2.The 8250 module sends module type information to the Controller module. The Controller module has no information about how much power is consumed by the module at this stage.

3.The Controller module forwards the module type of the newly inserted 8250 module to DMM.

4.DMM has a table which specifies the amount of power required by each 8250 module. This table contains an entry for each module Type. DMM retrieves the power requirements of the newly installed module from this table.

5.DMM sends the modules power requirements to the Controller module.

6.Controller module updates its power budget table. At this stage you will be able to display the correct power budget available in the hub using DMM commands.

The process of applying power to a newly installed 8250 module in an 8260 managed hub via DMM is shown in Figure 53.

Figure 53. Installing 8250 Modules in an 8260 Managed by DMM

Note: If the power consumption of the newly installed 8250 module results in a power deficit (that is, the total power required by the currently installed modules exceeds the available power supply) the Controller module cannot prevent the power from being used by the newly installed module.

Therefore, if you do not check the available power budget in your hub before installing an 8250 module, you may have a situation where the total power consumed by the modules exceeds the available power budget. In this case, the hub may be reset. Following the reset, power will be applied to all the 8250 modules and all the 8260 modules in the order of their power class and slot position as described in 5.2, ªPower Classº on page 74. This may result in one or more existing 8260 modules with low power class being denied power after the hub is reset. Therefore, you are strongly advised to ensure that there is enough power available in your hub before you attempt to install a new 8250 module in the 8260. You may refer to the tables provided in Appendix A, ªPower Requirements for 8250/8260 Modulesº on page315 to determine the power requirements of the 8250 modules.
