Installation

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.
