Runtime and Power off Bypass Settings
You can enable or disable the automatic activation of
hardware LAN Bypass function in the event of a power
failure. Hardware Bypass can automatically activate to
allow network traffic to continue.
The LAN bypass can be turned on or off in two system
states, i.e., power on and power off. The following are
the BIOS menu and illustration of the possibilities of LAN
bypass configuration in each state. Note that according to
the result from table 2, the ports are not bypassed in both
