Harrier Power Up Configuration Header
A 2 mm, 8-pin low profile header located on side 1 of the CPCI-6020 provides the means to
change some of the Harrier power up configuration settings. The pin assignments for this
header, along with the power up setting with the jumper on or off, are as follows (boards are
shipped with all jumpers off):
2.8.3
PMC 66 MHz Disable
This 0.1 inch, 2-pin header (J21) located on the CPCI-6020 is used to disable 66 MHz
operation on PCI Bus B. When a jumper is installed between pins 1 and 2, PCI Bus B will
operate at 33 MHz regardless of whether the PMC is capable of 66 MHz. This prevents the
secondary Ethernet controller from being disabled if a 66 MHz capable PMC is installed. The
jumper pulls the M66EN signal low so the PMC can be aware that the bus is operating at 33
MHz.
2.8.4
Enable/D12 V and -12 V Use
This 0.1 inch, 2-pin header (J18) located on the CPCI-6020 is used to d/-12 V on the
board.
