ABORT# Switch
The ABORT# switch is recessed to reduce the likelihood of accidental activation. The ABORT#
signal is connected to the Harrier Abort Switch (ABTSW_L) input and generates an MPIC
internal interrupt. This signal is debounced in the Harrier ASIC.
3.3.5
RESET# Switch
The RESET# switch is recessed to reduce the likelihood of accidental activation. The signal is
connected to the Harrier Reset Switch (RSTSW_L) input which will generate a Harrier Reset
Out, which is ORed with the board reset logic. This signal is debounced in the Harrier ASIC.

Front Panel LEDs
The CPCI-6020 provides these LEDs on the front panel. Refer to the Harrier Application
Specific Integrated Circuit (ASIC) Programmer's Reference guide for details of the BDFL bit.

pin assignments for connectors J3, J4 and J5 apply to the transition module, as well as the
CPCI-6020.
3.4.1
CompactPCI Bus Connectors
The CPCI-6020 implements a 64-bit CompactPCI interface on connectors J1 and J2. Each of
these connectors conform to the CompactPCI specification. The pinout for connectors J1 and
J2 are shown in
J1 is a 110 pin AMP Z-pack 2 mm hard metric type A connector with keying for +3.3 V or
+5 V
J2 is a 110 pin AMP Z-pack 2 mm hard metric type B connector
