environment power CLI command to determine if the
power supply is shut down. If the status is shutdown, then

shuts down the lower capacity power supply only if it detects
a mismatched pair of power supplies and the mode is
redundant or if there is a transition from combined to
redundant mode. If both power supplies are the same capacity
or the mode is combined, Cisco SAN-OS never shuts down a
power supply.
