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.
