Power Calculation
For the ONS 15454 M6 shelf that is powered by the 15454-M6-DC20 or the 15454-M6-DC40 power module,
the controller card calculates the total power consumption of the shelf, which is displayed in the Provisioning
> General > 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. Refer to the
Power Requirements
calculation.
The Actual Power is the power consumed by a line card once it has boot-up. The Typical Power is the power
consumed by a line card when it is physically present in the shelf but deleted in CTC, or when it has not
boot-up due to PWR-CON-LMT alarm after installation or pre-provisioning.
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 causes the PWR-CON-LMT alarm.
