SIRIS, ALTO and NAS: What Do the LED Indicators Mean on Series 3 Datto Devices?

Question

What do the LEDs convey on Series 3 Datto devices?

Environment

• Datto ALTO 3
• Datto SIRIS 3 Business/Datto NAS
• Datto SIRIS 3 Professional
• Datto SIRIS 3 Enterprise

Answer

This article explains the standard LED indicators on the front and rear panels of Datto devices. Your device may have a different form factor than those depicted, depending on its size and number of array drives.

ALTO 3

The Datto ALTO 3 uses two LED indicator lights on the front panel:

• The power indicator is green when the device is powered up and active, and red when the device is off. 
• The hard drive activity indicator flashes blue when the device accesses the HDD.

Front panel

• The power indicator LED surrounds the square power button and glows blue when powered on. 
• The drive activity LEDs glow blue during normal use. When a disk is accessed, the corresponding drive indicator will turn amber and blink rapidly. 
• The rectangular LED beneath the power button does not convey any information at this time.

Back panel

• Each Ethernet adapter, and the IPMI adapter, has a flashing green and amber LED indicating the link is active. The power indicator shows the device's power status.

SIRIS 3 Enterprise

Front panel

• Most of the LED indicators are located in a bank on the left side of the device's face, along with the power and reset buttons.
• Each drive bay has a multifunction LED that displays various color-coded messages. Refer to the table below for hard drive status indicator meanings:

The remaining status LEDs indicate, from top to bottom:

• hard drive activity (this will blink to indicate disk activity)
• generic device errors (This will illuminate for hardware or system log-related errors)
• activity on LAN 1
• activity on LAN 2 (if configured)

Back panel

• Each Ethernet adapter, and the IPMI adapter, has a flashing green and amber LED indicating the link is active. The power indicator shows the devices power status.
• The NIC activity LEDs will not illuminate if the device is not plugged into a gigabit connection.
