outlet LED is still Off, restart the ePDU and then reconnect the device to
the ePDU.

For Managed (MA), Switched (SW), and (optionally)
Metered Input (MI) ePDUs, the LED normally flashes
RED when a CB is tripped. If the LED is alternately
flashing green and red, the outlet is On, but there is a
breaker overload.

alarm is present. Check the outlet settings, measurements, and
electrical conditions. The alarm does not clear until the outlet condition
is back to normal (cannot manually suppress the alarm).
