Lightning Protection
Requirements
Many measures have been taken to protect 3000 DSL Family from lightning.
However, if the lightning intensity exceeds a certain range, damage to the router is
still possible. To better protect the router from lightning, the following should be
considered:
Ensure the PGND wire of the chassis is well grounded.
Ensure the ground point of the socket of AC power supply is well grounded.
To enhance the lightning protection capability of the power supply, a
lightning arrester could be installed at the input end of the power supply.
As for the signal line outdoors to which the interface modules of 3000 DSL
Family routers are connected, such as ISDN line, telephone line, T1 line, etc,
a special lightning arrester should be installed at the input end of the signal
line to enhance the lightning protection capability.
Table Mount
Requirements
There is spacing reserved at the air inlet and outlet in the router so as to
facilitate the radiation of the router cabinet.
The workbenches have good radiation systems.
The workbenches are firm enough to support the weight of the router and
other installation accessories.
The workbench are well grounded.
