Note:
■
The figure is to illustrate the application and principle. The power cord you get from
the package and the socket in your situation will comply with the regulation in your
country, so they may differ from the figure above.
■
If you intend to connect the device to the ground via the PE (Protecting Earth) cable
of AC power cord, please make sure the PE (Protecting Earth) cable in the electrical
outlet is well grounded in advance.
4.3 Equipotential Bonding
Equipotential Bonding is the practice of intentionally electrically connecting all earthed
systems to the same grounding grid or connecting the grounding grids of all the
earthed systems together through the ground or overground metal so as to create
an earthed equipotential zone. When lightning occurs, the high voltage produced by
lightning current in all systems will meanwhile exist in their ground cables, and thus
all ground cables have the same electrical potential and basically eliminate the electric
strikes between the systems.
The figure bellow illustrates how to practice equipotential bonding in a network.

When equipotential bonding, please note that the cable should be copper wrapped Kelly
with its area being 6mm

at least. The shorter cable the better, and use a grounding
bar to establish an equipotential bonding point.
Note: The
equipotential bonding cable
is not provided with our product. If needed,
please self purchase it.

- Port 1 24 designed to connect to the device with a bandwidth of 10mbps 100mbps or 1000mbps each has a corresponding link act led 8
- Port 21f 24f designed to install the sfp transceiver these four sfp transceiver slots are shared with the associated rj45 ports the associated two ports are referred as a combo port which means they cannot be used simultaneously otherwise only rj45 port works the sfp ports support 1000m sfp module connection only 8
- Port 25 26 designed to install the 10gbps sfp transceiver or sfp cables t3700g 28tq also provides an interface card slot on the rear panel to install the expansion card tx432 of tp link for example if tx432 is installed you get another two 10gbps sfp ports 8
