Hello friends,
I have this completely factory restored OLT, it has no configurations whatsoever.
VERSION : MA5800V100R017C00
PATCH : SPH205
PRODUCT : MA5800-X15
I have a remote PC configured with the IP address 10.x.x.5/24. The PC is directly connected through a network cable, no element in between, I am able to login via SSH.
The OLT is pingable from the PC side:

Figure 1: Ping OLT from PC
But when I try to do the same from the OLT side, it times out.
Command:
ping 10.x.x.5
PING 10.x.x.5: 56 data bytes, press CTRL_C to break
