Table 2.3 defines the jumpers (JB1 - JB11) on the CHAMP-AV8 that reside at the front of the
board near the LEDs (see Figure 2.2 on page 2-8). Jumpers are available for selecting various
board operational modes. Jumpers identified as Reserved must be left in the default setting
and only changed under the direction of Customer Support.
Note:
See the CHAMP-AV8 BIOS User’s Manual for additional information describing the various
boot modes.
Warning
Please make sure that the board is not powered on when configuring board
jumpers and that you observe proper static control procedures when handling the
card.

Prevents CHAMP-AV8 from asserting System
Reset during power-on reset.
If the CHAMP-AV8 is declared the System Con-
troller (SYSCON), this setting will have no effect
- the CHAMP-AV8 will still be able to assert Sys-
tem Reset (as required by VITA 46.0).
Allows the CHAMP-AV8 to assert System Reset
during power-on reset, as permitted by
ANSI/VITA 46.0, Permission 4-11.

Cross Reference
A Rear Transition Module (RTM) is available for the CHAMP-AV8, that provides an alternative
method of configuration control through the manipulation of specific backplane interface
control signals. See “Rear Transition Module (RTM) Configuration Switches” on page A-57
for details.
