Product Description 1.8 Real-Time Clock Subsystem A coin-cell battery (CR2032) powers the real-time clock and CMOS memory. When the computer is not plugged into a wall socket, the battery has an estimated life of three years. When the computer is plugged in, the standby current from the power supply extends the life of the battery. The clock is accurate to ± 13 minutes/year at 25 ºC with 3.3 VSB applied via the power supply 5 V STBY rail. NOTE If the battery and AC power fail, date and time values will be reset and the user will be notified during the POST. When the voltage drops below a certain level, the BIOS Setup program settings stored in CMOS RAM (for example, the date and time) might not be accurate. Replace the battery with an equivalent one. Figure 1 on page 13 shows the location of the battery. 1.9 Connectivity 1.9.1 Thunderbolt™ Technology Interface The board's Thunderbolt Technology Interface is supported by an Intel® L3310 CIO 10 Gb Controller. The Thunderbolt controller connects a PC and other devices, transmitting and receiving information for both PCI Express and DisplayPort* protocols. The Thunderbolt controller switches between the two protocols to support communications over a single cable. Thunderbolt technology is implemented on Intel Desktop Board D33217CK as a plug and play interface. No software drivers are required. 1.10 Hardware Management Subsystem The hardware management features enable the board to be compatible with the Wired for Management (WfM) specification. The board has several hardware management features, including thermal and voltage monitoring.

1.8
Real-Time Clock Subsystem
A coin-cell battery (CR2032) powers the real-time clock and CMOS memory.
When the
computer is not plugged into a wall socket, the battery has an estimated life of three
years.
When the computer is plugged in, the standby current from the power supply
extends the life of the battery.
The clock is accurate to
±
13 minutes/year at 25 ºC
with 3.3 VSB applied via the power supply 5 V STBY rail.
NOTE
If the battery and AC power fail, date and time values will be reset and the user will be
notified during the POST.
When the voltage drops below a certain level, the BIOS Setup program settings stored
in CMOS RAM (for example, the date and time) might not be accurate. Replace the
battery with an equivalent one.
Figure 1 on page 13 shows the location of the battery.
