3.6 PCI Mezzenine Card (PMC) Installation
The PMC slots are designed as 5V and / or as a universal PCI interface. The
PMC sites are keyed to prevent users from installing a 3.3V only PMC
module.
The rear I/O signals on the J14 of the upper PMC slot are routed to J3 of the
6810/6820 main-board. Refer to section 2.3.15 and 2.3.17 for detail PMC
I/O signal routing. If a HDD is mounted to the main board, the HDD will
occupy the upper PMC slot #1.

Step 1: Prepare an ESD protected area including an anti-ESD table and
ESD strap. Attach the ESD strap to your wrist and connect the end
of the ESD strap to ground of the anti-ESD table.
Step 2: Remove the PMC panel from the front panel.
Step 3: Install the PMC module on to the PMC sockets.
Step 4: Screw the PMC mounting bolts to the main board from the bottom
side up to fix the PMC module in place.
3.7 RTM Installation
This section describes important information regarding the use of the rear I/O
connections. Refer to section 2.4 for peripheral connectivity of all I/O ports
on the RTM. When installing the cPCI-6820 and its RTM, make sure the
RTM is the correct model that matches its front board.
0 Use the correct RTM to enable functions (I/O interfaces) on rear side.
The RTM or system board can be damaged if the incorrect RTM is used.
Some I/O ports are supported on both the front board and the RTM, including
Keyboard, Mouse, VGA and USB. These I/O ports can be connected either
via the front or rear modules but DO NOT access these ports on both front
and rear simultaneously.
