1 Introduction
The NAMC-EXT is an extender card for standard AMCs, single width, double height. It
can be plugged onto any ATCA carrier board supporting AMC standards. It is also
designed to meet the requirements of μTCA systems.
It eases debugging of AMC boards by enabling the user to access the module under test
from both sides, install debug port cables, and allow access for measurement of power
supplies.
Please note: As an assembly option the board can be equipped with an on-board +3.3V
power supply for generating +3.3V Management Power from +12V Payload Power, so the
module under test can be operated with an external +12V power supply only (NAMC-
EXT-PS).
For reasons of simplification this manual refers to the notation NAMC-EXT if common
functionality is described. If the behaviour differs on the variants, differences are
described for each variant separately.
The following figure shows a photo of the NAMC-EXT. It is equipped with two AMC-
Connectors; one on the rear side to connect to the backplane of the chassis and the
other one – surrounded by a guide rail – for insertion of the front AMC.

2 Overview
The NAMC-EXT is a passive extender board, it does not contain any circuitry. The
NAMC-EXT-PS features an on-board +3.3V power supply for generating Management
Power from Payload Power, so the module under test can be operated with an external
+12V power supply only.
2.1 Block Diagram
The following figure shows a block diagram of the NAMC-EXT-PS with the optional
power supply.

2.2 Location Diagram
The following figures highlight the position of the important components. Depending on
the board type it might be that the board does not include all components named in the
location diagrams. This applies in particular to the optional +3.3V power supply of the
NAMC-EXT-PS.

2.3 Dimensions
The main function of the NAMC-EXT is to allow access for measuring and debugging
purposes to a standard AMC. Hence connector JP1 (that picks up the AMC) and all
measuring points are located on the extended part outside the chassis.
To allow this it is inevitable that the extended area varies from the outlines defined in the
AMC.0 specification, whereas the part that fits into the chassis still complies with the
defined dimensions. Figure 6:The following figure shows the dimensions of the NAMC-
EXT.

3 Board Features
3.1 Bus Interface
x All AMC ports connected
3.2 Power Supply
x The NAMC-EXT draws very little power from the carrier supplies. Current drawn from
+3.3V and +12V is less than 10mA each.
x Power planes for GND, payload power and management power.
x Both power supplies drive signalling LEDs.
x Both power supplies may be cut by opening wire bridges for current measurements.
x On the NAMC-EXT-PS +3.3V Management power may either be taken from the
backplane or generated locally from Payload Power (assembly option).
x Payload Power may either be taken from the backplane or a +12V power supply may
be connected to wire bridge BR4.

4.2 Connectors, Jumpers and Wire Bridges
There are 2 connectors and 3 wire bridges on the NAMC-EXT. Connector J1 is a direct
connector and fits into the ATCA or PTCA AMC slot. Connector JP1 is the socket into
which the device under test is plugged. The figure below shows the connectors, as well
as the wire bridges:

4.2.2 Jumper JP2
The setting of jumper JP2 defines the source for /AMC_ENABLE signal. The default
position (right aligned) means the signal is connected to the backplane. In the left
aligned position the signal is pulled down locally on the extender board.
4.2.3 Jumper JP3 (NAMC-EXT-PS only)
The setting of jumper JP3 defines the source of Management Power. By default,
Management Power is taken from the backplane (jumper JP3 in the upper
position). In case there is no Management Power available (e.g. a test assembly
with just a +12V supply), Management Power can be generated on-board from
the +12V Payload Power. In order to make use of this feature, set jumper JP3 to
the lower position.
Upper position:
Management Power taken
from backplane
Lower position:

generated locally
Please note: The function of Jumper JP3 is only valid on the NAMC-EXT-PS.

NAMC-EXT – Technical Reference Manual
Version 1.6 © N.A.T. GmbH 20
4.2.4 Wire Bridges
The wire bridges BR1 and BR2 connect the supply voltages. The supply current
can be measured between both contacts of one bridge if the respective wire
bridge is opened.
Please note: Instead of using a simple ampere meter it is recommended to insert
a shunt resistor (e.g. 10 mΩ) between the contacts and measure the voltage drop
to calculate the current or to monitor it on an oscilloscope.
Both contacts of BR3 are connected to ground; it can be used as a reference
contact for measuring and/or to connect an external power supply (NAMC-EXT-
PS only).
Both contacts of BR4 are connected to +12V Payload Power; it can be used to
connect an external power supply to the extender board (NAMC-EXT-PS only).
The following table gives an overview of the wire bridges and the supplies they
connect.

4.3 Test points
There are a number of test points available on the NAMC-EXT. Due to layout reasons
there are only small SMD test points for the differential signals. All other signals (e.g.
geographical address, IPMB signals, etc.) are routed to standard test points, into which
standard 100 mil header connectors may be assembled. By default, there are no headers
assembled. The names of the signals carried by the test points are printed on the
silkscreen.
