    JCI

    We have a customer, who has NC350 with OSW and DX9100, UNT, etc.. This site is 15 or so years old.
    I my question is if the OSW dies, do we have to change all UNT, DX9100, etc.. out?

    Don't measure, don't care. These boxes temperatures NEVER rise to -37 degrees in the past 2 years that I work on them. Stay around -40 to -41
