Relay contact:
The relay consists of the two middle contacts of the terminal block
on IES308-2F's top panel. The two terminal block connector are
used to detect both power faults and port faults. The two wires
attached to the Fault contacts form an open circuit when:
(1) IES308-2F have lost power from one of the DC power inputs,
One of the ports for which the corresponding Port alarm DIP Switch
is set to ON is not properly connected.
If neither of these two conditions occur , the alarm circuit will be
closed.
Power Input:
IES308-2F have redundant power input, provides one terminal
block (4 bits) for PWR1 and PWR2 input. The redundant power can
be used single and used two self-governed power to supply to the
system, PWR1 and PWR2 input at the same time, when neither of
these two power fails, the other power acts as a backup, and
automatically supplies power needs, ensure running Ethernet
