Setting Power Class Manually
To set the power class for a module in a specified slot:
1. Enter the SET POWER SLOT {slot} CLASS command, giving the new class value.
2. Press Enter.
Note: Even though it has a power class setting, a controller module cannot be power managed. A
controller module always draws power when inserted in the switch, and cannot be powered down
using a terminal command.
Set Power Slot {slot} Class:
Use the SET POWER SLOT {slot} CLASS command to determine the order in which modules power down
if there is inadequate power to run the system. Modules with the lowest priority power down first.
The active controller module uses media module power class settings to decide:
Which modules should be powered down following a power supply failure.
Which modules should be powered down because of an overheat condition.
Power class settings range from 10 (highest) to 1 (lowest). The default power class setting for all media
modules is 3.
Notes:
1. Modules set to power class 10 do not power down automatically under any circumstances.
2. You cannot change the default power class setting for installed controller modules.
To set the power class for a media module, use the following command syntax:
SET POWER SLOT {slot} CLASS
In the following example, SET POWER SLOT CLASS is used to set the power class for a media module
installed in slot 1 to power class 7:
à
ð
8265ATM
>
set power slot 1 class
Enter class: 7
Slot ð1 power class is set to ð7.
8265ATM>

Power Class 10 Warnings:
A media module assigned a power class setting of 10 cannot be automatically powered down by installed
controller modules.
If a power supply failure causes a power deficit, a media module assigned a power class setting of 10
continues to run until you order it to shut down. Under some conditions (such as an extended
overheat condition), switch or module hardware damage may result.
To ensure that the controller module is able to automatically make all power management decisions
without waiting for user intervention, do not assign a power class setting of 10 to any media module
unless absolutely necessary.
