Also consider any additional interface equipment you need, such as transceivers, hubs, switches, modems,
Channel Service Units (CSU), or Data Service Units (DSU).
Before you install the router, have all the additional external equipment and cables on hand. For information
about ordering, contact a Cisco customer service representative.
The extent of your network and the distances between the network interface connections depend, in part, on
the following factors:
• Signal type
• Signal speed
• Transmission medium
The distance and rate limits referenced in the following sections are the IEEE-recommended maximum speeds
and distances for signaling purposes. Use this information as a guideline when planning your network
connections prior to installing the router.
If wires exceed the recommended distances, or if wires pass between buildings, give special consideration to
the effect of a lightning strike in your vicinity. The electromagnetic pulse 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.
Tools and Equipment
You need the following tools and equipment to install and upgrade the device and its components:
• ESD-preventive cord and wrist strap
• Antistatic mat or antistatic foam
• Number 1 and Number 2 Phillips-head screwdrivers
• #12-24 pan-head screws to secure the device to the equipment rack
• Cables for connecting to network ports (based on the configuration)
• Ethernet hub, switch, or PC with a network interface card for connecting to the Ethernet ports
• Console terminal that is configured for 115200 baud, 8 data bits, no parity, no flow control, and 2 stop
bits
• Console cable for connecting to the console port
• Ratcheting torque screwdriver with a Phillips head that exerts up to 30-pound force per square inch
(0.02-kilograms force per square millimeter (kgf/mm2)) of pressure
• Crimping tool as specified by the ground lug manufacturer
• Wire-stripping tools for stripping both 6 and 14-AWG wires
• Tape measure and level
• Ratcheting torque screwdriver with a Phillips head that exerts up to 15 inch-pounds (1.69 newton meters)
of torque for attaching the ground wire to the device
