CPU Board
Overview
The PC2-LIMBO is a low power 4HP/3U
CompactPCI
®
CPU board, equipped with an
Intel® Atom™ E6xx series 1.6GHz processor, available on request for the industrial operating temperature range. The PC2-LIMBO front panel is provided with two Gigabit Ethernet jacks, two
USB receptacles, and a DVI video connector for attachment of a high resolution digital display.
The PC2-LIMBO is equipped with up to 2GB soldered RAM for rugged applications. An onboard CFast™ host connector is provided for attachment of a SATA SSD module. In addition, a microSD card holder can accommodate an industrial microSDHC Flash card. Further more, several SATA based low profile mass storage expansion modules are available as an option.
The PC2-LIMBO is equipped wit a set of local expansion interface connectors, which can be optionally used to attach a mezzanine side board. A variety of expansion cards is available, e.g. providing legacy I/O (e.g. RS-232) and additional PCI Express® based I/O circuitry such as SATA, USB and Gigabit Ethernet. Most mezzanine side cards can accommodate in addition a 2.5-inch drive.
Typically, the PC2-LIMBO and the related side card would come as a readily assembled 8HP unit. As an alternate, low profile mezzanine storage modules are available that fit on the
PC2-LIMBO while maintaining the 4HP profile.
The C42-SATA module e.g. is provided with a
1.8-Inch Micro SATA SSD up to 800GB capacity.
CompactPCI® PlusIO (PICMG 2.30) is a new standard for rear I/O across J2, specified by the
PICMG®. High speed signal lines (PCI Express®,
SATA, Gigabit Ethernet and USB) are passed from the PC2-LIMBO through the special UHM connector to the backplane, for usage either on a PlusIO rear I/O transition module, or
CompactPCI® Serial card slots.
CompactPCI® Serial (PICMG CPCIS.0) defines a completely new card slot, based on PCI
Express®, SATA, Gigabit Ethernet and USB serial data lines. On a hybrid backplane, both card styles can reside, CompactPCI® and
CompactPCI® Serial, with the PC2-LIMBO in the middle as system slot controller for both backplane segments.

Microprocessor
The PC2-LIMBO is equipped with an Intel® Atom
TM
E6xx processor (code name Tunnel Creek). These low power processors provide integrated graphics and memory controller, which results in a very efficient platform design. The E6xx almost can be considered as a single-chip solution, since all functions of a typical north-bridge have been moved to the CPU, as well as some I/O circuitry of a typical south-bridge.
There is no proprietary chipset expansion interface provided with the E6xx processor. Instead, additional I/O can be attached to four ordinary PCI Express® lanes. The PC2-LIMBO is equipped with several PE based I/O controllers, e.g. SATA and Ethernet, and the EG20T PCH (Platform Controller
Hub) for multi-function I/O.
As of current, the Atom
TM
E6xx family comprises processors from 0.6GHz up to 1.6GHz core frequency, either commercial or industrial temperature grade, as listed below. The processors are housed in a FCBGA package for direct soldering to the PCB, i.e. the chip cannot be removed or changed by the user.

Thermal Considerations
The PC2-LIMBO is equipped with a low profile passive heatsink for fan-less conductive cooling, thus maintaining the 4HP envelope of a typical CompactPCI® card. In many situations a forced vertical airflow through the system enclosure (e.g. bottom mount fan unit) may be not required, due to the low power consumption of the Atom
TM
E6xx series, but should be considered to further improve the reliability and life-time of the assembly unit, especially for higher ambient temperatures.
The table above (Intel® Atom
TM
Processors Supported) indicates the calculated maximum power consumption (TDP = Thermal Design Power) of a particular processor. According to experience, the
CPU power consumption is significantly lower when executing typical Windows® or Linux tasks.
The Atom
TM
E6xx processors provide thermal based Enhanced SpeedStep® technology. This enables dynamic switching between multiple core voltages and frequencies depending on core temperature and currently required performance. The processors are able to reduce their core speed and core voltage in multiple steps. This leads to an additional reduction of power consumption, resulting in less heating. This mode of lowering the processor core temperature is called Thermal Monitor 2.
Another way to reduce power consumption is to modulate the processor clock (Thermal Monitor 1 mode). When this feature is enabled and the die temperature is reaching the pre-determined activation temperature, the processor clocks are stopped for a period of time and then allowed to run full speed for a period of time (duty cycle ~30% – 50%) until the processor temperature drops below the activation temperature. However, while saving considerable power consumption, the data throughput of the processor is also reduced.
The temperature at which the on-die thermal sensor triggers the Intel® Thermal Monitor 1 or Intel®
Thermal Monitor 2 is set during the fabrication of the processor (can be read-out by software).
The thermal management features are enabled under BIOS control (please observe related BIOS menu entries). By default the BIOS of the PC2-LIMBO enables the Thermal Monitor 2 mode which is the most efficient.

Main Memory
The Atom
TM
E6xx processor is equipped with an internal memory controller, suitable for a maximum capacity of 2GB DDR2, operated at 800MHz. The memory controller supports only soldered-down
DRAM (no SODIMM).
The PC2-LIMBO is provided with either 1GB or 2GB memory, organized as 8 devices 1Gbit or 2Gbit each, soldered directly to the board (Memory Down). Please consider your actual need for a sufficient memory capacity before ordering.
Graphics Subsystem
The Intel® Atom™ Processor E6xx series provides an integrated 2D/3D graphic engine that performs pixel shading and vertex shading within a single hardware accelerator. The processing of pixels is deferred until they are determined to be visible, which minimizes access to memory and improves render performance. In addition, the E6xx series supports video decoding (MPEG2, MPEG4, VC1,
WMV9, H.264, and DivX), and also encoding (MPEG4, H.264).
The PC2-LIMBO is provided with a DVI-D (digital video interface) front panel connector attached to the E6xx SDVO port via a PanelLink transmitter, for a maximum resolution up to 1920x1080.
Known issues: As of current, Intel® Embedded Graphics Drivers for the Atom™ Processor E6xx series must be used together with Windows 7. Ubuntu may not work as expected with respect to the graphics interface. Video decoding with Linux may be slow.

LAN Subsystem
The Ethernet LAN subsystem provided on the PC2-LIMBO is comprised of two independent Gigabit
Ethernet ports. Both Ethernet ports are wired to correspondent RJ45 jacks located in the front panel, but can be also managed for usage through the rear I/O interface on J2/P2, on an individual base by
BIOS settings. Two bicoloured LEDs integrated into each RJ45 connector in the front panel are used to signal the LAN link, the LAN connection speed and LAN activity status of the related Ethernet port, regardless whether it is routed to the front panel jack or to the backplane connector J2 for rear I/O.
There are two different Ethernet controllers populated on the PC2-LIMBO board; while port 1 is associated with the Platform Controller Hub, port 2 is realized with additional PCI Express® based silicon. This is the reason why both Ethernet ports offer slightly differing features.
The Platform Controller Hub EG20T (PCH, formerly named Topcliff IOH) contains a Gigabit Ethernet
Media Access Controller (GMAC), which is connected to an external RGMII PHY (Reduced Gigabit
Media Independent Interface) for 1000 BASE Ethernet. The PC2-LIMBO employs the Marvell
88E1116R Gigabit Ethernet Transceiver, which in turn is wired across a signal switch (under BIOS control) either to the upper RJ45 front panel Ethernet jack, or to J2 according to the CPCI 2.30 PlusIO standard. The maximum Jumbo frame size of the PCH EG20T is 10kB.
For the second Ethernet port the Intel® 82574IT GbE controller was chosen, which provides an integrated PHY and many built-in high performance features such as 802.1as TimeSync. It is wired across a signal switch (under BIOS control) either to the lower RJ45 front panel Ethernet jack, or to J2 according to the CPCI 2.30 PlusIO standard. The maximum Jumbo frame size of the 82574 is 9kB.

Serial ATA Interface (SATA)
The PC2-LIMBO provides up to six 3Gbps serial ATA (SATA) ports, derived from three independent
SATA ressources.
The EG20T Platform Controller Hub (PCH) is provided with an integrated SATA two-port controller.
One of these ports is in use for the CFast™ host connector, the other is routed to first SATA port of the mezzanine card connector J-HSE (High Speed Expansion). Only these two SATA channels are suitable for attachment of a SATA boot medium.
Another two PCI Express® based SATA controllers (JMB362, dual-channel each) are populated in addition on the PC2-LIMBO. By default these channels are connected for rear I/O usage to the J2
PlusIO backplane connector, resulting in a maximum of 4 SATA channels for backplane usage (e.g.
hybrid backplane in a CompactPCI® Serial system). As an ordering option, two SATA ports can be
and 3 rd wired instead to the mezzanine connector J-HSE, as the 2 nd
SATA port, which allows use of the C47-MSATA mezzanine storage module. As of current, the BIOS does not contain boot code for these dedicated SATA controllers. SATA boot therefore is possible either from the Cfast™ card, or from mezzanine storage modules such as the C42-SATA, which use the PCH bound 1 st
SATA channel of the J-HSE connector. The additional SATA controllers are not available with the CompactPCI®
Classic manufacturing option of the PC2-LIMBO.
A LED named HD located in the front panel, signals disk activity status of any of the SATA devices.
The CFast™ host connector accommodates a modern Flash based Solid State Drive (SSD), with dimensions of a CompactFlash card, but SATA based interface. CFast™ cards are available from several manufacturers for the extended (industrial) temperature range, and can also be considered as boot device and system drive in small ruggedized systems.

As an option, the PC2-LIMBO can be equipped with a low profile mezzanine storage card such as the
C42-SATA in addition, with an on-board 1.8-inch Micro SATA SSD, or the C47-MSATA, with two mSATA SSD modules. As of current, both mezzanine alternates offer higher storage capacity compared to a CFast™ card. A low profile mezzanine card can be used with or w/o simultaneously utilizing the CFast™ on-board card, and maintains the 4HP profile of the PC2-LIMBO.
Further more, a variety of side cards is available, suitable for mounting on the PC2-LIMBO in a 4HP
(20.32mm) distance (resulting n 8HP front panel width for the assembly). Some of these side boards can accommodate a SATA drive, e.g. a 2.5-inch SSD. If more than one SATA channel is required for a side card with respect to the J-HSE mezzanine connector, the PC2-LIMBO must not be ordered with
4 SATA channels for backplane usage.
In addition to the EG20T PCH with its two SATA ports, two JMicron JMB362 dual-channel SATA controllers are stuffed on the PC2-LIMBO. Depending on the SATA channel in use, either Intel® SATA drivers for the EG20T have to be installed, and/or SATA drivers from the JMicron website.

Please note, that the CompactPCI® Classic version of the PC2-LIMBO does not provide the PCIe packet switch, and consequently will not be equipped with the JMB362 SATA controllers.
Universal Serial Bus (USB)
The EG20T (Topcliff) PCH supports a maximum of six USB 2.0 host ports. Since this would be insufficient for a CompactPCI® CPU card, the PC2-LIMBO is equipped with two on-board 1:4 USB hubs in addition, for an adequate quantity of USB ports available:

EKF offers a variety of mezzanine expansion boards (side cards), to be attached on top of the
PC2-LIMBO, thus typically resulting in a assembly unit with 8HP or even 12HP common front panel.

Real-Time Clock
The Atom™ E6xx processor is equipped with a time-of-day clock and calendar. Battery backup is provided by a BR2032 Lithium Carbon monofluoride coin cell. The battery is suitable for the extended operating temperature range (-40°C to +85°C). Under normal conditions
1
, replacement of the battery should be superfluous during lifetime of the board. In applications were the use of a battery is not permitted, a SuperCap (double layer capacitor, gold cap) with 1.0F capacity can be stuffed instead of the battery, sufficient for ~6h data retention.
1
Due to a known issue of the E6xx processor, the BR2032 battery lifetime may be significantly
reduced, down to ~1 year as a worst case scenario. As of current Intel® classifies the status of this erratum as ‘no fix’. Since the battery will be discharged only when power is disconnected from the
CPU card, lifetime in typical industrial applications may not be affected (24h continuous-running operation in mind).
SPI Flash
The BIOS is stored in flash device with Serial Peripheral Interface (SPI). 8MByte of BIOS code and user data may be stored nonvolatile in this SPI Flash.
The SPI Flash contents can be updated by a DOS or Linux based tool. This program and the latest
PC2-LIMBO BIOS binary are available from the EKF website. Read carefully the enclosed instructions.
If the programming procedure fails e.g. caused by a power interruption, the PC2-LIMBO may no more be operable. In this case you would possibly have to send in the board, because the Flash device is directly soldered to the PCB and cannot be changed by the user.

Reset
The PC2-LIMBO is provided with several supervisor circuits to monitor supply rails like the CPU core voltage, 1.5V, 3.3V or 5V. This circuitry is responsible also to generate a clean power-on reset signal.
The handle within the front panel contains a micro switch that is used to generate a power button event. By pressing the handle's red push button a pulse is triggered.
Animated GIF: www.ekf.com/c/ccpu/img/reset_400.gif
NOTE: To prevent the board to cause a power button override, the handle should be closed immediately after unlocking the front panel handle. A power button override is triggered by opening the front panel handle for at least 4 seconds, which results in bringing the board to power state S5.
In case of entering this state, unlock and lock the front panel handle a 2 nd
time to reenter normal power state S0 again. See also section 'PG (Power Good) LED' to see how the PC2-LIMBO indicates the different power states.
An alternative (and recommended) way to generate a system reset is to activate the signal PRST# located on CompactPCI connector J2 pin C17. Pulling this signal to GND will have the same effect as to push a reset switch.
The healthy state of the PC2-LIMBO is indicated by the LED PG (Power Good) located in the front panel. This bicoloured LED signals different states of the board (see section below). As soon as this
LED begins to lite green, all power voltages are within their specifications and the reset signal has been deasserted.

Sleep state S3, S4 or S5 (S3/S4 deactivated by BIOS as of current, S5 = Soft Off)
Healthy
Red steady Hardware failure
Red blink Software failure
To enter the PG LED state Software Failure, an appropriate service request by software SMI must be called. The PG LED remains in this red blinking state until the next SMI request is made. After that it falls back to its default function.
GP (General Purpose) LED
This programmable bicolour LED can be observed from the PC2-LIMBO front panel. Its status is controlled by the on-board glue-logic (ispMACH 4128). The GP LED is not dedicated to any particular hardware or firmware function with exception of special power states of the LED PG as described above. Nevertheless, a red blinking GP LED is an indication that the BIOS code couldn't start.
The GP LED is provided mainly for user programming, e.g. can reflect the status of dedicated GPIOs under user software control, or any combination of other board internal signals available at the ispMACH programmable logic inputs. Please contact EKF in order to discuss your requirements in detail.
While the CPU card is controlled by the BIOS firmware, the GP LED is used to signal board status information. For details please refer to www.ekf.com/p/pc2/firmware/biosinfo.txt. After successful operating system boot, the GP LED may be freely used by customer software.
HD (Hard Disk Activity) LED
The PC2-LIMBO offers a green LED marked as HD placed within the front panel. This LED signals activity on any device attached to the SATA ports. This includes the EG20T IOH SATA ports as well as the JMicron SATA controllers.
The marking HD denotes a hard disk drive, but needless to say that also activity from solid state drives
(SSD) such as a CFast card would light the HD LED. As previously described, this LED may vary its function dependent on the state of the LED PG.

Hot Swap Detection
The CompactPCI® specification added the signal ENUM# to the PCI bus to allow board hot swapping. This signal is routed to a GPIO (GPIO1 PEX8112 PCIe to PCI bridge) . An interrupt can be requested, if ENUM# changes, caused by insertion or removal of a peripheral board.
Note that the PC2-LIMBO itself is not a hot swap device, because it makes no sense to remove the system controller from a CompactPCI® system. However, it is capable to recognize the hot swap of peripheral boards and to start software that is performing any necessary system reconfiguration.
Power Supply Status (DEG#, FAL#)
Power supply failures may be detected before the system crashes down by monitoring the signals
DEG# or FAL#. These active low lines are additions to the CompactPCI® specification and may be driven by the power supply. DEG# signals the degrading of the supply voltages, FAL# there possible failure. On the PC2-LIMBO the signals FAL# and DEG# are routed to PCH GPIOS.
+5V Only Design
The PC2-LIMBO has been designed for +5V only operation. For system cost reduction, the on-board switching regulator from +5V to +3.3V can be used to feed-back +3.3V through connector J1 to the
CompactPCI® backplane in systems with a single +5V power supply.
The on-board 3.3V switching regulator has been designed for a maximum of 10A load in total. Since the +3.3V rail is shared with on-board components and optional mezzanine cards, the maximum current available for peripheral boards on the CompactPCI® backplane depends on the actual configuration of the PC2-LIMBO. Typically, the PC2-LIMBO would be able to source up to 5A into the backplane +3.3V power rail. This would require a soldered 15A fuse to be populated as an option, placed in series between the on-board +3.3V rail and the backplane connector J1 3.3V pins.
By default, the soldered 15A fuse is not populated. For systems with a dual-rail power supply which provides +3.3V to the CPCI backplane, the fuse should be removed (if populated), in order to avoid a current back-driving situation. Under normal conditions, back-driving +3.3V power from the backplane to the board and vice versa should be permissible, but EKF cannot guarantee this, due to numerous available system power supplies with different characteristics.

Battery Options
By default, the PC2-LIMBO is equipped with a battery holder, which is suitable for a CRB2032 coin type Lithium cell. For rugged applications, a soldered cell may be populated. A third stuffing alternate would be a gold cap.
Coin Cell Holder (Default Stuffing)
Please remove the isolating plastic sheet from the coin cell which may be affixed in order to avoid premature discharge of the battery.
Unfortunately, Intel® describes a severe issue with the battery, which is not expected to be fixed with future versions of the Tunnelcreek processor. There exists a leakage path, which may reduce the typical lifetime of a cell to <1year, when the PC2-LIMBO is not powered (during storage, or when the system is shut down).
The 1.0F rechargable double layer capacitor can be populated as an alternate for such applications, where a battery would not be allowed. Data retention however would be limited to <8h typically.
Low profile C4* mezzanine modules cannot be used when the supercap is stuffed due to its height.
Due to a known issue of the E6xx processor, the BR2032 battery lifetime may be significantly reduced, down to ~1 year as a worst case scenario. As of current Intel® classifies the status of this erratum as ‘no fix’. Since the battery will be discharged only when power is disconnected from the CPU card, lifetime in typical industrial applications may not be affected (24h continuous-running operation in mind).

Most mezzanine expansion modules require an assembly height of 8HP in total, together with the
CPU carrier board (resulting from two cards at 4HP pitch each).
In addition, cropped low profile mass storage mezzanine modules can be attached to J-HSE, which maintain the 4HP envelope, for extremely compact systems. Furthermore these small size modules may be combined with the full-size expansion boards (that means an assembly comprised of 3 PCBs).

CompactPCI
®
®
PlusIO specification defines the usage of rear I/O pins of the 32-bit
system slot for high-speed serial signals. For these high-speed signals a new J2 connector (3M UHM type) has been introduced, which is compatible to the classic 2.0mm hard metric connector J2, and in addition is suitable for high speed differential signals.
The main advantage of the combination of legacy PCI (J1/P1) and modern serial buses on J2/P2 is to realize hybrid backplanes. Hence, the CompactPCI
®
PlusIO standard helps to define a simple migration path from parallel PCI systems to modern serial, point-to-point interconnected systems such as

Replacement of the Battery
When your system is turned off, a battery maintains the voltage to run the time-of-day clock and to keep the values in the CMOS RAM. The battery should last during the lifetime of the PC2-LIMBO
(please note a known E6XX CPU chip issue which is not fixed as of current). For replacement of a soldered Lithium cell, the old battery must be desoldered, and the new one soldered. We suggest that you send back the board to EKF for soldered battery replacement.
Coin Cell Holder (Default Stuffing)
Warning
Option Soldered Lithium Cell
Danger of explosion if the battery is incorrectly replaced or shorted. Replace only with the same or equivalent type. Do not expose a battery to fire.

Local SMB Devices
The PC2-LIMBO contains devices that are attached to the System Management Bus (SMBus). These are the clock generation chip, the SPD EEPROMs for the on-board memory, a general purpose serial
EEPROM and a supply voltage and temperature controlling device in particular. Additional devices may be connected to the SMBus via the CompactPCI backplane signals IPMB SCL (J1 B17) and IPMB SDA
(J1 C17), or pins 29/30 of the mezzanine expansion connector J-EXP.

Beside the continuous measuring of temperatures and voltages the LM87 may compare these values against programmable upper and lower boundaries. As soon as a measurement violates the allowed value range, the LM87 can request an interrupt via the GPE# (General Purpose Event) input of the
Tunnel Creek CPU (which may result in a system control interrupt).

Configuration Jumpers
CMOS Reset (P-GP)
The jumper P-GP may be used to reset the UEFI BIOS configuration to a default state. The UEFI BIOS on PC2-LIMBO stores parts of its configuration values in an area within the BIOS flash, e.g. the actual boot devices. Using this jumper is only necessary, if it is not possible to enter the setup of the BIOS. To reset the settings mount a jumper on P-GP and perform a system reset. As long as the jumper is stuffed the BIOS will use the default CMOS values after any system reset. To get normal operation again, the jumper has to be removed.

Creek CPU). This can be necessary under rare conditions (e.g. battery undervoltage), if the CPU fails to enter the BIOS POST after power on. Note that installing of jumper P-RTC will neither perform the clearing of the CMOS RAM values nor resets the time and date register values of the real time clock.
To reset the RTC core the board must be removed from the system rack. Short-circuit the pins of
P-RTC for about 1 sec. Thereafter reinstall the board to the system and switch on the power. It is important to accomplish the RTC reset while the board has no power. The pin header P-RTC is not stuffed on the PC2-LIMBO by default.

DVI Video Connector
The Intel® Atom™ E6xx Tunnel Creek processor is equipped with an integrated graphics controller, which supports LVDS and SDVO display ports. On the PC2-LIMBO only the SDVO channel is used for video output. The LVDS port is wired to the optional mezzanine connector J-LVDS, for future use on custom specific side cards.
For compatibility with all types of DVI cables, the video front panel receptacle is a DVI-I style connector. However, the connector comprises the digital signals only, which results in DVI-D functionality. The digital video output is derived from the SDVO graphics port of the CPU, via a
PanelLink transmitter.

Ethernet Connectors
The PC2-LIMBO provides two independent Gigabit Ethernet controllers, each with its own MAC address.
The EG20T PCH contains an Ethernet MAC, which is complemented by an additional on-Board PHY, which is wired to the upper RJ-45 Ethernet jack 1 (if not redirected to the PlusIO J2 connector for RIO usage).
The second Ethernet controller is a 82574IT with integrated PHY, which is wired to the lower RJ-45
Ethernet jack 2 (if not redirected to the PlusIO J2 connector for RIO usage).
Both Ethernet ports are routed individually across two-way analog signal switches, for front panel usage, or optional redirection to the backplane connector J2 (for employment on a RIO module such as the PR1-RIO, or utilization on a CompactPCI® Serial backplane). While the front panel Ethernet jacks comprise internal magnetics, the PC2-LIMBO is equipped in addition with discrete magnetics modules for rear I/O.
The direction (front panel or RIO) of either Gigabit Ethernet port is controlled via two processor GPIO lines, which are managed by the BIOS: GPIO_SUS6 switches the Ethernet port 1, and GPIO_SUS5 controls port 2. The default routing is front panel usage. Please adjust the PC2-LIMBO BIOS settings for an alternate configuration.

Mezzanine Connectors & Card Sockets
CFast™ Host Connector CF1
By default, the PC2-LIMBO is provided with a CFast™ host connector. It is suitable for CFast™ cards, which have the same dimensions as CompactFlash™ cards, but are operated in SATA mode. Industrial
CFast™ SSD cards are available up to 64GB as of current. The SATA channel available on the CFast™ socket is derived directly from the Topcliff EG20T PCH. Since SATA based SSD modules are fast and reliable over the industrial temperature range, a CFast™ card can be used as boot device in many applications.
A guiding rail is provided to simplify card insertion. Once installed, the CFast™ card will have to be locked manually by a retainer latch (EKF part #218.5.024.29), in order to withstand shock and vibration. The latching part may be supplied loosely (not assembled on the PC2-LIMBO, depending on your order), and hence should be snapped onto the CFast™ socket first, before being used. When the
PC2-LIMBO is combined with a low profile mezzanine module such as the C42-SATA, the latching retainer will be replaced by a mounting bar (EKF part #710.9.CFA.B).
There is some ambiguity about the top and bottom side of a CFast™ module - be sure to insert the card properly into the socket. For several CFast™ SSD card brands this would require the module to be inserted with its label facing downwards (to the PCB). However, leading suppliers (e.g. Swissbit) attach the label vice versa on their cards, which requires that such CFast™ modules have to be inserted with their label on top. Anyway, the finger grip, which is recessed into the cards end, should be up. Forced wrong insertion may cause permanent damage to the CFast™ card and the CFast™ host connector.

If the CFast™ host connector is not in use in an application, please remove the latching retainer assembly carefully from the socket (strut the snap-in clips on both sides). As an alternate, use an adhesive tape to fix the CFast™ retaining lever in its normal (locking) position. Otherwise, under worst conditions, the latching spring could cause a short circuit situation when unintentionally moving
(forced by shock or vibration) and touching a PCB in the neighboured board slot of the system rack.
From PCB Rev. 4 off, the CFast ™ card is secured by a small retainer block (screw locked), as can be seen below.

Known issue: Most CFast™ Cards (e.g. Delkin, Swissbit and other brands) work as expected. However,
EKF had also cards under test which showed up strange behaviour. EKF therefore strongly recommends to validate thoroughly a chosen CFast™ card before ordering. If in doubt, please contact [email protected].

PCI Express® Expansion Header J-PCIE
J-PCIE is a high speed connector, which is used widely for EKF side cards with PCI Expess® based I/O controllers. The PC2-LIMBO provides one PE link/lane (1x1) on this connector. Despite most EKF mezzanine side boards are wired as 1x4, they can be operated also from a single PE lane due to autonegotiation, but there may exist also side cards which are not fully compatible with the PC2-LIMBO.
The PCIe lane is derived from a PE packet switch, which is provided on the CompactPCI® PlusIO versions of the PC2-LIMBO. For the CompactPCI® Classic versions of the PC2-LIMBO however, the
PE packet switch is not populated, and the PCIe lane available on J-PCIE is derived directly from the
Topcliff PCH.

Pin Headers & Debug
Front Panel Handle Microswitch Header P-FPH
The jumper P-FPH is used for attachment of an external SPDT switch. By default, P-FPH is connected across a short cable harness to a microswitch, which is integrated into the PC2-LIMBO front panel handle (ejector lever). The switch performs a power button event (e.g. system shutdown) by shortcircuiting the pins 1 and 3 of P-FPH when activated (hold unlock button of front panel handle depressed momentarily).

Processor Debug Header XDP1
The PC2-LIMBO may be equipped with a 26-position processor debug header for hard- and software debugging (specified by Intel® as XDP-SFF-26 Pin Platform Connection). The connector is suitable for installation of a flat flex cable (FFC), in order to attach an JTAG debugger (emulator) such as the
Arium ECM-XDP3. An adapter (ITP-XDP-SFF-26) is required in addition to convert the 26-pin
XDP-SFF-26 Pin connector to the standard 60-pin XDP.
The header XDP1 would be mounted on the PCB bottom side, but is not stuffed by default.

Backplane Connectors
Two hard metric backplane connectors are specified as J1/P1 and J2/P2 by the PICMG® CompactPCI
2.0 and 2.30 (PlusIO). J1 conveys the 32-bit PCI parallel bus, and J2 provides primarily the Rear I/O signals defined by the PlusIO specification.

J2 is a high speed UHM connector, suitable for Gigabit Serial I/O as defined by the PICMG® 2.30
CompactPCI® PlusIO Specification. This specification defines the I/O assignment of the J2/P2 32-bit
CompactPCI® System Slot connector in order to extend the parallel PCI bus with high-speed serial busses. CompactPCI® PlusIO defines the support of PCI, PCI Express, Ethernet, SATA/SAS and USB concurrently. In addition to the parallel PCI bus architecture this I/O specification allows the use of the
CompactPCI® system slot to provide a simple star architecture based on the specified serial bus standards. The PlusIO definition is fully backward compatible to 32-bit CompactPCI® and will interoperate with existing 32-bit systems. This standard allows the implementation of hybrid backplanes: CompactPCI® with CompactPCI® Express and/or CompactPCI® Serial. A 32-bit
CompactPCI® PlusIO System can be used as a system slot for CompactPCI® Serial or CompactPCI®
Express as well.

CompactPCI® Backplane Connector J2 (PlusIO)
The PC2-LIMBO can provide up to 2 x GbE, 4 x PCIe, 4 x SATA and 4 x USB for rear I/O across J2. The
Gigabit Ethernet rear I/O ports are shared with the front panel jacks (setup redirection via BIOS). The
PE lanes are derived from an on-board PE switch (4 links by 1 lane each). With respect to SATA, the channels 3/4 are available either via J2 (stuffing option on request only), or through the mezzanine connector J-HSE (default). SATA 1/2 and SATA 3/4 each have their own dual-port SATA controller
(software RAID capable). The rear I/O USB ports are generated from an on-board 1:4 USB hub.
On CompactPCI® Classic versions of the PC2-LIMBO all components wired for RIO have been removed, and the UHM J2 connector will be replaced by a normal HM connector.Please note, that open PCB copper traces to J2 are still existent, which may downgrade the P2 backplane signal quality
(stubs).
