For example, I will connect the ETP48100-B1 power supply to the Huawei MA5800.
The kit included a regular ethernet patch cord with a standard pinout. I connected one side to the ESC port on the Huawei MA5800, and the other to the COM_OUT port on the ETP48100-B1.
I ordered the ETP48100-B1 for 100A, with two R4850G units of 50A each, for redundancy, if one fails, the OLT will continue to work on the other. Since the OLT also has two power boards for redundancy, we will connect both of them to the ETP48100-B1, as written in the instructions – preferably blue in +, and black in -.
Let’s look at the current emu on the MA5800 (usually only the board with coolers is configured there):
display emu
Let’s see the current transmission speed from OLT to emu:
display emu baudrate
Since the block was not detected automatically, I changed the speed from 19200 to 9600:
emu baudrate 9600
After this, the OLT saw the power supply:
Autofind an EMU, FrameID: 0 EMUID: 1 Type:Pwr4830L
By default, DIP 1 and 2 are enabled on the power supply.
Let’s look at the information:
display emu 1
Let’s move on to this emu:
interface emu 1
Let’s look at the production date of the parts:
display power manufacture info
Let’s look at the current alarms (as we see, the door opening sensor is not connected, so the “alarm” indicator on the power supply also flashes red):

Let’s look at the system parameters (as we see, there are parameters for batteries, although this unit does not support them, and I don’t need them, since there is a UPS + generator with automatic switching in front of the power supply):
