Managing Power Systems | 35 |
The EME cannot automatically power off a module that is assigned a power class setting of 10.
For example, if a power supply failure causes a power deficit (or if a chassis overheat condition develops), a module that is assigned a power class setting of 10 continues to run until you order it to power off. Under some conditions (such as an extended overheat condition), chassis or module hardware damage may result.
To ensure that the EME can make all power management decisions automatically, do not assign a power class setting of 10 to any switch fabric module or interface module unless it is absolutely necessary.
Power State
You can enable or disable power to any slot in your CoreBuilder 9000 chassis.The EME allocate power to a module in the disabled slot. All slots are enabled by default.
If there is:
■Sufficient power available to meet the requirements of the new module, the EME enables power to the specified slot and reduces the power budget by the amount of power that module consumes.
■Insufficient power to meet the requirements of the new module, the module remains in
A CoreBuilder 9000 module that was powered off due to a lack of sufficient available power is in power pending state. The module will be automatically powered on again by the EME when sufficient power becomes available.
