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,
PEM A3 and PEM B3 work in 1+1 backup mode, PEM A4 and PEM B4 work in 1+1 backup mode.
