Table 1: Blade Server LEDs
DescriptionColorLED
Power off.OffPower
Main power state. Power is supplied to all server
components and the server is operating normally.
Green
Standby power state. Power is supplied only to the service
processor of the server so that the server can still be
managed.
The front-panel power button is disabled by
default. It can be re-enabled through Cisco UCS
Manager. After it's enabled, if you press and
release the front-panel power button, the server
performs an orderly shutdown of the 12 V main
power and goes to standby power state. You
cannot shut down standby power from the
front-panel power button. See the Cisco UCS
Manager Configuration Guides for information
about completely powering off the server from
the software interface.
