Lightning protection
To protect the router from lightning better, do as follows:
• Make sure the grounding cable of the chassis is well grounded. For how to connect the grounding
cable, see "
Grounding the router ."
• Make sure the grounding terminal of the AC power receptacle is well grounded.
• Install a lightning arrester at the input end of the power supply to enhance the lightning protection
capability of the power supply.
• Install a special lightning arrester at the input end of outdoor signal lines (for example, E1 line) to
which interface modules of the router are connected to enhance the lightning protection capability.
For how to install lightning protectors and surge protector, see " Installing a lightning protector for a
network port ," " Connecting the AC power supply to a power strip with lightning protection ,"
and Installing a surge protector ."
Space
• Because the router is heavy, install the router to the rack with the rack shelf.
• For ease of installation and maintenance, reserve at least 1 m (3.28 ft) of clearance between the
rack and walls or other devices.
• For heat dissipation, make sure the headroom in the equipment room is no less than 3 m (9.84 ft),
and an appropriately sized air conditioner is provided.
Power supply
• Make sure the power supply system at the installation site is stable and meets the requirements of
the power modules, including the rated input voltage.
• Select power modules based on the power consumption of the cards and fan trays. For more
information about system power consumption and technical specifications of power modules, see
" Power consumption ," and " Power module ."
