elements.
Table 2–8 lists the LED board references, names, and functional descriptions.
Table 2–8. Board-Specific LEDs
Board Reference LED Name Description
D1 PSNTN A
Green LED. Illuminates when the HSMC port A has a board or cable
plugged-in such that pin 160 becomes grounded. Driven by the add-in
card.
D2 PSNTN B
Green LED. Illuminates when the HSMC port B has a board or cable
plugged-in such that pin 160 becomes grounded. Driven by the add-in
card.
D11 POWER Blue LED. Illuminates when 3.3-V power is active.
D16 FPGA_CONF_DONE
Green LED. Illuminates when the FPGA is successfully configured. Driven
by the MAX II CPLD EPM2210 System Controller.
D17 FAN
Red LED. Illuminates when the FPGA needs to use the fan and heatsink.
Driven by the MAX II CPLD.
D18 MAX_ERROR
Red LED. Illuminates when the MAX II CPLD EPM2210 System Controller
fails to configure the FPGA. Driven by the MAX II CPLD EPM2210 System
Controller.
D19,
D20,
D21
PROGRAM
MAX_EPCS
MAX_USER
MAX_FACTORY
Green LEDs. Illuminates to show the LED sequence that determines
which flash memory image is loaded to the FPGA. The image to be loaded
depends on the selection of the three LEDs. Driven by the MAX II CPLD
EPM2210 System Controller.
D22 USB
Green LED. Illuminates when the embedded USB-Blaster is in use to
program the FPGA. Driven by the MAX II CPLD EPM2210 System
Controller.
D24 1000
Green LED. Illuminates to indicate Ethernet linked at 1000 Mbps
connection speed. Driven by the Marvell 88E1111 PHY.
D25 100
Green LED. Illuminates to indicate Ethernet linked at 100 Mbps
connection speed. Driven by the Marvell 88E1111 PHY.
D26 10
Green LED. Illuminates to indicate Ethernet linked at 10 Mbps connection
speed. Driven by the Marvell 88E1111 PHY.
D27 DUP
Green LED. Illuminates to indicate Ethernet in full-duplex operation.
Driven by the Marvell 88E1111 PHY.
D28 PCIE_LED_X1
Green LED. Illuminates to indicate PCIe connection with channel width of
×1. Driven by the FPGA.
D29 PCIE_LED_X4
Green LED. Illuminates to indicate PCIe connection with channel width of
×4. Driven by the FPGA.
D30 ENET TX
Green LED. Illuminates to indicate Ethernet PHY transmit activity. Driven
by the Marvell 88E1111 PHY.
D31 ENET RX
Green LED. Illuminates to indicate Ethernet PHY receive activity. Driven
by the Marvell 88E1111 PHY.
