on the Router, making sure that:

Enough clearance has reserved around the Router for adequate dissipation and
the cabinet is stable enough.
■
The correct power supply is used.
■
The connection of the PGND wire of the Router is correct and secure.
■
The connections with other devices, such as the console terminal, are correct.
It is very important for you to check the router installation, as the secure
connection, well grounding, and use of the correct power supply are essential to
the normal operation of the Router.
