Power Supply Settings

Power Supply Settings

• Use the no power-supply global configuration command (the default) when installing one

power-supply module. The switch does not send an alarm when the second power-supply module is

missing.

• Use the power-supply dual global configuration command when installing two power-supply

modules. When both are operating properly, all applicable LEDs are green, and the switch does not

send an alarm. If a power-supply module is missing, the switch sends an alarm. An error message

appears and the appropriate power-supply LED turns red.

• Use the power-supply dual dc-feed global configuration command when two DC-input feeds are

connected to the DC-power source. When both are operating properly, all the applicable LEDs are

green and the switch does not send an alarm. If only one DC-input feed is connected, and there is at

least one DC-power-supply module installed, the switch sends an alarm. An error message appears

and the DC-power-supply LED for the missing DC-input feed turns amber. The LED for the

connected DC-input feed turns green.

• Use the no power-supply dual dc-feed global configuration command when only one DC-input

feed is connected. The switch does not send an alarm when the second DC-input feed is not

connected.

See the switch software configuration guide and switch command reference for more details on these

settings.
