Hardware Description
Figure 3-10 Architecture of the NE40E-X8 AC power supply system
AC1
Installing the AC power module in the same cabinet as the chassis is recommended. If the AC power
module cannot be installed in the same cabinet as the chassis, it should be placed near the cabinet and
careful attention needs to be paid to the cabling. Two AC power modules work in 1+1 backup mode.
Each power module provides four circuit breakers and eight AC power inputs. Each circuit breaker is 20
A.
PEM A1 and PEM B1 work in 1+1 backup mode, PEM A2 and PEM B2 work in 1+1 backup mode.
