Required equipment
This section describes the equipment that is required to update the BIOS version on an SN-L-Series firewall (SN-L-Series-2200 and SN-L-Series-3200).
-
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.
