Power
Bypass
The S Lite can operate in a power bypass mode where the S Lite
passes the signal from the network to the equipment and vice
versa whether in a powered state or not.
The power bypass mode uses relays that switch the network and
equipment connections. When the unit is powered and stable, the
relays have the network and equipment connections switched into
the S Lite’s internal circuitry. When the unit loses power, the
relays switch the network connection to a direct connection path
to the equipment connection. When power is reestablished the
relays switch the network and equipment connections back into
the S Lite’s internal circuitry.
