1. A frequency conversion system comprising:
a chassis with a plurality of slots, wherein each of the plurality of slots is configured to receive a frequency conversion unit, and wherein each frequency conversion unit is configured to convert a signal from a first frequency band to a second frequency band using at least one software-configurable local oscillator; and
a controller configured to
for each frequency conversion unit in the plurality of slots,
configure the first frequency band and the second frequency band of the frequency conversion unit,
switch the frequency conversion unit between an online mode and an offline mode, and
monitor the operation of the frequency conversion unit to detect a failure of the frequency conversion unit, and
when detecting the failure of a first frequency conversion unit in the online mode,
configure a second frequency conversion unit in the offline mode to match a configuration of the first frequency conversion unit, and
switch the second frequency conversion unit to the online mode, while switching the first frequency conversion unit to the offline mode.
