PCZ-NVM w. CPU Card (Picture Similar)
General Information
Available as a mezzanine add-on expansion
board (aka side card) e.g. to the PC7-FESTIVAL
CompactPCI® PlusIO CPU, the PCZ-NVM is
equipped with two M.2 SSD module sockets,
asaruggedmassstoragesolution.Inaddition,
frequently required I/O functions (RS-232,
USB 3.0, DisplayPort) are provided via front
panel connectors.
Both M.2 sockets are suitable for PCIe® based
SSD modules (M-key) up to the 2280 format.
TheupperconnectorestablishesaPCIe®Gen3
link x4 or will be automatically switched to
SATA mode for a legacy SSD. The lower
connector M.2 socket supports a PCIe® Gen3
link x2.

Technical Information • PCZ-NVM • CPU Expansion Side Card
System Requirements
The PCZ-NVM is a mezzanine side card, to be
fixed on top of a suitable CPU carrier board.
ThepitchbetweencarrierPCBandmezzanine
PCB is 4HP, resulting in a 8HP common front
panel for the entire assembly.
Twomezzanineinter-boardconnectorsarein
use, for distribution of high speed I/O signals
from the CPU carrier to the side board. These
are referred to as HSE1 (PCIe® x4 and USB3
High Speed Expansion), and HSE2 (PCIe® x4
and DisplayPort). The mezzanine connectors
are situated on the bottom side of the
PCZ-NVM, facing towards their mating CPU
card connectors.
For full functionality, suitable CPU carrier
boards must conform to the EKF '2017 New
Mezzanine Concept' (i.e. HSE1 and HSE2
connectors supported).
The PCZ-NVM also is a carrier board itself,
which can accommodate a 3rd floor front
panel I/O expansion card, as an option.
The PCZ-NVM is basically powered via its HSE
mezzanineconnectors.Inaddition,theboard
is equipped with the backplane connector J1
for high power demanding SSDs
(CompactPCI® backplane w. CPU card system
slot left).

Storage Options
ThePCZ-NVMcanbepopulatedwithtwoM.2
(NGFF) PCI Express® driven SSD storage
modules, up to the 2280 size.
Suitable PCIe® x4 SSD modules are provided
with an M-key and conform to the M.2
specification'Socket3'pinout.M.2NVMeSSD
modulesare available up to2TB asof current,
mostly as 2280 type.
The upper socket M1 is wired to the
mezzanine connector HSE1, for a PCIe® Gen3
x4 link, resulting in a theoretical maximum
bandwidth of 32Gbps, or SATA lane (6Gbps).
The lower M.2 connector M2 is controlled by
a x2 link, established via the HSE2 mezzanine
connector, for a maximum data transfer rate
of up to 16Gbps.

PCZ-NVM w. C32-FIO
Front Panel I/O
The PCZ-NVM expands the suite of front
panel connectors of the CPU carrier board by
an USB 3.0 receptacle, a DisplayPort video
output, and two D-Sub connectors with
EIA-232 signal level COM port pin
assignment.
In addition, the PCZ-NVM can accommodate
the C32-FIO front panel I/O mezzanine
module,foratotalfrontpanelwidthof12HP.
The C32-FIO provides another two RS-232
COM ports, and an USB 2.0 receptacle.

Installing and Replacing Components
Before You Begin
Warnings
The procedures in this chapter assume familiarity with the general terminology associated with
industrial electronics and with safety practices and regulatory compliance
required for using and modifying electronic equipment. Disconnect the
systemfromitspowersourceandfromany telecommunication links, networks or
modems before performing any of the procedures described in this chapter.
Failure todisconnect power, or telecommunicationlinks beforeyouopenthesystemor perform
anyprocedurescanresult inpersonalinjuryorequipmentdamage.Somepartsofthesystemcan
continue to operate even though the power switch is in its off state.
Caution
Electrostatic discharge (ESD) can damage components. Perform the procedures
described in this chapter only at an ESD workstation. If such a station is not
available, you can provide some ESD protection by wearing an antistatic wrist
strapandattachingittoametalpartofthe system chassis or board front panel. Store
the board only in its original ESD protected packaging. Retain the original packaging (antistatic
bag and antistatic box) in case of returning the board to EKF for repair.
