This port provides power to eBUS devices. If the power draw by the connected
devices reaches the maximum level allowed, the eBUS Limit LED lights. If the power
consumption exceeds the allowed threshold, the IPCP shuts off the eBUS port and
lights the eBUS Overload (Over) LED. If that occurs, you must resolve the hardware
cause of the power overload before the IPCP can successfully restore function to this
port. Once the power consumption of the port is reduced to below the maximum
overload condition threshold, the eBUS port automatically re-enables and resumes
function.
If additional power supplies are required for an eBUS system, consider the following:
Do not connect power from both the IPCP and the supplemental power supply to
•
any eBUS device.
Do not allow power from the supplemental power supply to flow to the IPCP.
•
See the following diagram as an example of a system where both an IPCP and a
supplemental power supply are included in the eBUS topology.
