5. After a brief period of time, cOS Core will be fully initialized and the E20 is ready for
configuration using a direct console connection or via the default management Ethernet
interface.

Important: Protecting Against Power Surges
It is recommended that the purchase and use of a separate surge protection unit from a
third party is considered for the power connection to the E20 hardware. This is to ensure
that the E20 is protected from damage by sudden external electrical power surges
through the power cable.
Surge protection is particularly important in locations where there is a heightened risk of
lightning strikes and/or power grid spikes.
Any surge protection unit should be installed exactly according to the manufacturer's
instructions since correct installation of such units is vital for them to be effective.
