Safety Recommendations • Do not wear loose clothing that could get caught in the chassis. Fasten your tie or scarf and roll up your sleeves. Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals. (To see translated versions of this warning, refer to the appendix “Translated Safety Warnings.”)

Safety Recommendations • Never assume that power is disconnected from a circuit. Always check. • Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, and missing safety grounds. • If an electrical accident occurs, proceed as follows: — Use caution; do not become a victim yourself. — Turn off power to the system. — If possible, send another person to get medical aid. Otherwise, assess the victim’s condition and then call for help. — Determ

General Site Requirements Preventing Electrostatic Discharge Damage Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It occurs when electronic printed circuit cards are improperly handled and can result in complete or intermittent failures. Always follow ESD prevention procedures when removing and replacing cards. Ensure that the router chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, ensuring that it makes good skin contac

General Site Requirements Site Configuration Precautions The following precautions will help you plan an acceptable operating environment for your router and will help you avoid environmentally caused equipment failures: • Remember that electrical equipment generates heat. Ambient air temperature might not be adequate to cool equipment to acceptable operating temperatures without adequate circulation. Ensure that the room in which your system operates has adequate circulation. • Never place chass

General Site Requirements Equipment Racks The following tips will help you plan an acceptable equipment rack configuration: • Enclosed racks must have adequate ventilation. Ensure that the rack is not overly congested because each unit generates heat. An enclosed rack should have louvered sides and a fan to provide cooling air. • When mounting a chassis in an open rack, ensure that the rack frame does not block the intake or the exhaust ports. If the chassis is installed on slides, check the posi

Site Log Site Log The Site Log provides a historical record of all actions relevant to the router. Keep it in an accessible place near the chassis where anyone who performs tasks has access to it. Use the Installation Checklist to verify steps in the installation and maintenance of your router. Site Log entries might include the following: • Installation progress—Make a copy of the Installation Checklist and insert it into the Site Log. Make entries as each procedure is completed. • Upgrades and

Inspecting the System In addition, you might need the following additional external equipment: • Data service unit (DSU) to connect each serial port to an external network. • To connect a serial port to a T1 network, you need a T1 channel service unit/data service unit (CSU/DSU) that converts the High-Level Data Link Control (HDLC) synchronous serial data stream into a T1 data stream with the correct framing and ones density. (Some telephone systems require a minimum number of one bit per time u
