Safety Instructions

Before You Begin

Before handling the board, read the instructions and safety guidelines on the following pages to prevent
damage to the product and to ensure your own personal safety. Refer to the "Advisories" section in the
Preface for advisory conventions used in this user's guide, including the distinction between Warnings,
Cautions, Important Notes, and Notes.

• Always use caution when handling/operating the computer. Only qualified, experienced,
authorized electronics service personnel should access the interior of the computer. The power
supplies produce high voltages and energy hazards, which can cause bodily harm.

• Use extreme caution when installing or removing components. Refer to the installation
instructions in this user's guide for precautions and procedures. If you have any questions, please
contact Kontron Technical Support

WARNING

High voltages are present inside the chassis when the unit's power cord is plugged
into an electrical outlet. Turn off system power, turn off the power supply, and then
disconnect the power cord from its source before removing the chassis cover. Turning
off the system power switch does not remove power to components.

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 metalic 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.

1.6 Interfacing with the Environment

1.6.1 RTM (rear transition module)

The RTM is a single slot (6HP) AdvancedTCA Rear Transition Module. This module provides additional
connectivity for AT8940 CPU front blade.

1.6.1.1 Standard Compliance

• PICMG® 3.0 R3.0 Advance TCA™ base specification

• PICMG® 3.1 R2.0 Advance TCA™ Ethernet specification

1.6.1.2 Hot Swap

The RTM 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 RTM is
removed. This procedure meets the AdvancedTCA AMC behavior.

1.6.1.2.1 Inserting the RTM 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
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 RTM 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. (RTM removed from the slot)
