PEM
The BTI7814 chassis can be powered by four fan-cooled 2900W (53.5V) AC Rectifier
Modules (BT8A78ACM1). The four rectifier modules and the housing are included when
you order the chassis with the AC option (BT8A78CH14-KIT2-AC, BT8A78CH14-KIT3-AC).
It is recommended that you install your chassis with all four rectifiers.
NOTE:
The BTI7814 chassis can also be powered by an external rectifier. For
information on the external, standalone, Power-One
rectifier, see
"AC Rectifier" on page
