NSQM1GT4PFC
The NSQM1GT4PFC interface module provides four 10/100/1000BASE-T Ethernet copper ports.
When the firewall is operating correctly, the four ports operate as common data ports.
When the firewall is powered off, the four ports are divided into two bypass port pairs with ports
0 and 1 in one pair and ports 2 and 3 in another pair. The two ports in a pair can act as the uplink
and downlink interfaces for a Layer 2 link and form a bypass link. This enables traffic to be
transmitted through the firewall even if the firewall is powered off and ensures service
continuity.
