Power Supplies

The Cisco MDS 9200 Series supports dual hot-swappable 845-W AC power supplies, each of which can
supply sufficient power to the entire chassis should one power supply fail. The power supplies monitor
their output voltage and provide status to the supervisor module. To prevent the unexpected shutdown of
an optional module, power management software only allows a module to power up if adequate power
is available.
The Cisco MDS 9200 Series 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 on how to configure the power supplies, see the Cisco MDS 9000 Family
NX-OS Fundamentals Configuration Guide.
The power supplies, which are accessed from the rear of the chassis, are illustrated in
