Real-Time Clock
The server board has a time-of-day clock and 100-year calendar. A battery on the board keeps the
clock current when the server is turned off.
USB Support
The server board has four rear panel USB ports. You can connect four USB peripheral devices
directly to the server without an external hub. To attach more than four devices, connect an
external hub to either of the built-in ports. The server board supports the UHCI specification and
takes advantage of standard software drivers written to be compatible with UHCI.
