About This Guide 48 VDC Power System Warning The customer 48 volt power system must provide reinforced insulation between the primary AC power and the 48 VDC output. Statement 128 Multiple Power Cord Warning This unit has more than one power cord. To reduce the risk of electric shock when servicing a unit, disconnect the power cord of the power strip that the unit is plugged into. Statement 137 Circuit Breaker (15A) Warning Warning This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. (240 VAC, 10A international) is used on the phase conductors (all current-carrying conductors). Statement 13 Grounded Equipment Warning Warning This equipment is intended to be grounded. Ensure that the host is connected to earth ground during normal use. Statement 39 Safety Cover Requirement Warning The safety cover is an integral part of the product. Do not operate the unit without the safety cover installed. Operating the unit without the cover in place will invalidate the safety approvals and pose a risk of fire and electrical hazards. Statement 117 Faceplates and Cover Panel Requirement Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place. Statement 142 Cisco ASA 5500-X Series Hardware Installation Guide x
