Configuring the Power Supply Mode
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 modeUses 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 modeUses 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.
To configure the power supply mode, follow these steps:
- In the Fabric Manager Physical Attributes pane, expand Switches and then select Hardware. Click the Power Supplies tab.
- In Device Manager, click Physical > Power Supplies.
- Configure the power attributes for the power supply.
- Click Apply in Device Manager or click the Apply Changes icon in Fabric Manager.
