8265 Module Power Up Strategy
This section describes:
Ÿ Default 8265 Module Power Up Strategy
Ÿ
How to Specify 8265 Module Power Up Order.
Default Power Up Strategy
The controller module determines how much power an 8265 module requires before it permits the module
to power up.
The controller module employs the following powerup strategy:
Ÿ Current unallocated power budget must be sufficient to power up this module.
Ÿ
Media modules power up, in order, from slot 1 to slot 17.
Ÿ Media modules that have the highest power class setting power up first.
Ÿ Media modules continue to power up based on power class settings (from highest to lowest). This
process continues until the limit of the power budget is reached.
Ÿ If two or more media modules have the same power class setting, they power up, in order, from slot 1
to slot 17.
Note: Power-on occurs in this manner only if the installed do not configure from saved power
management configuration data stored in their NVRAM. For more details, refer to Chapter 4 the
section titled Saved Power Management Configurations.
Specifying Power Up Order
To specify the order in which 8265 modules power up, you change their power class settings.
To change the power class setting for a module:
1. Enter the SET POWER SLOT {slot} CLASS command, giving the new class value.
2. Press Enter.
For further information, see the 8265 Command Reference Guide.
