Cabling Reasonably

In the actual network environment, you may need cable outdoors and indoors, and
the requirements for cabling outdoors and indoors are different. A reasonable ca-
bling system can decrease the damage of induced lightning to devices.
Note: It 's not recommended using Ethernet cables outdoors. When cabling
outdoors, please use a signal lightning arrester.
Requirements for Cabling Outdoors
■
Aerial cabling without safeguard is not allowed.
■
It's not allowed cabling down the building to connect network devices in different
■
floors.
Outdoor cables should be buried and paved to the indoor through basement. A
■
piece of steel wire should be paved underground along the pipe and connected
to the lightning protection terminal of the building for shielding. Before connect-
ing the cable to the device, install a signal lightning arrester on the correspond-
ing port.
When an aerial cable is set up, the cable should be through a metal pipe (15m
■
long at least) before coming into the building. The two ends of this metal pipe
should be grounded. Before connecting the cable to the device, install a signal
lightning arrester on the corresponding port.
It's not necessary to pave STP cables through pipes. The shielded layer of STP
■
cable should be well grounded. Before connecting the cable to the device, install
a signal lightning arrester on the corresponding port.
