Safety Information 11Nortel WLAN — Location Engine 2340 InstallationAC power suppliesMains AC power disconnect: The AC power cord(s) is considered the mains disconnect for the WLE 2340 and must bereadily accessible when installed. If the individual server power cord(s) will not be readily accessible for disconnectionthen you are responsible for installing an AC power disconnect for the entire rack unit. This main disconnect must bereadily accessible, and it must be labeled as controlling power to the entire rack, not just to the WLE 2340.Grounding the rack installation: To avoid the potential for an electrical shock hazard, you must include a third wiresafety ground conductor with the rack installation. If the server power cord is plugged into an AC outlet that is part of therack, then you must provide proper grounding for the rack itself. If the server power cord is plugged into a wall ACoutlet, the safety ground conductor in the power cord provides proper grounding only for the server. You must provideadditional, 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 overcurrentprotection per cord feed. If the power system for the equipment rack is installed on a branch circuit with more than20 Amperes of protection, you must provide supplemental protection for the server. The overall current rating of aconfigured server is less than 6 amperes.• Rating: In the U.S. and Canada, cords must be UL (Underwriters Laboratories, Inc.) Listed/CSA (CanadianStandards Organization) Certified type SJT, 18-3 AWG (American Wire Gauge). Outside of the U.S. and Canada,cords must be flexible harmonized () or VDE (Verband Deutscher Electrotechniker, German Institute ofElectrical Engineers) certified cord with 3 x 0.75 mm conductors rated 250 VAC.• Connector, wall outlet end: Cords must be terminated in grounding-type male plug designed for use in your region.The connector must have certification marks showing certification by an agency acceptable in your region and forU.S. must be Listed and rated 125% of overall current rating of the server.• Connector, server end: The connectors that plug into the AC receptacle on the server must be an approved IEC(International Electrotechnical Commission) 320, sheet C13, type female connector.• Cord length and flexibility: Cords must be less than 4.5 meters (14.8 feet) long.Warning! Do not attempt to modify or use an AC power cordset that is notthe exact type required. You must use a power cordset that meets the followingcriteria:
