Chapter 5. 8260 Intelligent Power Management Subsystem

The 8260 provides extensive power management functions that allow you to take advantage of the modular load-sharing power supply system available on the 8260.

This chapter provides detailed information about the power management subsystem of the 8260.

5.1 Intelligent Power Management Subsystem

The 8260 comes standard with one load-sharing power supply but it allows you to have up to a maximum of four power supplies installed in a single 8260.

Each power supply is hot swappable and is accessible from the front panel of the 8260 hub as shown in Figure 42 on page 74.

The power consumed by the Controller, media and management modules currently installed in the 8260 is evenly distributed over all the installed power supplies. With the 8260 intelligent power management function, which is available thru the Distributed Management Module and the Controller module, you can perform the following functions:

∙

∙

∙

Assign power class (priority) to each 8260 module.

Display the power class assigned to each installed module.

Power up and power down individual slots housing 8260 modules using DMM commands.

∙

∙

∙

∙

Display the number and status of power supplies installed in the 8260.

Display the available power budget in your 8260.

Operate the 8260 in fault-tolerant or non-fault-tolerant mode.

Display the operational mode (fault-tolerant or non-fault-tolerant) of your 8260.

∙Automatically power-down the lower class (priority) 8260 modules if the failure of one or more power supply results in the power requirement of the currently installed modules to exceed the power capacity of the currently operational power supplies.

∙Ensure that the newly installed 8260 modules will be powered up only if there is enough available power in the 8260 to operate them.

The following sections are intended to provide detailed information about the various aspects of the intelligent power management in the 8260.
