Updating the BIOS from a USB key

This section describes the procedure of updating BIOS on an SN-L-Series (SN-L-Series-2200 and SN-L-Series-3200) model firewall to version R1.05 from a USB key.

Required equipment

• A computer with a terminal emulator installed, e.g., Putty with a baud rate of 115200, and the PL23XX USB-to-Serial driver installed if the firewall is connected over a USB-C port,

• A blank USB flash drive formatted to FAT32,

• A USB-A to USB-C cable, or an RJ45 to DB9 serial cable (RS232),

• An SN-L-Series model firewall running in BIOS version R1.02.

NOTE
This operation can also be performed directly on a monitor, by using an HDMI/HDMI cable.
In this case, plug a USB keyboard into the SNS firewall as well.
