WARNING INFORMATION

	This section contains warning information for AC-powered systems.
	CAUTION: Use of controls or adjustments of performance or procedures other
	than those specified herein may result in hazardous radiation exposure.
	CAUTION: Danger of explosion if battery is incorrectly replaced. Replace the
	battery with only the same or equivalent type as that recommended by the
	manufacturer. Dispose of used batteries according to the manufacturer’s
	instructions.
Servicing	Service of this unit is to be performed by qualified service personnel only.
	Service of certain components and subassemblies in this equipment is
	accomplished by the replacement of Field Replaceable Units (FRUs). However,
	safety agency approval requires that the servicing of other subassemblies within
	this product be referred to 3Com’s service personnel.
	The trim enclosure and other mechanically secured plates serve as protection
	barriers from potential hazardous internal areas. No attempt should be made to
	troubleshoot internal components with these protective barriers removed
	without first disconnecting the equipment from main power.
Rack Mounting	This equipment is for use only in complete equipment where the acceptability of
	the combination is determined by the applicable safety agency in the country in
	which it is installed. This includes UL in the U.S.A., CSA in Canada, and TUV in
	Europe.
	CAUTION: Do not block the ventilation openings on the top and bottom of the
	unit during installation. A minimum of 1 rack unit (1.75”) space is required.
	Rack configurations with certain combinations of 3Com equipment installed in
	racks with a height greater than 50” (127 cm) may require a counter-balance
	weight, a stabilizer bar, or anti-tip legs to ensure rack stability in accordance
	with safety agency regulations.
	CAUTION: When attaching the rack-mount ears, you must use the
	factory-supplied screws. Using screws other than those supplied with the
	rack-mount ears voids your warranty and could damage the PCB.
