5.4.2 Installing 8260 Module in an 8260 Not Managed by DMM
When a new 8260 module is inserted in the hub and there is no DMM installed in
the 8260, the process of powering up the module is identical to what was
described above. However, since there is no DMM, you will not be able to
display the current power budget despite the fact that the Controller module has
accurate information about the current power budget available in the hub.
The process of applying power to a newly installed 8260 module in an 8260 not
managed by DMM is shown in Figure 51.

5.4.3 Installing 8250 Module in a Hub Managed by DMM
When a new 8250 module is inserted in the hub and the hub is managed by a
DMM, the following process will take place:
1. Full power is applied to the module. This is because of the fact that the 8250
modules do not take part in the power management and as soon as they are
installed in the hub, they will draw the amount of power that is required for
their proper operation.
