Board Reference LED Name Description
D24 POWER Blue LED. Illuminates when 3.3-V power is active.
D5 CONF DONE
Green LED. Illuminates when the FPGA is successfully configured. Driven by the
MAX II CPLD EPM2210 System Controller.
D26 Loading
Green LED. Illuminates when the MAX II CPLD EPM2210 System Controller is
actively configuring the FPGA. Driven by the MAX II CPLD EPM2210 System
Controller wire-OR'd with the Embedded Blaster CPLD.
D27 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.
D35 ENET TX
Green LED. Blinks to indicate Ethernet PHY transmit activity. Driven by the Marvell
88E1111 PHY.
D34 ENET RX
Green LED. Blinks to indicate Ethernet PHY receive activity. Driven by the Marvell
88E1111 PHY.
D33 100
Green LED. Illuminates to indicate Ethernet linked at 100 Mbps connection speed
Driven by the Marvell 88E1111 PHY.
D32 1000
Green LED. Illuminates to indicate Ethernet linked at 1000 Mbps connection speed.
Driven by the Marvell 88E1111 PHY.
D1
HSMC Port A
Present 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
HSMC Port B
Present 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.
D30 MUTE Green LED. Illuminates when the SDI receiver carrier detect is active.
D40 FAN LED
Green LED. Illuminates when a heat sink or fan should be installed. Driven by the
MAX1619 thermal sensor OVERTEMPn signal.
