Technical Specifications

Specifications	Criteria
Power	Two versions of the HotWire 8600 DSLAM chassis
	are available: an ac power version and a dc power
	version.
	The ac version can be connected to a dc source to
	provide power redundancy. With the dc version,
	two separate dc sources may be employed to
	provide power redundancy.
	The ac version accepts ac power (100 ± 250V,
	50 ± 60 Hz) and converts it to dc power. The
	maximum current draw is less than 1.75 amps, or
	75 watts @ 110 Vac. At maximum configuration
	with 3 DSL cards, the system will not exceed
	85 watts of power dissipation.
	The HotWire 8600 DSLAM chassis dc version
	operates from a standard ±48 Vdc power supply
	(±40.0 to ± 60.0 Vdc). The maximum current draw
	is 2 amps. At maximum configuration with 3 DSL
	cards, the system will not exceed 75 watts of
	power dissipation.
	Each power version distributes ±48 Vdc power
	from the power source to individual cards via the
	backplane.
Grounding	A ground lug is located at the rear of the HotWire
	8600 DSLAM at the center. It accepts 14 AWG
	wire.
	A non-insulated banana jack is located at the left
	front of the 8600 DSLAM providing a ground for
	the ESD wrist strap plug.
Cooling and Air Handling	The internal fan module is installed in the chassis
	to provide cooling.
	A built-in feature shuts off power to the circuit
	cards if a chassis overheats because of fan failure.
	If the temperature in the chassis reaches 70°C,
	power to the cards in the chassis is turned off
	automatically. Power is turned on when the
	temperature drops below 60°C.
Operating Environment	Ambient Temperature: 32° to 122° F (0° to 50°C)
	Relative Humidity: 15% to 90% non-condensing
	Shock and vibration sufficient to withstand normal
	shipping
