Power Allocation
Power Limit Operation	96
Module Power Allocation	97

	This chapter discusses the power allocation function.
	For the majority of Agilent N6700 Modular Power System
	configurations, full power is available from all installed power
	modules. However, it is possible to configure a power system in
	which the combined ratings of the power modules exceed the power
	rating of the mainframe.
	The power rating of Agilent N6700 mainframes is as follows:
	Agilent N6700A/B = 400 W
	Agilent N6701A = 600 W
	Agilent N6702A @ nominal 100 - 120 VAC = 600 W
	@ nominal 200 - 240 VAC = 1,200 W
	Note that the power system will continue to operate normally as long
	as the combined module output power is within the power rating of
	the mainframe.
	The power allocation function is only available on power system mainframes
NOTE
	with firmware revision C.00.00 and up. To upgrade your power system with the
	latest firmware revision, go to http://www.agilent.com/find/N6700firmware.
	If this firmware is not installed, the later higher-power modules will not be
	recognized by the mainframe and a self-test error will result.
