12 AS420 Reference Manual

The power bypass mode is done using 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 AS420’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 and the unit passes self test, the relays switch the network and

equipment connections back into the AS420’s internal circuitry.

The AS420 powers up and remains in the power bypass mode for two

minutes. This delay allows for any power glitches that may occur as power

resumes after an outage. This minimizes the unit switching from power

bypass to normal operation.
