Lightning and AC Power Fault Interference
If signal wires exceed the recommended cabling distances, or if signal wires pass between buildings, you
should consider the effect that a lightning strike in your vicinity might have on the router.
The Electromagnetic Pulse (EMP) generated by lightning or other high-energy phenomena can couple enough
energy into unshielded conductors to damage or destroy electronic equipment. If you have previously
experienced such problems, you should consult with RFI and EMI experts to ensure that you have adequate
electrical surge suppression and shielding of signal cables in your router operating environment.
Tools and Equipment
You need the following tools and equipment to install and upgrade the router 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 router to the equipment rack
• Cables for connecting to the network ports (depending on the configuration)
For more information about cable specifications, see the
Troubleshooting
section.
• Ethernet hub, switch, or PC with a network interface card for connecting to the Ethernet ports
• Console terminal (an ASCII terminal or a PC running terminal emulation software) that is configured
for 115200 baud, 8 data bits, no parity, no flow control, and 1stop bit
• 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 (in-lb)
or 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-AWG and 14-AWG wires
• Tape measure and level
Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement
