Attention: Press this button only when the appliance is hung.
Pressing this button when the appliance is booting up or operating
may make the appliance non-operational or corrupt the drives.
Operator Information panel
The LEDs on this panel give status information for your appliance.
See “Operator information panel”on page 5 for more information.
Hard Drive Status LED
Each of the hot-swap drives has a Hard Drive Status LED. When
this amber LED is on continuously, the drive has failed. When the
LED flashes slowly (one flash per second), the drive is being
rebuilt. When the LED flashes rapidly (three flashes per second),
the controller is identifying the drive.
Hard Drive Activity LED
Each of the hot-swap drives has a Hard Drive Activity LED. When
this green LED is flashing, the controller is accessing the drive.
