Chapter 2 Preparing for Installation

Unpacking and Repacking the Router

Distance Limitations

If wires exceed recommended distances, or if wires pass between buildings, give special consideration to the effect of a lightning strike in your vicinity. The electromagnetic pulse (EMP) caused by lightning or other high-energy phenomena can easily couple enough energy into unshielded conductors to destroy electronic devices. If you have had problems of this sort in the past, you may want to consult experts in electrical surge suppression and shielding.

Most data centers cannot resolve infrequent but potentially catastrophic problems without pulse meters and other special equipment. These problems can take time to identify and resolve, so take precautions by providing a properly grounded and shielded environment, with special attention to issues of electrical surge suppression.

Unpacking and Repacking the Router

The shipping package for Cisco XR 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 a location for installation.

Refer to the unpacking instructions (Cisco XR 12406 Router Unpacking and Repacking Instructions document) 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.

If you do not receive everything you ordered, contact a customer service representative for assistance. See the section titled “Obtaining Documentation, Obtaining Support, and Security Guidelines” section on page -xiv.
