power supply. All types of NSGs are intended to be installed in
restricted access locations.
Management Interfaces
Harmonic offers several methods for configuring NSG devices and
monitoring their status. All management interfaces listed below connect
to the NSG over LAN, via its ETH1 Ethernet port.
Caution: Harmonic strongly recommends using an Ethernet network
that is isolated from any other networks or subnets at your site for
management of the NSGs.It ensures adequate security, and prevents
possible disturbances to the normal operation of NSG devices due to
uncontrolled network activity.
