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 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.

Safety instructions
v RTM8020 User's Guide
When Working Inside a Computer
Before taking covers off a computer, perform the following steps:
• Turn off the computer and any peripherals.
• Disconnect the computer and peripherals from power sources or subsystems to prevent electric
shock or system board damage. This does not apply to when hot-swapping parts.
• Follow the guidelines provided in "Preventing Electrostatic Discharge" on the following page.
• Disconnect telephone or telecommunications lines from the computer.
In addition, take note of these safety guidelines when appropriate:
• To help avoid possible damage to system boards, wait five seconds after turning off the computer
before removing a component, removing a system board, or disconnecting a peripheral device from
the computer.
• When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the cable
itself. Some cables have a connector with locking tabs. If you are disconnecting this type of cable,
press in on the locking tabs before disconnecting the cable. As you pull connectors apart, keep
them evenly aligned to avoid bending any connector pins. Also, before connecting a cable, make
sure both connectors are correctly oriented and aligned.
CAUTION
Do not attempt to service the system yourself, except as explained in this user’s
guide. Follow installation and troubleshooting instructions closely.

Safety instructions
vi RTM8020 User's Guide
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 procedures, 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.

1.6 Interfacing with the Environment
1.6.1 RTM (rear transition module)
The RTM8020 is a single slot (6HP) ATCA Rear Transition Module. This module provides additional
connectivity for AT8020 CPU front blade.
1.6.1.1 Standard Compliance
• PICMG3.0 R2.0 ECN002 - Advanced Telecommunication Computing Architecture
• SAS1R10 - Serial Attached SCSI - 1.1 Revision 10. (SAS-1.1)
• SFF-8470 (T10 Technical Committee and SCSI Trade Association)
1.6.1.2 SAS Feature
• Total of two (2) 3Gbit/s SAS ports available on the RTM face plate through one external SAS connector
• Compliant to SAS-1.1 Revision 10 / SFF-8470
• SAS signal integrity guarantee over a four meters cable
1.6.1.3 Serial Port Feature
• One (1) serial port available on the RTM face plate through one (1) RJ-45 connector.
• RS-232 signals level at RTM face plate connector.
• Serial port speed capability is: 9kbits/s to 115kbits/s.
1.6.1.4 Onboard SAS Drive
• Support one (1) 2.5” SAS Drive
• Support dual-port SAS Drive
1.6.1.5 FRU Data EEPROM
• FRU Data EEPROM size is 64Kbit (8K * 8 bit)
1.6.1.6 Hot Swap
The RTM8020 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
RTM8020 is removed. This procedure meets the ATCA AMC behavior.

1.6.1.6.1 Inserting the RTM8020 into the slot
The presence of the RTM is indicated by two signals. The front blade IPMC recognizes the RTM insertion when
the two signals are low (lower ejector handle closed). After recognizing the RTM, the MMC turns the blue LED
ON and enables the 3.3V_SUS to the RTM. Once the I2C link is working, the MMC accesses the serial EEPROM
to retrieve FRU data. After knowing the type of RTM inserted, the MMC negotiates with System Manager in
order to activate the +12V payload power. After RTM local voltages have been ramped up, the MMC enables
the RTM Link.
After this the IPMC informs the CPU SW there is a functional RTM blade present.
1.6.1.6.2 Removing the RTM8020 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 MMC then negotiates the removal with the System
manager and if it is granted, it proceeds with the removal process.
The MMC first notifies the CPU SW of coming hot removal. After the CPU SW has disabled SAS links, it notifies
the MMC that the RTM blade can be removed. The MMC then activates reset to the RTM blade (via the
Expander), disables the RTM Link and turns OFF the payload +12V power. When it is safe to remove the RTM
blade from the slot, the MMC turns the Blue / Hot Swap LED ON. Front Blade IPMC turns OFF the management
power only when their is no RTM detected. (RTM8020 removed from the slot)

2.3 SAS Link
The RTM8020 has two (2) 3Gbits/s SAS links available on the face plate through one (1) SAS connector. These
links are coming from the front blade through the zone 3 connector. A SAS signal conditioner is needed to
guarantee SAS signal integrity over the cable between two RTM blades. The maximum SAS cable length
between two RTM blades is 4m.
2.4 SAS Hard Drive Option
Kontron offers the option of adding a SAS hard drive on the RTM8020. This hard drive is located on the
component side of the PCB, in the lower part of the RTM8020.
2.5 Serial Port
The RTM8020 has one serial port available on the RTM face plate. Serial port signals are coming from the
front blade through zone 3 connector. Serial Port on this RTM is COM2 from the AT8020. A RS232 buffer is
used on the RTM to convert signal TTL level from zone 3 to RS232 signal level at the face plate connector.
Serial port works from 9kbits/s to 115kbits/s.
