In this article I will show how I connected the ETP48100-B1 power supply to Huawei MA5608T.
Huawei ETP48100-B1 is very powerful and heavier than similar models, it is 48V 50A, but from the minuses – batteries cannot be connected to it, that is, it does not have a UPS function.
Once I upgraded Zabbix to version 6.4 and noticed that the “Template ICMP Ping” template stopped working on new devices, it continued to work on old ones, but if you add a new device, a warning was displayed:

Before updating, first of all, open the menu “Report” – “System Information” and make sure that the keys are not used, this will be indicated by the entry – “Database history tables use primary key – No”, if the keys are used, then this entry simply will not be.

I will use ONT from different manufacturers, EPON board H803EPFD for 16 ports.
I will give an example of setting up an ACL to restrict access to Telnet, SSH, SNMP on Huawei S2300 series switches.

Let’s say a Huawei ETP4830 power supply unit (UPS) or a similar model is connected to the Huawei OLT MA5600 series, now I will show several SNMP OIDs with which I took data on voltage and battery charge:
