1.19.10 Fault Code
Description
Port# Fault#:
If there is a problem with a port, a fault code will be sent. Below is a
list of all possible codes along with a brief description.
Code#1 = MPS Absent (Maintaining Power Signature):
This fault code is sent when
there is a valid device connected to the port, but it is not drawing the minimum
current required to keep the port powered. This value is about 8mA.
Code#2 = Short:
This code is sent when the port senses a shorted connection and is
automatically powered down to prevent an unsafe situation.
Code#3 = Overload
: An “Overload” fault code is sent when the power used by a
connected device exceeds typical operation.
Code#4 = Power Denied
: The port did not power up due to power availability or
port priority.
Code#5 = Thermal Shutdown:
The port automatically shuts down to prevent
damage from excessive heat.
Code#6 = Startup Failure
: An error occurred in the startup procedure.
Code#7 = Classification Failure:
An error occurred in determining the classification.
