Device status LEDs

Once power has been established, your device will initialize and attempt to connect to the network. Device initialization may take 30-60 seconds. By default your EX12 will attempt to use DHCP to establish an Internet connection either through its cellular modem or the ethernet port.

Cellular connectivity status is indicated by the color-coded LTE light.
Cellular signal strength is indicted by the signal strength indicator lights.
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.

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

Ethernet connections are confirmed via the light corresponding to the EX12 port number.
