+The stick stays in a perpetual "TX Fault" state since the same SFP pin is used for both serial and TX Fault signaling, if that causes you issues (normally it shouldn't) you can issue the commands below to disable it. Note that it will disable both the TX Fault signal and Serial on the stick after boot.

+| Value (for `sgmii_mode` and `link_status`) | Speed                              |

+| 5                                          | 2.5 Gbps / HSGMII with auto-neg on |
+
+To change the default lan mode value you can use `fw_setenv sgmii_mode`. The firmware already has the value 5 by default and it is generally not necessary to change it.

+# EEPROM (I2C slave simulated EEPROM)
 The FS GPON-ONU-34-20BI does not have a physical EEPROM, the Falcon SOC emulates an EEPROM by exposing it on the I2C interface as required by the SFF-8472 specification.
 
 On the I2C interface there will be two memories of 256 bytes each at the addresses `1010000X (A0h)` and `1010001X (A2h)`, however in reality the memory available from the emulated EEPROM will be 640 bytes each but only the first 256 bytes will be exposed in the I2C interface.

 The Huawei MA5671A does not have a physical EEPROM, the Falcon SOC emulates an EEPROM by exposing it on the I2C interface as required by the SFF-8472 specification.
 
 On the I2C interface there will be two memories of 256 bytes each at the addresses `1010000X (A0h)` and `1010001X (A2h)`, however in reality the memory available from the emulated EEPROM will be 640 bytes each but only the first 256 bytes will be exposed in the I2C interface.

-
-```sh
-# scp rootfs.bin root@192.168.1.10:/tmp/

-
-## Backup of all partition
-
-Make a backup of all partitions, an easy way is:
-- On the stick run:
-```shell
-cat /proc/mtd
-```
-- For each mtdX run, on computer shell:
-```shell
-nc -l -p 1234 > mtdX.bin
-```
-And in the lantiq shell:
-```shell
-cat /dev/mtdX | nc 192.168.1.11 1234

-## Flashing a new rootfs via serial
-
-{% include alert.html content="Use this procedure only if you are unable to do the procedure from SSH" alert="Warning" icon="svg-warning" color="red" %}
-
-1. Connecting the molex-serial adapter and the serial to the computer as indicated in [Root Procedure](/ont-huawei-ma5671a-web-root)
-2. Open Tera Term (or any other programme capable of connecting to the serial terminal)
-3. Connect the SFP stick to the SFP molex, from the terminal you will have 5 seconds to lock the bootloader by doing a simple CTRL+C. Now upload the firmware image of the new rootfs partition to the stick with the command
-```
-FALCON => loady 0x80800000
-```
-At this point it will appear:
-
-{% include image.html file="ma5671a-root-13.jpg" alt="shell requiring `mtd2` upload" caption="shell requiring `mtd2` upload" %}
-
-{:style="counter-reset:none"}
-1. From the teratem menu do `FILE` → `TRANSFER` → `YMODEM` → `SEND` → `[mtd2.bin]`.
-It will start uploading the file at a speed of about 3-4 KBps. Now you will have to wait more than half an hour for the upload to complete.
-
-1. Once finished, the image loaded on the stick must also be saved to the corresponding system partition (the first of the 2) with the commands
-```
-FALCON => setenv committed_image 0
-FALCON => setenv image0_is_valid 1
-FALCON => saveenv
-FALCON => sf probe 0 && sf erase C0000 740000 && sf write 80800000 C0000 740000 && reset

+# EEPROM (I2C slave simulated EEPROM)
 The Zyxel PMG3000-D20B does not have a physical EEPROM, the Falcon SOC emulates an EEPROM by exposing it on the I2C interface as required by the SFF-8472 specification.
 
 On the I2C interface there will be two memories of 256 bytes each at the addresses `1010000X (A0h)` and `1010001X (A2h)`.
