Rodrigo,

To add to the previous poster...

When the Unit identification button is on, the Unit Identification LEDs on the front and back panels flash blue. This enables you to go behind the unit and look at the flashing blue light on the back You can turn off the flashing LED on the back of the unit off by pressing the Unit Identification button on the back panel. To turn off the Unit Identification LED, when the LED is on, push the Unit Identification Button.

The Unit Identification LED has the following states:

Off = System power is off, the system ID button has not been pushed, and there is no fault assertion condition (the system cover is on the device and there is no fault condition).

Flashing Blue = When the system ID button is pushed, the Unit Identification LED flashes blue if the system is in either standby mode or system power is on.

Solid Blue = System power is on, the system cover is on the device, and there is no fault assertion condition. The system ID button has not been pushed.

Flashing Amber = The system is on standby power, there is a fault assertion condition (for example, the cover has been removed from the device), and the system ID button has not been pushed.

Regards,
