Give special consideration to the effect of a lightning strike in your vicinity if
wires exceed recommended distances, or if wires pass between buildings. The
electromagnetic pulse (EMP) caused by lightning or other high-energy
phenomena can easily couple enough energy into unshielded conductors to
destroy electronic devices.
Provide a properly grounded and shielded environment, with special attention to
issues of electrical surge suppression, to avoid the time loss to identify and resolve
future surge and distance issues after your router is installed.
The Cisco 12404 Internet router grounding architecture conforms to the DC-I
(DC-isolated) method of grounding as described in Telcordia GR-1089-CORE. A
DC-I architecture means that there is no connection between the DC return
terminal and the frame ground. DC return and frame ground are isolated from one
another at the router.
The shipping package for Cisco 12000 series routers is engineered to reduce the
potential of product damage associated with routine material handling
experienced during shipment. To minimize potential damage to the product,
transport these products in their Cisco-specified packaging. Failure to do so may
result in damage to the router or degradation of its performance. Also, do not
remove the Internet router from its shipping container until you are ready to install
it. The router should always be transported or stored in an upright position. Keep
the router in the shipping container until you have determined where you will
install it.
Refer to the unpacking instructions (Cisco 12404 Internet Router Unpacking
Instructions document number 78-13618-xx) that came with the router to unpack
it from the shipping pallet and verify the contents. This document also includes
instructions to repack the router if you need to transport it.
