• System rack kits are intended to be installed in a rack by trained service technicians. If you install the kit in any other rack, be sure that the rack meets the specifications of a computer manufacturer rack. CAUTION: Do not move racks by yourself. Due to the height and weight of the rack, a minimum of two people should accomplish this task. • Before working on the rack, make sure that the stabilizers are secured to the rack, extended to the floor, and that the full weight of the rack rests on the floor. Install front and side stabilizers on a single rack or front stabilizers for joined multiple racks before working on the rack. • Always load the rack from the bottom up, and load the heaviest item in the rack first. • Make sure that the rack is level and stable before extending a component from the rack. • Use caution when pressing the component rail release latches and sliding a component into or out of a rack; the slide rails can pinch your fingers. • After a component is inserted into the rack, carefully extend the rail into a locking position, and then slide the component into the rack. • Do not overload the AC supply branch circuit that provides power to the rack. The total rack load should not exceed 80 percent of the branch circuit rating. • Ensure that proper airflow is provided to components in the rack. • Do not step on or stand on any component when servicing other components in a rack. SAFETY: Systems Using -48-VDC Power Supplies • This product is intended for restricted access locations (dedicated equipment rooms, equipment closet, or the like) in accordance with Articles 110-5, 110-6, 110-11, 110-14, and 110-17 of the National Electrical Code, American National Standards Institute (ANSI)/National Fire Protection Association (NFPA) 70. • Connect the equipment to a 48-V direct current (DC) supply source that is electrically isolated from the AC source. The 48-VDC source is to be reliably connected to earth. Product Information Guide NOTE: While grounding techniques may vary, a positive connection to a safety (earth) ground is a requirement. • Wire the unit with copper wire only, and unless otherwise specified, use 14 American Wire Gauge (AWG) wire, and protect it with a 7.2-ampere (A) minimum to a 20-A maximum protective device or a 25-A maximum protective device when used with 90.C wire. CAUTION: A qualified electrician must perform all connections to DC power and to safety grounds. All electrical wiring must comply with applicable local or national codes and practices. CAUTION: Before connecting safety ground or power cables to the connector, ensure that the power is removed from the DC circuit. To ensure that the power is off, locate the circuit breaker on the DC source circuit (usually at the power distribution of the battery distribution fuse bay). Switch the circuit breaker to the off position and, if available, install an approved safety locking device on the circuit breaker or switch. CAUTION: When stranded wiring is requir...
