Chapter 2 Installing the Cisco MDS 9100 Series
Removing and Installing Components
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 Figure 2-22.
