Activity LED (green)
Drive LEDs:
1
Activity LED (green): Green LEDs are on all hot swap drives. When this green LED is lit, it indicates that
there is activity on the associated hard disk drive or solid-state drive.
• 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) SSDs, this LED is on solid when the drive is powered but not active.
Note: The drive activity LED might be in a different location on the front of the drive, depending on the drive
type that is installed.
2
Status LED (yellow): The state of this yellow LED indicates an error condition or the RAID status of the
associated hard disk drive or solid-state drive:
• When the yellow LED is lit continuously, it indicates that an error has occurred with the associated drive.
The LED turns off only after the error is corrected. You can check event logs to determine the source of
the condition.
• When the yellow LED flashes slowly, it indicates that the associated drive is being rebuilt.
• When the yellow LED flashes rapidly, it indicates that the associated drive is being located.
Note: The hard disk drive status LED might be in a different location on the front of the hard disk drive,
depending on the drive type that is installed.
Enclosure
The following illustration shows the controls, LEDs, and connectors on the front of the enclosure.
Notes:
1. The illustrations in this document might differ slightly from your hardware.
2. For proper cooling, a node filler has to be installed into every empty node bay in every configuration.
The enclosure supports up to four compute nodes.
The following illustration shows the node bays in the enclosure.
