3.5.4.4 Triple Chassis Power Considerations
The Triple Chassis receives its power from the UPS through the supplied 24 VDC universal
adapter. The total current required by your management products
must not exceed the 850 mA
limit of the power adapter. See “Determining power requirements”.
3.5.4.5 Determining Power Requirements
To determine the total amount of current required by your management products, add the
individual current requirements for each management product to be installed with the APC
BC300 Triple Chassis to the current requirements of the chassis itself.
