Lithium bettery in ASA 5510

1. Hi all,

There is a BR2032 lithium battery in my ASA 5510. Can you anyone explain what it's used for? Is it critical?

Thank you

I believe that this is the PRAM battery, used for supplying power to the clock on the ASA. This is critical to save the clock of the ASA during reloads.
