If you need to use an EPON connection, you have two options:
su shell boardtype.sh -c epon # or set boardtype epon
Your computer's network adapter must be set manually to match the ONT's default subnet (e.g., IP: 192.168.100.10 , Subnet Mask: 255.255.255.0 , Gateway: 192.168.100.1 ).
The underlying chipset is the same for both GPON and EPON versions, but the optical module is different. In some cases, users report lower sensitivity or distance issues when running EPON on a GPON module, but for my setup (under 5km), it works perfectly.
While hardware replacement is an option, flashing a verified dual-mode or EPON-specific firmware is a highly cost-effective alternative. This guide outlines the technical requirements, the verification process, and step-by-step instructions to safely convert your Huawei HG8245H hardware. Understanding the Hardware Capability
Select the verified firmware file designed for GPON-to-EPON conversion. Click "Update" and touch the power cable or the Ethernet cord. The device will reboot several times. 4. Switching the Mode via Shell/CLI
Many HG8245H units are hardware-identical for GPON and EPON. You don't always need a firmware flash; you just need to adjust the software flag. This is the verified method to change the mode without reflashing the entire OS.
Through extensive community validation, two firmware versions have proven most stable for EPON conversions:
SU_WAP> set upport mode 2 (2 = EPON, 1 = GPON, 4 = dual-mode) SU_WAP> set optmode mode 197 SU_WAP> reboot
