Using the CLI to Power Modules Up or Down

You can power down a properly working module from the command-line interface (CLI) by entering the
set module power down mod command. The module is marked as power-down in the show module
Status field. Enter the set module power up mod command to check if adequate power is available in
the system to turn the power on for a module that was previously powered down. If not enough power is
available, the module status changes from power-down to power-deny.

Effect
System log and syslog messages are generated.
•
The system disables the lower wattage power supply; the higher
•
wattage supply powers the system.
System log and syslog messages are generated.
•
System power is increased to the combined power capability of both
•
supplies.
The modules marked as power-deny in the show module Status field
•
are brought up if there is sufficient power.
System log and syslog messages are generated.
•
If the power supplies are of equal wattage, there is no change in the
•
module status because the power capability is unchanged.
If the power supplies are of unequal wattage and the lower wattage
supply is removed, there is no change in the module status.
If the power supplies are of unequal wattage and the higher wattage
supply is removed, and if there is not enough power for all previously
powered-up modules, some modules are powered down and marked
as power-deny in the show module Status field.
• System log and syslog messages are generated.
System power is decreased to the power capability of one supply.
•
If there is not enough power for all previously powered-up modules,
•
some modules are powered down and marked as power-deny in the
show module Status field.
• System log and syslog messages are generated.
The lower wattage supply is disabled.
•
System log and syslog messages are generated.
•
• System power equals the combined power capability of both
supplies.
The system powers up as many modules as the combined capacity
•
allows.
