+
+### Normal procedure
+
+This ONT seems to be supporting a PLOAM password up to 288 bits in lenghth (36 ASCII characters, 72 Hex digits).
+
+The PLOAM password is stored into 32 bit chunks (4 ASCII characters / 8 Hex digits), each byte swapped.
+
+So, starting from the following PLOAM in ASCII format
+
+```
+A1B2C3D4E5
+```
+
+It gets translated into the following HEX value:
+
+```
+0x41314232433344344535
+```
+
+Which is then split into the following blocks (the last block gets padded with 0 to reach 8 digits)
+
+```
+BLOCK 0: 0x41314232
+BLOCK 1: 0x43334434
+BLOCK 2: 0x45350000
+```
+
+Each block is then byte swapped (i.e. read each sequence of two digits from right to left)
+
+```
+BLOCK 0: 0x32423141
+BLOCK 1: 0x34443343
+BLOCK 2: 0x00003545
+```
+
+And then you can finally persist it by changing the configuration file
+
+```sh
+# vi /config/scfg.txt
+```
+
+Append lines below to the file and save it to change the PLOAM password
+
+```
+INT CFG_ID_PON_REGISTRATION_ID0 = 0x32423141;
+INT CFG_ID_PON_REGISTRATION_ID1 = 0x34443343;
+INT CFG_ID_PON_REGISTRATION_ID2 = 0x00003545;
+```
+
+Reboot the ONT to apply the change.
