Note	1.	If power supply specifications cannot be met with a single power supply when the current ca-
		pacity of the Thick Cable exceeds 8 A even after the power supply location is modified, use
		more than one communications power supply.
Note	2.	In configuration 1, the power can be supplied in two directions to the trunk line as long as the
		current capacity of each is 8 A or less when using Thick Cable, i.e., it is possible to have a
		configuration with a total maximum current capacity of up to 16 A.
