When you turn off the workstation through the operating system, power consumption falls below what is
considered low power consumption but does not reach zero. This low power consumption feature extends the
life of the power supply.
System board
If you replace the system board:
●
Make a note of the cable connections before disconnecting them from the system board.
●
Follow good cable management practices. See
The following tables show system cabling for the workstations.
