Components and Interfaces
November 2011 Altera Corporation Transceiver Signal Integrity Development Kit,
Stratix IV GT Edition Reference Manual
Table 219 lists the fan control jumper (J64) which configures the fan.
An over-temperature orange warning LED (D6) also connects to the FPGA to indicate
that an over-temperature condition exists and that a fan should be attached and
running. Table 220 lists the pin-out of the temperature sense interface to the FPGA.
Table 221 lists the temperature
sensor component reference and manufacturing
information.
Table 2–19. Fan Control Jumper (J64)
Board Reference Jumper Name Description
J64 FAN
When jumper is installed on pins 1-2, the fan is auto-controlled by the FPGA.
When jumper is installed on pins 2-3, the fan is always on.
