Off means the circuit is damaged.

line and null line are reversely connected), and you need to check the
power supply line.

It is used to connect to the power supply in the equipment room through a
power cord.

Installing a lightning protector for a network port
IMPORTANT:
Read the instructions for the lightning protector carefully before you install it.
If part of the network cable of a 10/100/1000 Mbps RJ-45 copper Ethernet port must be routed
outdoors, connect a lightning protector to the cable before you plug the cable into the port.
H3C recommends that you install a lightning protector for 10/100/1000 Mbps RJ-45 copper Ethernet
ports.
The switch does not come with any lightning protector.
