BTI7814 DC PEM
The BTI7814 chassis can be powered by up to four DC PEMs (BT8A78PEM3-DC). Two
DC PEMs are used to provide the A feeds, for a total of twelve channels on the chassis.
Each DC PEM powers six channels that feed various functions. A non-redundant
configuration requires two DC PEMs. A redundant configuration requires four DC PEMs.
It is recommended that you configure your chassis with four DC PEMs and connect each
PEM to its own (separate) power supply and return.
