LED Status and Power

Status LED behavior

The status LED below the protective casing indicates the status of Rugged RAID Pro.

LED	State
On	The device is ready.
Blinking	The device is being accessed.
Fast blinking	A drive is not ready or has failed.
Off	Device inactive because it’s turned off or in power-saving mode.

Contact LaCie technical support if:

The status LED remains off while the device is connected to a power supply and to your computer. Confirm that Rugged RAID Pro is not in power-saving mode before contacting LaCie technical support.
The status LED continues to blink rapidly. One or both of your hard drives may have failed. Do not swap one or both hard drives onsite or in the field. Doing so will void Rugged RAID Pro’s warranty.

Power LED behavior

Rugged RAID Pro is designed to operate using power from the connection to your computer. If the connection isn’t delivering enough power for Rugged RAID Pro to operate, the power LED below the protective casing blinks.

If the power LED light is blinking, connect the power cable to Rugged RAID Pro and then connect the power supply to a live power outlet.

Power-saving mode

Your Rugged RAID Pro can conserve energy by entering power-saving mode. Managed by your computer, power-saving mode can extend the life of the hard drives by sparing them from working during extended periods of inactivity.

Operating system

You can initiate power-saving mode on your computer by performing one of the following:

Placing the host computer in sleep mode.
Mac OS—Go to System Preferences > Energy Saver to enable sleep mode for hard drives.
Windows—Go to Control Panel > Hardware > Power Options > Choose a power plan > Change advanced power settings. Click on Hard disk and Turn off the hard disk after. Choose the time to spin down USB hard drives.

To exit power-saving mode, review the table below:

Entering power-saving mode	Exiting power-saving mode
The host computer placed the product into power-saving mode due to inactivity.	Access the Rugged RAID Pro’s volume on the host computer. For example, copy files to its volume.
The computer is in sleep mode.	Wake up the computer.

Note on ejecting the volume and power-saving mode—Rugged RAID Pro enters power-saving mode when its volumes are ejected and the device remains connected to the computer. To access Rugged RAID Pro’s volumes, unplug the interface cable from the computer and reconnect it.
