Table 2–11 lists the board-specific LEDs component references and manufacturing
information.
Setup Elements
The development board includes several different kinds of setup elements. This
section describes the following setup elements:
■ Board settings DIP switch
■ JTAG chain header switch
■ PCI Express control DIP switch
■ Reset configuration push-button switches
Board Settings DIP Switch
The board settings DIP switch (SW4) controls various features specific to the board
and the MAX
II CPLD EPM2210 System Controller logic design. Table 2–12 shows the
switch controls and descriptions.
D23 10 Green LED. Illuminates to indicate Ethernet linked at 10 Mbps connection speed.
Driven by the Marvell 88E1111 PHY.
D22 100 Green LED. Illuminates to indicate Ethernet linked at 100 Mbps connection speed.
Driven by the Marvell 88E1111 PHY.
D21 1000 Green LED. Illuminates to indicate Ethernet linked at 1000 Mbps connection speed.
Driven by the Marvell 88E1111 PHY.
D6 HSMC Port A
Present Green LED. Illuminates when HSMC port A has a board or cable plugged-in such
that pin 160 becomes grounded. Driven by the add-in card.
D1 HSMC Port B
Present Green LED. Illuminates when HSMC port B has a board or cable plugged-in such
that pin 160 becomes grounded. Driven by the add-in card.
D24 PCIe x1 Green LED. Configure this LED to display the PCI Express link width x1.
D25 PCIe x4 Green LED. Configure this LED to display the PCI Express link width x4.
D26 PCIe x8 Green LED. Configure this LED to display the PCI Express link width x8.
