In fault-tolerant mode the 8260 does not reserve any specific power supply in reserve; instead, the reserved power is reserved across all the installed power supplies as shown in Figure 49. This ensures that the failure of any one power supply has no impact on the operation of the hub and the installed modules.

Figure 49. Load Sharing Power Supplies

If a power supply should fail, the power mode will be changed to

non-fault-tolerant and the system will supply the reserved power to the installed modules, so that network operations can continue without interruption. Upon the recovery of the failed power supply (for example, by replacing the failed power supply when the 8260 is operating from the other installed power supplies) the 8260 power mode will be changed automatically back to the fault-tolerant mode.

You can set your hub to operate in fault-tolerant mode using the following DMM command:
