∙When the hub is in the fault-tolerant mode, the reserved power is reserved across all installed power supplies. It is not an individual power supply out of all installed power supplies.

∙Although a power class does not apply to the 8250 module, the controller will see the 8250 module having the highest power class, 10.

∙Due to a possible power overload situation in a hub that has both 8250 and 8260 modules, it is recommended to install all 8250 modules first and also make sure that the hub has enough power to accommodate the modules.

∙To operate the hub in fault-tolerant mode, you must install N power supplies if N-1 can carry the load for the currently installed modules.

∙Without DMM in the 8260 hub, the power budget must be calculated manually when you add 8250 module(s) to the hub.

5.7Power Management Scenarios

Following are three power testing scenarios which were used to simulate a situation where a power failure occurs. We had three installed power supplies in the hub used for testing these scenarios.

∙A Power-Supply Failure - Scenario 1

In this scenario, the hub was operating in fault-tolerant mode. In order to simulate a power failure, we turned off one of the power supplies. We then received a message informing us that the system environment had changed and the power supply status had changed to faulty.

∙Show Hub

The show hub command was used to view the hub environment status and information on power supplies, temperature, and fans. Notice that the 3rd power supply is faulty. In addition, we could see one power supply LED on the active controller module flashing which meant that the corresponding power supply was faulty.
