The LCD screen is backlit in blue when the system is operating normally. When the system needs
attention, the screen is backlit in amber. When the system is in standby mode, the LCD backlight
will switch off after 5 minutes of inactivity. It can be turned back on by pressing the Select button
on the LCD panel.
Drive Status Indicator LEDs
Each hard drive in the FS7500 Controller has two status indicator LEDs. One LED displays
whether the hard drive is active (powered on). The other LED displays the current operational state
of the drive.
