V2.03.74r Jun 2026

Improved support for double VLAN and default VLAN settings.

This build modifies peripheral clock distribution trees to strike a balance between processing capability and power utilization. By scaling down inactive physical communication buses (such as SPI, I2C, or UART lines) during idle loops, devices experience reduced thermal dissipation and lesser current draw.

Backup your running system configurations directly to an off-site server using an administrative command:

Added CLI controls to hide or show "admin_control" in the web interface. Bug Fixes:

This version number, , specifically refers to a 2021 firmware update for V1600D Series EPON OLT broadband equipment. v2.03.74r

: If this version number refers to a software update, v2.03.74r could represent a specific update to an existing application, possibly enhancing security, adding features, or fixing known bugs.

Fixes issues where DHCP relay packets were not properly processed. 3. Management and Diagnostics

One notable discovery from community analysis: in v2.03.74r , a developer left an Easter egg in the form of an unused UART debug menu accessible by grounding pin 7 of the main ASIC during boot. This menu reveals internal temperature sensors and flash wear level counts—features never mentioned in any official datasheet.

The DHCP relay, responsible for passing DHCP messages between ONUs (Optical Network Units) and the DHCP server, now correctly processes response packets, preventing IP address assignment failures.

If you encounter issues during the update process, such as a "Device Not Recognised" error, try using a different USB-C data cable or resetting the device to factory defaults before re-attempting the installation.
