5.4.4 Installing 8250 Module in a Hub Not Managed by DMM

When a new 8250 module is inserted in a hub which is not managed by DMM, the process of applying power to the newly installed module is the same as what was described above. However, since there is no DMM, the Controller module is unable to acquire the power requirements of the 8250 module and to update its power budget table. Therefore, installing 8250 modules will result in the Controller module having an inaccurate power budget table which will render the power management of the controller module ineffective. Therefore, you are strongly recommended to ensure that a DMM is installed in the 8260 hub before you attempt to install 8250 modules in the 8260.

The process of applying power to a newly installed 8250 module in an 8260 not managed by DMM is shown in Figure 54.

5.5 Controlling Power to the 8260 Modules

You can use the following DMM command to enable/disable power to selected slots in your 8260.

SET POWER SLOT {slot} MODE {enabledisable}

Note that this command is only applicable if an 8260 module is installed in the selected slot. This command does not have any effect on the availability of power to the 8250 modules installed in the selected slot.

Also, note that this command is issued against the slot; therefore, it is not stored in the NVRAM of the 8260 modules installed in that slot.

5.6Power Management Considerations

∙In case of a power failure, the controller might bring down 8260 modules or reset the hub depending on the available power budget and types of modules installed in the 8260.
