IN OK power LED:
Each hot-swap dc power supply has an IN OK power LED and an OUT OK
power LED. When the IN OK power LED is lit, it indicates that sufficient power is coming into the
power supply through the power cord. During typical operation, both the IN OK and OUT OK power
LEDs are lit.
•
DC power LED:
Each hot-swap power supply has a dc power LED and an ac power LED. When
the dc power LED is lit, it indicates that the power supply is supplying adequate dc power to the
system. During typical operation, both the ac and dc power LEDs are lit.
•
OUT OK power LED:
Each hot-swap dc power supply has an IN OK power LED and an OUT OK
power LED. When the OUT OK power LED is lit, it indicates that the power supply is supplying
adequate dc power to the system. During typical operation, both the IN OK and OUT OK power
LEDs are lit.
•
10 G link status LEDs:
These LEDs individually indicate the transmit and receive activity of each
10 Gb SFP+ transceiver.
•
System-error LED:
When this LED is lit, it indicates that a system error has occurred. An LED on
the light path diagnostics panel is also lit to help isolate the error.
•
Power-on LED:
When this LED is lit and not flashing, it indicates that the controller is turned on.
The states of the power-on LED are as follows:
–
Off:
Power is not present, or the power supply or the LED itself has failed.
–
Flashing rapidly (4 times per second):
The controller is turned off and is not ready to be
turned on. The power-control button is disabled. This will last approximately 20 to 40 seconds.
–
Flashing slowly (once per second):
The controller is turned off and is ready to be turned on.
You can press the power-control button to turn on the controller.
–
Lit:
The controller is turned on.
–
Fading on and off:
The controller is in a reduced-power state. To wake the controller, press the
power-control button or use the IMM Web interface. See the
Integrated Management Module
User’s Guide
for information on logging on to the IMM Web interface.
•
System-locator LED:
Use this LED to visually locate the controller among other servers. You can
use the
Integrated Management Module User’s Guide
to light this LED remotely.
