4.2.10 LD13 - 5V Power Indicator
The
green
LED, LD13, indicates a 5V power level on the MPC8349E MDS Processor Board.
A 5V power supply is plugged into the P11 Power Connector on the board's front side for the
Stand-Alone Mode. The MPC8349E MDS Processor Board is powered by the 5V external power
supply when the SW5 Power Switch is turned to the "ON" (up) position.
When the MPC8349E MDS Processor Board is plugged into an PC via the PCI edge connector it
is powered from the edge connector's 5V power rail (Agent Mode). In the PIB Combined Mode,
5V power is supplied from the PIB's power supply via risers connectors. Note that if working in
either of these two modes, the position of SW1 is ignored.
