2.4.4 4GE-BYPASS WSIC Card
This card provides two electrical bypass links, but does not support hot swap. When the USG
is powered off or faulty, the traffic bypasses the USG for a direction connection between the
upstream and downstream devices of the USG, ensuring service continuity.
The 4GE-BYPASS card provides four GE RJ45 ports that form two bypass port pairs. Each
bypass port pair forms an electrical link bypass while both the member ports work at Layer 2.
The Layer-2 electrical link bypass works in either of the following states:
l
Working state
The USG runs properly. The data flows along Layer-2 links enter the USG for security
service processing.
l
Protection state
When the USG is powered off or becomes faulty, the data on Layer-2 links bypasses the
USG and is transmitted between the upstream and downstream devices, ensuring
availability. After the USG recovers, the Layer-2 electrical link bypass works in the
working state.
The four GE RJ45 ports on this card can be used as Layer-3 ports.

Name
Description
Ports 0 and 1 (RJ45)
Two 10/100/1000M autosensing Ethernet electrical ports
numbered 0 and 1. The two ports form a bypass port pair.
When working as the upstream and downstream ports on the
same Layer-2 link, the two ports form a bypass link. When
working at Layer-3, the two ports are both standard RJ45 ports.
Ports 2 and 3 (RJ45)
Two 10/100/1000M autosensing Ethernet electrical ports
numbered 2 and 3. The two ports form a bypass port pair.
When working as the upstream and downstream ports on the
same Layer-2 link, the two ports form a bypass link. When
working at Layer-3, the two ports are both standard RJ45 ports.
