• VCC_FMC_VIOB is a supply output from the FMC card.
• Only one source for each I/O voltage VCC_IO_A, VCC_IO_B or VCC_IO_C is allowed.
• The factory default jumper settings are 1-2, 7-8, 11-13. As a consequence of these settings, no voltage
is applied to the Mercury module connector, therefore it prevents the module from booting. PWGD
LED will not be lit.
Make sure that the jumper configuration chosen does not short power nets together. The colored pins in
Figure 10 represent power pins. The grey IO_ voltage pins must have a single power source.
To provide power to the VCC_IO_A, B and C pins, tree jumpers are included in the product deliverables.
Please note that not all combinations can be realized with jumpers; wire jumpers can be used instead when
required.

Warning!
Do not merge power pins. Merging power pins can damage the Mercury module or FMC card.
