For the Cisco MDS 9140 Switch and the Cisco MDS 9120 Switch, the fans should not be removed for
prolonged periods of time during operation. If one fan module fails, a single healthy fan module can
temporarily provide sufficient cooling to maintain switch operation under normal conditions, but the
failed fan module should be replaced as soon as possible. See
