Page 18: 2/ Cp6940 Installation
Safety Requirements The following safety precautions must be observed when installing or operating the CP6940. Kontron assumes no responsibility for any damage resulting from failure to comply with these requirements. Due care should be exercised when handling the board due to the fact that the heat sink can get very hot. -
Page 19: Cp6940 Initial Installation Procedures
CP6940 User Guide CP6940 Initial Installation Procedures The following procedures are applicable only for the initial installation of the CP6940 in a system. Procedures for stan- dard removal and hot swap operations are found in their respective chapters. To perform an initial installation of the CP6940 in a system proceed as follows: Ensure that the safety requirements indicated in chapter Safety Requirements are observed. -
Page 20: Standard Removal Procedures
Ensure that the safety requirements indicated in chapter Safety Requirements are observed. Care must be taken when applying the procedures below to ensure that neither the CP6940 nor other system boards are physically damaged by the application of these procedures. -

Gigabit Ethernet Serviceport The Gigabit Ethernet serviceport on the CP6940 front plate has no IP address set by default, it is necessary to assign an IP address statically or enable dhcp on the serviceport. Because the required configuration steps are done in the CLI, an ini- tial access using the serial port is required. -
Page 22: In-Band Cli Access
In-Band CLI Access The GbE switch network port (in-band management access) on the CP6940 has no IP address set by default, it is neces- sary to assign an IP address either statically or by using DHCP to the network port. Because the required configuration steps are done in the CLI, an initial access using the serial port is required. - Page 23 To access the CLI via Gigabit Ethernet networkport, open a telnet connection to the configured IP address, port 23. It might make sense to separate the management network from the data path by setting appropriate VLANs For additional information on the system configuration, refer to the CP6940 CLI Reference Manual. www.kontron.com...

SNMP can also be used for updating System Software, IPMI FW and PLD. Bootloader On the CP6940 Ethernet Switch, the bootloader 'u-boot' (universal bootloader) is used. The bootloader initializ-es the main components of the system like Unit Computer, DDR3 RAM, serial lines etc. for operation and per-forms a power on self test (POST). -

CP6940 User Guide 4.3.2 Bootloader Shell Options The boot process can be interrupted by entering the bootstopkey phrase “stop”. This will open a bootloader shell session. Entering "?" provides a list of possible built-in commands, "printenv" provides a list of current environment settings. The bootloader shell allows to customize boot options and system startup by changing some of its environment variables. - Page 52 CP6940 User Guide Meddling with the bootloader environment variables can affect significantly the startup sequence of the system and may cause the system to be un-bootable. Bootloader environment variables can be modified and stored using the 'env set' and 'env save' bootloader CLI com- mands.

Additional, there are two temperature sensors for the inlet/outlet air temperature available. As long as the temperature values stay below their upper critical threshold, all components on the CP6940 are consid- ered to be operated within their specified temperature range. -
Page 71: Table 33: Thermal Requirements
CP6940 User Guide When developing applications using the CP6940, the system integrator must be aware of the overall system thermal requirements. A system chassis must be provided which satisfy these requirements.

Page 72: 6/ Power Considerations
CP6940 system environment. The CP6940 has been designed for optimal power input and distribution. Still it is necessary to observe certain criteria essential for application stability and reliability. The board is supplied by 3.3V and 5.0V from the backplane. All supply voltages from the backplane are enabled with a predefined ramp-up time. - Page 73 CP6940 User Guide About Kontron Kontron is a global leader in Embedded Computing Technology (ECT).
