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

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.

1.4 Hot-Swap Capability

The RTM8940 supports Full Hot Swap capability as per PICMG3.0 R3.0. It can be removed from or installed in
the system while it is on (without powering-down the system). Please refer to the PICMG3.0 R3.0
specification for additional details.

1.5 Interfacing with the Environment

1.5.1 RTM (rear transition module)

The RTM8940 is a single slot (6HP) AdvancedTCA Rear Transition Module. This module provides additional
connectivity for AT8940 Hub front boards.

1.5.1.1 FRU Data EEPROM

• FRU Data EEPROM size is 32Kbit and it includes board identification and serial number information.

1.5.1.2 Hot Swap

As a Hot Swappable Intelligent Managed FRU, the RTM8940 (FRU2) includes a Management Controller, the
AdvancedTCA Hot Swap indicator (Blue LED) and the standard AdvancedTCA handle switch.

1.5.1.2.1 Insertion and Removal of the Managed FRUs

After insertion, the front board detects and activates the management components of the FRU. When the
handle is closed, the power budget and the e-keying negotiations start. Then, the front board's IPMC
activates the payload components of the FRU.

Opening the RTM handle switch on the RTM FRU and will start the deactivation process, which deactivates the
RTM8940.

The operational state of the FRU is reported through the management subsystem FRU Hot Swap sensors. The
BLUE LED is 100% off when a FRU is operational and unsafe for extraction. An always on(100%) indicates
that a FRU can safely be extracted; transitional states are identified through blinking patterns. Additional
details on the standard FRU Hot Swap sensor and the BLUE LED usage can be found in the AdvancedTCA
specifications.

• 2 ETSI T3 E1/T1 BITS input/outputs

• 2 ETSI T4 E1/T1 Upstream/Downstream Chassis Clock Support.

2.6 MMC Boot Block

The MMC runs a firmware from its internal 256KB flash. It is programmed by an additional 8K boot block. It
keeps the last two copies of the MMC firmware in dedicated flash memories. The boot block activates the MMC
image and can rollback a firmware update in the MMC in case of problems.

2.7 Hardware Management Overview

The RTM communicates with the front board using the IPMB-L channel. Kontron Intelligent RTM address on
the IPMB-L is fixed and has a value of 0xA6.

The memory subsystem of the MMC consists of an integrated flash memory to hold the MMC operation code
and integrated RAM for data. The field replacement unit (FRU) inventory information is stored in the
nonvolatile memory on an EEPROM connected via a local I2C interface to the MMC. It is possible to store up to
4 KBytes within the FRU inventory information. Event generation over IPMB-L bus to reach the front board
that forward it to the ShMc ensure that 'post-mortem' logging information is available even if the power of
the RTM is disabled.

The onboard DC voltages and temperature are monitored by the MMC device. The MMC will send an event to
the front board if any of the thresholds are exceeded.

To increase the reliability of the RTM8940 management subsystem, an external watchdog supervisor for the
MMC is implemented. The MMC must strobe the external watchdog at 500 μsec. intervals to ensure continuity
of operation of the board's management subsystem. If the MMC ceases to strobe the watchdog supervisor,
the watchdog resets the MMC. The watchdog timeout expires after one second if strobes are not received. The
external watchdog supervisor is not configurable and must not be confused with the IPMI v1.5 watchdog
timer commands. This external watchdog of the MMC is implemented in a separate chip.

2.7.1 Sensor Data Record (SDR)

Every sensor on the RTM is associated with a Sensor Data Record (SDR). Sensor Data Records contain
information about the sensors identification such as sensor type, sensor name and sensor unit. The SDR also
contains the configuration of a specific sensor such as threshold/hystheresis and event generation
capabilities that specifies sensor behaviour. Some fields of the SDR are configurable through IPMI v1.5
command and are set with built-in initial values. Finally, one field which is the sensor owner must reflect the
module addresses that allows a system management software to identify the owner of the SDR when it is
scanned from the front board IPMC and merged within the IPMC Device SDR repository.

From IPMI prespective, the RTM8940 management controller is set up as a satellite management controller
(SMC). It does support sensor devices, and use the IPMI static sensor population feature of IPMI v1.5 to
merge the hot swaped RTM sensor with the front board sensors population. The usual way the SHMC is

8 RTM8940

www.kontron.com

informed about an RTM insertion is through the RTM Module Hot Swap sensor and a radial presence line on
the RTM connector. All SDRs can be queried using Device SDR commands. Module sensors that have been
implemented are listed below.

2.7.4 MMC Firmware Code

MMC firmware code is organized into boot code and operational code, both of which are stored in a flash
module. Upon an MMC reset, the MMC executes the boot code and performs the following:

1 Self test to verify the status of its hardware and memory.

2 Performs a checksum of the operational code.

3 Set operational state that tells the boot block the firmware operate correctly.

Upon successful verification of the operational code checksum, the firmware will jump to the operational
code.

2.7.5 MMC Firmware Upgrade Procedure

The upgrade procedure is compliant to PICMG HPM.1. MMC Firmware upgrades can be done by using IPMITOOL
from sourceforge
through any IPMI interface without payload impact.

from the front board or remotely on the chassis. It has been designed to be upgradable

www.kontron.com

2.7.6 Boot Block Upgrade Procedure

Type the following to perform MMC firmware upgrade

ipmifwu -fb <file> -P /dev/ttyS1 -M rtm -p <ENTER>

Note:

During boot block firmware upgrade the MMC is held in reset

2.7.6.1 Hot-Swap Process

The RTM8940 has the ability to be hot-swapped in and out of the front board. The onboard MMC manages the
RTM's power-up and power-down transitions. The list below illustrates this process for power down request.

1 Ejector latch is opened. HOT_SWAP_PB# assertion. MMC firmware detects the assertion of this

signal.

2 MMC sends "Module Handle Open" event message to the front board. The corresponding M state of

the front board moves from M4-> M5.

3 The front board moves from M5 -> M6 if the SHMC grants the request. The front board IPMC sends

the FRU control requesting quiesced state to the RTM.

4 The firmware deasserts payload power and sends "Module Quiesced" event message to the front

board where it transitions from M6 to M1 state.

Note:

Depending on your BIOS configuration, a hot-swap process might turn off the front board. Please
refer to the BIOS section “Managed FRU Deactivation Policies” of the AT8940.

2.7.6.2 Hot-Swap LED

The RTM8940 and RTMDISK supports a blue Hot Swap LED mounted on the front panel. This LED indicates
when it is safe to remove the RTM from the front board. The on-board MMC drives this LED to indicate the hot­swap state. The following states are possible:

Table 2-6:Hot-Swap LED Description

LED state Description

OFF M4 state; normal state when board is in operation.

ON M1 state; ready for hot swap.

Short blink M5 state; deactivation request

Long blink M2 state; activation request.

When the RTM latch is disengaged from the faceplate, the hot swap switch embedded in the PCB will assert a
"HOT_SWAP_PB#" signal to the MMC, and the MMC will send “Module Handle Open” event message to the
front board which moves from the M4 state to the M5 state. Once in the M5 state, the front board will ask the
SHMC (or Shelf Manager) for permission to move the RTM to the M6 state. Then the IPMC of the front board,
through IPMB-L, will set the RTM Hot Swap LED to indicate this state with a short blink. Once permission is
received from the SHMC or higher-level software, the front board will move to the M6 state.

13 RTM8940

www.kontron.com

The SHMC or higher level software can reject the request to move to the M6 state. If this occurs, the RTM will
return the Hot Swap LED to a solid off condition, indicating that the RTM has returned to M4 state.

If the RTM reaches the M6 state through an extraction request from the RTM handle latch, the MMC
communicates to the front board that the module must discontinue operation in preparation for removal. The
Hot Swap LED continues to flash during this preparation time, just like it does at the M5 state. When main
RTM payload power is successfully removed from the RTM slot, the Hot Swap LED remains lit, indicating it is
safe to remove the RTM from the chassis or the hard disk from the RTM.

Refer to the AT8940 manual for information on "Managed FRU Deactivation Policies" affecting the FRU
deactivation process.

2.8 Face Plate Indicators

All LEDs can be overriden with standard PICMG LED APIs

2.8.1 Hot Swap LED (LED0)

The Blue / Hot Swap LED indicates the hot swap status of the RTM. The LED is ON when it is safe to remove the
RTM from the slot. During normal operation, this LED is OFF.

2.8.2 Out Of Service (LED1)

The AdvancedTCA LED1 is red or amber and indicates an Out-of-Service (OOS) condition. During normal
operation, the OOS LED is OFF. This LED is ON during firmware upgrade and is user configurable if needed by a
customer application.

2.8.3 Healthy LED (LED2)

The AdvancedTCA LED2 is green or amber and indicates a healthy condition. The healthy LED indicates if the
blade is powered up and all voltages and temperatures are within specifications. During normal operation,
this LED is ON (green). This LED is also ON (amber) when one of the RTM8940 voltage or temperature sensor
pass a threshold.

2.8.4 QSFP+, SFP+ and SFP LED

The Green LEDs indicate the link status of the connection. The LED is ON when there is a link otherwise, it’s
OFF.

3.1 RTM Hot Swap and Installation

Because of the high-density pinout of the hard-metric connector, some precautions must be taken when
connecting or disconnecting a RTM to/from an AT8940:

1 Rail guides must be installed on the enclosure to slide the RTM to the AT8940.

2 Do not force theRTM if there is mechanical resistance while inserting it.

3 Screw the faceplate to the enclosure to firmly attach the RTM to its enclosure.

4 Use extractor handles to disconnect and extract the RTM from its enclosure.

WARNING

Always use a grounding wrist wrap before installing or removing the board from a
chassis.

3.1.1 Installing the RTM in the chassis

To install the RTM:

1 Remove the filler panel from the slot.

2 Ensure the RTM is configured properly.

3 Carefully align the PCB edges at the bottom and top card guide.

4 Insert the RTM in the system until it makes contact with the CPU board.

5 Using both ejector handles, engage the RTM in the front board connectors until both ejectors are

locked.

6 Fasten screws at the top and bottom of the faceplate.

3.1.2 Removing the RTM from the chassis

To remove the RTM:

1 Unscrew the top and the bottom screw of the faceplate.

2 Unlock the lower handle latch.

3 Wait until the blue LED is fully ON, this mean that the hot swap sequence is ready for RTM removal.
