Coin-cell battery
Your server has a special type of memory that maintains the date, time, and configuration information for
built-in features. The coin-cell battery keeps the information active when you turn off the server. The coin-cell
battery normally requires no charging or maintenance throughout its life; however, no battery lasts forever. If
the coin-cell battery fails, the date, time, and configuration information, including passwords, are lost and an
error message is displayed when you turn on the server.
