Configuring Power Supplies
Switches in the MDS 9000 Family have two redundant power supply slots. The power supplies can be
configured in either redundant or combined mode.
•
Redundant mode—Uses the capacity of one power supply only. This is the default mode. In case of
power supply failure, the entire switch has sufficient power available in the system.
• Combined mode—Uses the combined capacity of both power supplies. In case of power supply
failure, the entire switch can be shut down (depends on the power used) causing traffic disruption.
This mode is seldom used, except in cases where the switch has two low power supply capacities
but a higher power usage.
Note The chassis in the Cisco MDS 9000 Family uses 1200 Watts when powered at 110 volts, and 2500 Watts
when powered at 220 volts.
Guidelines for Power Supplies with Different Capacities
When power supplies with different capacities are installed in the switch, the total power available
differs based on the configured mode.
