AEM power
The AEM has an NT7D54AA (for AC power) or NT7D54AB (for DC
power) module power distribution unit (MPDU) on the left side (as you face
the AEM). The top circuit breaker in the MPDU controls power to the left-
side Application Module (closest to the MPDU). The bottom breaker
controls power to the Application Module on the right side of the AEM.
Figure 13 illustrates an AEM viewed from the front.
Note: Only the NT7D54AB (DC power) AEM is available in Europe.
