An AC power chassis is 2 U high. Install the AC power chassis in the same cabinet as the
device. If they cannot be installed in the same cabinet, install them in as close proximity as
possible. The two AC power chassis work in 1+1 backup mode. Each AC power chassis has
four circuit breakers and eight AC power inputs. The current of each air circuit breaker is 20
A.
