• Drive status LEDs: These LEDs are on SAS or SATA hard disk drives and solid state drives. When one of
these LEDs is lit, it indicates that the drive has failed. When this LED is flashing slowly (one flash per
second), it indicates that the drive is being rebuilt. When the LED is flashing rapidly (three flashes per
second), it indicates that the controller is identifying the drive.
• Drive activity LEDs: These green LEDs are on all hot swap drives.
– When this LED is flashing, it indicates that the drive is actively reading or writing data.
– For SAS and SATA drives, this LED is off when the drive is powered but not active.
– For NVMe (PCIe SSD) solid state drives, this LED is on solid when the drive is powered but not active.
