The labels in this figure correspond to the following LEDs.
 1 
1 Gb Ethernet port activity LED
  • Steady green indicates that the port is connected.
  • Flashing green indicates port activity.
 2 
1 Gb Ethernet port speed LED
  • Steady green indicates a 1 Gb Ethernet connection.
  • Steady amber indicates a 10 or 100 Mbps connection.
 3 
Fault LED
Steady amber when a critical hardware event is detected.
 4 
Locate LED
Steady blue when activated.
 5 
Power LED
Steady green indicates that power is connected and the appliance is turned on.
 6 
40 Gb Ethernet port activity LED
  • Steady green indicates that the port is connected.
  • Flashing green indicates that the transaction is ongoing.
 7 
10 Gb Ethernet port activity LED
  • Steady green indicates that the port is connected.
  • Flashing green indicates that the transaction is ongoing.
 8 
40 Gb Ethernet port activity LED
  • Steady green indicates that the port is connected.
  • Flashing green indicates that the transaction is ongoing.
 9 
Solid-state disk drive activity LED
  • Steady green indicates that the module is inserted fully.
  • Flashing green indicates the reading or writing of data on the disk.
 10

LEDs on the rear of the appliance.
The labels in this figure correspond to the following LEDs.
 1 
Fan LEDs.
  • Single flash when power is first applied.
  • Steady when the fan is operating at less than 1200 RPM or when there is a fault.
  • No illumination when operating normally or when no power is present.
 2 
Power module LEDs.
  • Steady green indicates that the module is connected to a power source.
  • Steady red indicates that the module is not functioning within design specifications.
  • Not illuminated indicates that there is no power to the module.
