Problem Resolution
Electrostatic Discharge can cause a BreadCrumb to
appear to power up (Status LED indicates power is
on with a white light, which can sometimes appear
pale blue or pale green), but fail to start-up.
Manually reboot the device by turning off or
disconnecting power to the device and turning
power back on.
For BreadCrumbs powered by PoE, in order to
avoid sparking and possible damage to the device,
be sure to connect the powered Ethernet cable to
the BreadCrumb before applying power to the
power supply.
Rapid power cycling can cause a BreadCrumb JR
to appear to power up (“PWR” LED is lit) but fail
to start-up.
Turn off power to the device, wait at least 10
seconds and turn power back on. The
BreadCrumb should start-up normally.
Connecting a cable assembly which has an active
power source (like a battery pack) to a
BreadCrumb JR can cause the power to fluctuate
at startup if it is connected with an unsteady hand.
This can cause the BreadCrumb to appear to power
up (“PWR” LED is lit), but fail to start-up.
● Disconnect the cable assembly, wait 10
seconds, and try to make the connection
again more smoothly.
● Try connecting the cable assembly to the
BreadCrumb before connecting or
applying power to the power supply.
