ONS 15454 and AC/DC Converter for 220V

Unanswered Question

I am looking for a AC/DC converter for a ONS15454 for a 220V input.


The ONS 15454 datasheet indicate input current 22A maximum.


The Cisco AC/DC Power Solution datasheet indicate for ONS 15454 a medium solution.


And the same datasheet indicate the small solution is up to 32A for 220V.


Then, can I use the small configuration for ONS at 220V?


Anyone know that? Can you help me with that?

  • Cisco Employee,

What is the hardware configuration of your 15454 including chassis, fan and by slot?


Using the hardware config, you can calcualte the expected amperage.

The general power requirement of 22A provides for any possible configuration. Actual configurations may be less. I have some 454s using as little as 9A in the lab.

Thanks a lot for your answer.


I am using a ONS15454 ANSI with only 3 cards installed.


Probably I will install more cards in the future, and I don?t like to change the AC/DC coneverter later.


But, I 22A provides any possible configuration and AC/DC converter provide 32A at 220V.


Why the datasheet are indicating that I need a medium configuration?


Is the datasheet indicating the configuration for 110V or I am missing something?


Thanks a lot. Graciela.

Could I use

The reason the medium size Cisco AC/DC system is recommended for the Cisco15454 is due to the fusing. The medium system has 30amp breakers via the expansion panel (included with a medium config). A small AC/DC system will only have GMT fuses, which, if memory serves me correctly, are only available up to 15amps. So, to future proof your installation, a medium should be the answer.
