Table 3-3 Fault Conditions Indicated By Blink Patterns; Table 3-4 Cellular Signal Strength Indicator - Lantronix PREMIERWAVE XC HSPA+ User Manual

Note: The fault LED blink patterns in this table are listed in order of priority.
Fault Conditions
No Ethernet link when eth0 (Ethernet Network) is
enabled.
No IP obtained from Ethernet network when eth0
interface is enabled.
No link (no SIM detected)
No cellular link when wwan0 (Cellular Network) is
enabled
No IP obtained from cellular networkwhen wwan0
(Cellular Network) is enabled and bridge mode is
disabled
When the internal device temperature is above
operating limit.
When the internal device temperature is below
operating limit.
Primary power source (barrel connector) is under-
volt (below 9 volts).
Secondary power source (terminal) is under-volt
(below 9 volts).
Signal Strength
Greater than or equal to -64 dBm
Greater than or equal to -85 dBm and less than -64 dBm
Greater than or equal to -75 dBm and less than -85 dBm
Greater than or equal to -86 dBm and less than -75 dBm

light. A "short" blink is a light that is on for only 0.2 seconds and followed by 0.2 seconds of
no light.
The diagnostic blink patterns reflect the highest priority fault condition. Also, the

Diagnostic LED will give an initial, identifying blink pattern to indicate the type of diagnostic
information it will display. All power and other non-network related diagnostic patterns,
with the exception of Temperature events and No SIM Card events, begin with one long
blink. All wired LAN related diagnostics patterns begin with two long blinks. All cellular-
related diagnostics patterns begin with four long blinks.
