IX15 LEDs

The IX15 LEDs are located on the top front panel. During bootup, the front-panel LEDs light up in sequence to indicate boot progress.

Power (PWR)

Off

No power.

Solid green

DC power is connected to the device.

Solid blue

Device is ON and connected to the internet.

Alternating green/blue

Device is ON and either Ethernet or Cellular networks are connecting.

SIM

Indicates that a SIM is in use:

Off

No SIM is present

Solid green

SIM1 is active.
Solid blue

SIM 2 is active
Solid red

SIM failure.

LTE

Indicates that the status of the cellular module and the ETH Ethernet port connection:

Solid yellow (or orange)

Initializing or starting up.
Flashing yellow (or orange)

In the process of connecting to the cellular network and to a device on its ETH port.

 Flashing white

ETH port connection established and in the process of connecting to the cellular network.
Flashing green

Connected to 2G or 3G1 and is in the process of connecting to any device on its ETH port, or nothing is connected to the port.

 Solid green

Connected to 2G or 3G and also has a device linked to its ETH port.
Flashing blue

Connected to 4G LTE and in the process of connecting to a device on its ETH port.

 Solid blue

Connected to the 4G LTE and also has a device link to its ETH port.

Alternating Red/yellow (or orange)

Upgrading firmware.

WARNING! DO NOT POWER OFF DURING FIRMWARE UPGRADE.

XBee

Indicates the XBee status:

Off

XBee interface is disabled.

Flashing green

Network discovery requested by customer.

Solid red

XBee interface is enabled but the XBee service is not running.

Alternating Red/yellow (or orange) Updating local XBee.

WARNING! DO NOT POWER OFF DURING UPDATE.
Solid green

XBee interface is enabled and XBee service is running.

Flashing yellow (or orange)

Updating a remote XBee.

Solid blue

XBee active discovery running.

Flashing red

Recovering local XBee.

Signal quality indicators

LEDs labeled 1 through 5 Indicate the cellular service quality level.

Signal bars Weighted dBm Signal strength % Quality
-113 to -99 0% to 23% Bad
-98 to -87 24% to 42%

Marginal
-86 to -76 43% to 61% OK
-75 to -64 62% to 80% Good
-63 to -51 81% to 100% Excellent

The weighted dBm measurements are negative numbers, meaning values closer to zero denote a larger number. For example, a -85 is a better signal than -90.

Note See Cellular signal quality explained for more information regarding how signal strength is calculated and subsequently displayed via the LED indicators.

Ethernet Link and Activity

The LEDs on the ETH port indicate that the Ethernet network interface is up and there is activity on the network interface.
