The Cisco MDS 9216 power supplies can be configured to be redundant or combined. By default, they are configured as redundant, so that if one fails, the remaining power supply can still power the entire system. For information about how to configure the power supplies, refer to the Cisco MDS 9000 Family Configuration Guide.

The power supplies are illustrated in Figure 1-2.

Fan Module

The Cisco MDS 9216 Switch supports a hot-swappable fan module with four fans. The fan module provides 270 CFM (cubic feet per minute) of cooling, allowing 400 Watt of power dissipation per slot. Sensors on the supervisor module monitor the internal air temperature. If the air temperature exceeds a preset threshold, the environmental monitor displays warning messages.

If one or more fans within the fan module fail, the Fan Status LED turns red. Individual fans cannot be replaced, you must replace the entire fan module. The Cisco MDS 9216 Switch continues to run if the fan module is removed, as long as preset temperature thresholds have not been exceeded. This means you can swap out a fan module without having to bring the system down. To replace a fan module, see the “Removing and Installing the Fan Module” section on page 2-31.
