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

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
