WARNING Grounding the rack installation: To avoid the potential for an electrical shock hazard, you must include a third wire safety ground conductor with the rack installation. If the server power cord is plugged into an AC outlet that is part of the rack, then you must provide proper grounding for the rack itself. If the server power cord is plugged into a wall AC outlet, the safety-grounding conductor in the power cord provides proper grounding only for the server. You must provide additional, proper grounding for the rack and other devices installed in it. Overcurrent protection: The server is designed for an AC line voltage source with up to 20 amperes of overcurrent protection. If the power system for the equipment rack is installed on a branch circuit with more than 20 amperes of protection, you must provide supplemental protection for the server. If more than one server is installed in the rack, the power source for each server must be from a separate branch circuit. The overall current rating of a server configured with two power supplies is less than 3 amperes. CAUTION Temperature: The operating temperature of the server, when installed in an equipment rack, must not go below 5 °C (41 °F) or rise above 40 °C (104 °F). Extreme fluctuations in temperature can cause a variety of problems in your server. Ventilation: The equipment rack must provide sufficient airflow to the front of the server to maintain proper cooling. The rack must also include ventilation sufficient to exhaust a maximum of 1023 BTU's per hour for the server. The rack selected and the ventilation provided must be suitable to the environment in which the server will be used. WARNING Do not attempt to modify or use an AC power cord that is not the exact type required. You must use a power cord that meets the following criteria: 1. Rating: For U.S./Canada cords must be UL Listed/CSA Certified type SJT, 18-3 AWG. For outside U.S./Canada cords must be flexible harmonized () or VDE certified cord with 3 x 0.75 mm conductors rated 250 VAC. 2. Connector, wall outlet end: Cords must be terminated in grounding-type male plug designed for use in your region. It must have certification marks showing certification by an agency acceptable in your region and for U.S. must be rated 125% of overall current rating of the server. 3. Connector, server end: The connector that plugs into the AC receptacle on the server must be an IEC 320, sheet C19, type female connector. 4. Cord length and flexibility: Cords must be less than 4.5 meters (14.76 feet) long. 62 cc2300 Carrier Grade Server Product Guide
