+This SFP module is made by CIG, it also has a CIG MAC address, and is identical
+to the [FS XGS-ONU-25-20NI](ont-fs-XGS-ONU-25-20NI.html).
+See also its page for further information.

+
+
+## Login via Telnet
+
+The SFP module has a telnetd running on `192.168.100.1` port `23`.
+To connect to its IP a fibre cable has to be connected!
+
+| User                | Password (Enable Password)             |
+| ------------------- | -------------------------------------- |
+| SN (`ALLGNNNNNNNN`) | 8 digit HMAC-MD5 based on Uppercase SN |
+
+Use the following form to generate the password:
+
+{% include cig_password_xgspon.html password_len="8" %}
+
+
+After logging in via Telnet, you will first access the MiniShell with user
+privileges:
+```
+ONT>
+```
+
+To do anything at all, you have to enter the elevated shell, i.e. execute the
+`enable` command:
+```
+ONT> enable
+#ONT>
+```
+
+## Change the GPON serial number
+
+The default GPON serial number is `ALLGYYXNNNNN` and is equal to the serial
+number printed on the label of the SFP+ module.  
+(`ALLG` = vendor, `YY` = manufacturing year, `X` = manufacturing month maybe, `NNNNN` = sequential number)
+
+When connected via Telnet (and `enable`d) the GPON serial number can be read and
+changed using the `/system/misc/eqsn` command.
+A reboot is required for the changes to take effect.
+
+**ATTENTION:** changing the GPON serial number will also change the Telnet login
+username and password.
+
+e.g. to change the GPON serial number from `ALLG24NNNNNN` to `AAAANNNNNNNN`:
+```
+#ONT>/system/misc/eqsn get
+eqsn: ALLG24NNNNNN
+#ONT>/system/misc/eqsn set "AAAANNNNNNNN"
+---ATECMDRESULT--- OK
+#ONT>/system/shell/
+#ONT/system/shell>reboot
+
+```
+
+The GPON serial number currently in use can be seen with the
+`/traffic/pon/show onu` command:
+```
+#ONT>/traffic/pon/show onu
+

+Linux shell commands (including `sh`) can be executed from the `/system/shell` menu:
