Figure 4-111 aci_switch Function Call
Allow the second AMU to be used without manual
intervention, if the first AMU-PS is down. An installed and
running Dual-AMU is necessary for this function. See
Table 4-50.
Only use the -f option if the -n option is no longer
functioning. There is a risk that anomalies may be caused in
the AMU database.
