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 covers LED indicator information for Series 3 devices. See this article for information about older devices. See this article for SIRIS 4 devices

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.

SIRIS 3 Business/Datto NAS

Front panel

  • The power indicator LED surrounds the square power button and glows blue when powered up. 
  • The drive activity LEDs glow blue during normal use. When the appliance accesses a disk, 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.

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

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)
  • general error indicator (This will illuminate for hardware or system log-related errors)
  • activity on LAN 1
  • activity on LAN 2 (if configured)

General error indicator

Some of the more common causes for the general error indicator to illuminate are: 

  • A power supply may not be seated properly.
  • A fan may be spinning but not have a proper connection.
  • A fan may no longer be spinning.
  • A device component could be overheating.
  • You could have a cable that is unplugged or misconnected.

If the general error indicator light is on and you are unable to determine the cause, contact Datto Technical Support.

Back panel

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