3.
(Optional.) If the 4G signal is not strong at the device location, you can use an extension cable
for the antenna and place the 4G antenna in a location where the 4G signal is strong.
No extension cable is provided with the firewall. Purchase one as required. To avoid extension
cable incompatibility with the firewall, contact the H3C sales personnel or sales agents for
compatible extension cables.

Connecting Ethernet cables
The Ethernet copper ports on the firewall support auto-MDI/MDIX. You can use either
straight-through or cross-over network cables to connect the ports. For more information about
Ethernet twisted pair cables, see "Ethernet twisted pair cable."
To connect an Ethernet cable:
1.
Connect one end of the Ethernet cable to the copper Ethernet port of the firewall, and the other
end to the Ethernet port of the peer device.
2.
Examine whether the LEDs of the Ethernet port are normal. For more information about LEDs,
see "Appendix B LEDs."
After connecting the firewall to the network, you can use the
ping
or
tracert
command to
examine network connectivity. For more information, see the related command reference.
