11C Cabling Reasonably
In the ac tual network environment, you may need cable outdoors and indoors, and
the requirements for cabling outdoors and indoors are dif ferent. A reasonable cabling
system can decrease the damage of induced lightning to devices.
Note: It's not rec ommended 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 n etwork devices in different
■
floors.
Outdoor c ables sho uld be buried a nd paved to the indoor through ba sement. A
■
piece of steel wire should be paved underground alo ng the pipe an d connected to
the lightning protection terminal of the building for shielding. Before connecting the
cable to the device, install a signal lightning arrester on the correspo nding port.
When an aerial cable is set up, the cable should be thro ugh a metal pipe (15m long
■
at least1 bef ore coming into the buildi ng. The two ends of this metal pipe should
be grounded. Before conn ecting the cable to the device, install a signal lightnin g
arrester on the corresponding port.
It’s not necessary to pave STP cables through pipes. The s hielded layer of STP cable
■
should be well grounded. Before connecting the c able to the device, inst all a signal
lightning arrester on the corresponding port.
