Media Drive Example
• The left Power/Activity LED (blue) is solid when a drive has power and flashes when the drive
is in use.
• The right Fault LED (red) is lit when an error is detected, or if the drive is rebuilding or
initializing. It flashes fast when it is initializing or rebuilding an array. It flashes slow when there
is a suspected problem with the drive.
