BYPASS on Startup

Hi,
I have a NGAF 5100. I see when I plug in the AC cord the bypass led still on until whole system boots up.
What does it mean?
Can this create a storm broadcast if I aggregate the interface eth2 and eth3 ?

In particular I have to put two NGAF in HA mode. I want to be sure that there aren't issue if one firewall during the boot.
Thanks.

The bypass LED on your NGAF 5100 staying on until the whole system boots up is likely an indication that the device is going through a power-on self-test (POST) process. During this process, the device is checking all its components to make sure they are working correctly before fully booting up. Once the POST process is complete, the device will boot up and the bypass LED should turn off.

Regarding your question about aggregating the interface eth2 and eth3, it is unlikely that doing so would create a storm broadcast. Link aggregation, also known as NIC teaming, allows you to combine multiple network interfaces into a single logical interface. This can improve network performance and provide redundancy in case one interface fails. However, it is important to configure link aggregation properly to avoid network issues such as broadcast storms. If you are unsure about how to configure link aggregation on your  NGAF 5100, you should consult the device's documentation or seek the assistance of a qualified network administrator.

The bypass LED on your Sangfor NGAF 5100 indicates the status of the network interface card (NIC) bypass feature. When the bypass LED is on, it means that the NIC bypass feature is enabled, and network traffic can continue to flow even if the firewall is powered off or rebooting.

During the boot process, it's normal for the bypass LED to remain on until the firewall completes its initialization and begins processing network traffic. This should not cause any broadcast storms or other network issues, as long as the interfaces are properly configured and connected to your network.

Regarding your question about configuring two NGAF devices in HA mode, it's important to ensure that both devices are properly configured and synchronized before enabling HA mode. This includes configuring the network interfaces, setting up the synchronization interface, and verifying that the devices can communicate with each other.

During the boot process, one of the NGAF devices will become the active device, while the other remains in standby mode. If the active device experiences any issues during the boot process, the standby device will take over to ensure continuity of service. As long as both devices are properly configured and synchronized, the boot process should not cause any issues with the HA setup.

Every hardware on bootup does some checks which we called Power On Self Test and until all these checks are find OK the systems will not be started. So the LEDs in these cases just indicates the status, If there color are red or amber then the situation is alarming otherwise for green everything is fine.

startup deive take 2 minites to upload the OS. then screen will be normal if not then shutdont the NGAF and on after 5minutes

bypass LED staying on during boot on NGAF is normal. It shouldn't cause broadcast storms during aggregation, and in HA, traffic is switched to the second device when the first isn't functioning.

When we start the device it take two minutes to start up suting this time light will be yellow after two minutes if successfully boot light will be green other wise shutdown the device

It mean bypass mode is enabled

Go to logs, After startup, the ALARM indicator may flash, which means device is writing logs.

The NGAF 5100's bypass LED displays the state of the system's bypass feature.
