TCC card on 15454

Does this card have an internal battery?

Will it keep the current time if the shelf experiences a complete loss of power?

It could have internal battery. Internal timing is not intended for use as the primary timing source during normal operation. Cisco recommends that you use a higher quality source (preferably Primary Reference Source/Primary Reference Clock (PRS/PRC) clocks) for primary network timing with the internal clock available for times when all other timing sources fail.

I understand about timing, I am asking about time and date information.

Thanks,

If you are using SNTP server, it will automatically update the time and date information, else, yes it will retain the time, but will be offset by the time it was down.
