IBM 8260 manual Show Power Slot slotall, An example of the output for this command is shown in on

with slot 1 to 17. The Controller module will repeat this process for all other power classes in descending order of their priority until either all the modules are powered up or the available power supply is exhausted.

Note: You cannot assign a power class to the 8250 modules and they do not take part in the power management. This means that the Controller module cannot exert any control over the 8250 modules as far as the power management is concerned. Therefore, during a power failure, the 8250 modules cannot be powered down by the Controller module and during the hub power up, the 8250 modules will all be powered up regardless of the availability of the power. In this respect, the 8250 modules operate in a manner similar to the 8260 modules which are assigned power class 10.

If you try to assign a power class to an 8250 module, the command will be aborted. An example of this is shown in Figure 43.
