A.3.11.1 Power Calculation
For the ONS 15454 M6 shelf that is powered by the 15454-M6-DC20 power module, the controller card calculates the total power consumption of the shelf, which is displayed in the Provisioning > Power Monitor tab in CTC. For the power calculation to function properly ensure that:
•There is no MEA alarm on any card.
•The LCD module is properly plugged-in.
The total power consumption value for the shelf is computed by aggregating the power consumption values of individual cards and ancillary units installed or pre-provisioned in the shelf. Table A-4 lists the power consumption values of the line cards that are considered for power calculation.

During power calculation, certain wattage is always reserved for ancillary units like the ECU, fan tray, and standby controller card, irrespective of whether they are present in the shelf or not. The reserved power for the ONS 15454 M6 shelf with a TNC or TNC-E controller card is 284 W, and for the TSC or TSC-E controller card it is 270 W.
Note In the shelf powered by the15454-M6-DC20 power module, a new line card will not boot if it causes the power consumption of the shelf to exceed 960 W. The PWR-CON-LMT alarm is raised in the Alarms tab in CTC when the installation or pre-provisioning of a card causes the power consumption to exceed 960 W. You must uninstall and deprovision the card that caused the PWR-CON-LMT alarm.
