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.
