5.5 PCI Mezzanine Card (PMC) Installation
The PMC slot is designed to support 3.3V and 5V V(I/O), and the
default setting is 3.3V. Before you install the PMC module on the
cPCI-6965, please make sure that the PMC V(I/O) jumper JPX1
has been correctly set (see “PMC V(I/O) Select Jumper (JPX1)”
on page 47).
1. There is a 3.3V key on the DB-6965PMC by default, if
the PMC module you wish to install is 5V signaling,
please switch the key to the 5V location and set the PMC
V(I/O) jumper JPX1 to the 5V setting.
2. Attach the DB-6965PMC adapter board onto the PMC
module as shown.
