Note: If a power supply fails and there is still enough power in the hub to operate all the installed modules, the modules will continue their operation without any interruption.

You can configure your 8260 to operate in non-fault-tolerant mode using the following DMM command:

SET POWER MODE non_fault_tolerant

The current power mode setting for your 8260 can be displayed using the following DMM command:

SHOW POWER MODE

An example of the output for this command is shown in Figure 48.

Installing one power supply more than the required number of power supplies to power all the installed modules will allow you to set the power mode to

fault-tolerant. In the fault tolerant mode, one power supplys worth of power is kept in reserve. The reserved power is not available to any currently installed or yet-to-be installed modules. It will only be made available to be used by the modules if at least one power supply fails or until you switch the hub from the fault-tolerant mode to non-fault-tolerant mode. In other words, in the

fault-tolerant mode the power required by the current and yet-to-be installed modules cannot be greater than the number of installed power supplies minus one (N-1).

The amount of power available to the modules when the hub is operating in fault-tolerant mode is determined by the number of installed modules as shown in Table 14.
