Preventing Electrostatic Discharge
Static electricity can harm system boards. Perform service at an ESD workstation and follow proper ESD
procedure to reduce the risk of damage to components. Kontron strongly encourages you to follow proper
ESD procedure, which can include wrist straps and smocks, when servicing equipment.
Take the following steps to prevent damage from electrostatic discharge (ESD):
•When unpacking a static-sensitive component from its shipping carton, do not remove the
component's antistatic packing material until you are ready to install the component in a
computer. Just before unwrapping the antistatic packaging, be sure you are at an ESD workstation
or grounded. This will discharge any static electricity that may have built up in your body.
•When transporting a sensitive component, first place it in an antistatic container or packaging.
•Handle all sensitive components at an ESD workstation. If possible, use antistatic floor pads and
workbench pads.
•Handle components and boards with care. Don't touch the components or contacts on a board. Hold
a board by its edges or by its metal mounting bracket.
•Do not handle or store system boards near strong electrostatic, electromagnetic, magnetic, or
radioactive fields.
•When you want to remove the protective foil (if present), make sure you are properly grounded and
that you touch a metallic part of the board.
CAUTION
Removing the protective foil from the top and bottom cover might create static.
When you remove those protections, make sure you follow the proper ESD procedure.

1.4 Compliance
This product conforms to the following specifications:
• PICMG3.0 R3.0 (Advanced TCA Base Specification)
• PICMG3.1 R1.0 (Ethernet/Fiber Channel over AdvancedTCA)
• PICMG3.1 R2.0 (AdvancedTCA Ethernet specification(Draft))
•HPM.1
•IPMI 2.0
1.5 Hot-Plug Capability
The AT8242 supports Full Hot Swap capability as per PICMG3.0 R3.0 for the board itself. It can be removed
from or installed in the system while it is on (without powering-down the system). Please refer to the
PICMG3.0R3.0 specification for additional details about Hot Swap.
1.6 Interfacing with the Environment
1.6.1 RTM (rear transition module)
The RTM8242 is a single slot (6HP) AdvancedTCA Rear Transition Module. This module provides additional
connectivity for AT8242 CPU front blade.
1.6.1.1 Standard Compliance
• PICMG3.0 R3.0 - Advanced Telecommunication Computing Architecture
1.6.1.2 Hot Swap
The RTM8242 supports hot swapping by using the switch connected to the face plate lower ejector. This
switch indicates the coming hot swap action. The insertion of the RTM to a slot is always done over a non
powered connector. During the extraction procedure, the management power is disabled only when the
RTM8242 is removed. This procedure meets the AdvancedTCA AMC behavior.
1.6.1.2.1 Inserting the RTM8242 into the slot
The presence of the RTM is indicated by one signal. The front blade IPMC recognizes the RTM insertion when
the signal is low. After recognizing the RTM, the IPMC turns the blue LED ON and enables the management
power to the RTM. Once the IPMB-L link is working, the IPMC accesses the MMC to retrieve FRU data. After
5AT8242
Product Description
www.kontron.com
knowing the type of RTM inserted, the IPMC negotiates with the shelf manager in order to activate the +12V
payload power. After RTM local voltages have been ramped up, the RTM’s MMC enables the RTM Link.
After this the front board IPMC informs the shelf manager there is a functional RTM blade present.
1.6.1.2.2 Removing the RTM8242 from the slot
The RTM_EJECT signal goes HIGH by opening the RTM lower ejector handle. This indicates to the front blade
IPMC that a hot swap action is going to take place. The IPMC then negotiates the removal with the System
manager and if it is granted, it proceeds with the removal process.
The IPMC proceeds to the deactivation by disabling ekey governed links, the IPMC then disables the RTM Link
and turns OFF the payload +12V power. When it is safe to remove the RTM blade from the slot, the IPMC turns
the Blue / Hot Swap LED ON. Front Blade IPMC turns OFF the management power only when there is no RTM
detected. (RTM8242 removed from the slot)

2.5 Serial Interfaces
The AT8242 uses serial interfaces to manage the NPU0, NPU1 and the P2010. Since no video interface is
provided on board, the only way to get visual information on the board is the serial console. They are 16C550
high-speed UART compatible and support 16-byte FIFO buffers for transfer rates from 9.6Kbps to 115.2Kbps.
The default Serial port speed for OS shell access is 115.2 kbps.

www.kontron.com
Note:
Standard product uses a RJ-45 8 pins connector. RI (ring indicator) and DCD (data carrier detect)
signals are not available.
The pinout is a custom one, not the same as RS-232D TIA/EIA-561.
2.6 Serial-Over-LAN (SOL)
The AT8242 supports Serial-Over-LAN on both Base Interfaces channels with a default speed of 115.2 kbps.
There is one SOL instance dedicated to Unit Processor (P2010) and one SOL instance dedicated to each NPUs
(Cavium). The communication on the Front Plate serial connection will take priority if a cable is present.
IPMI-Over-LAN allows Serial-Over-LAN (SOL) Payload traffic.
2.7 Web Interface
The AT8242 provides a Web interface. This interface provides the sensor list and their corresponding
readings. It also provides a power control page for the Unit Processor (P2010). This page gives the possibility
to initiate a graceful shutdown, a power down, a power cycle and a payload reset.
Note:
Power up is not supported by the Web interface because the Base Interface is not available without
payload power.
The Web interface also provides a power control page for the NPUs (Cavium). This page gives the possibility to
do a graceful shutdown, power down, power up, power cycle or a reset of each NPU independently (within its
virtual AMC domain).
2.8 FPGA
The FPGA has many functions. One of them is to act as a companion chip to the IPMC. The states of all the
critical signals controlled by the IPMC are memorized in the FPGA and are preserved while the IPMC firmware
is being updated.
The FPGA is a RAM-based chip that is preloaded from a separate flash memory at power-up. Two such flash
memory devices are provided; one that can only be programmed in factory and the other one that can be
updated in the field. The factory flash is selected by inserting jumper JP1 pins 1-2. Field updates require a
power-cycle of the board. The IPMI LED2 will blink amber if the factory flash is being used to signal a fail safe
configuration.
The FPGA update complies to PICMG HPM.1 specification and is remotely updatable via any IPMC channel.
