AT8901 4.4.5 Software Description LEDs For LED positions on the front plane refer to Chapter 3, section 3.10., Display Elements. 4.4.5.1 Hot Swap LED (Blue LED) The AT8901 Hub Board supports a blue Hot Swap LED mounted on the front panel. This LED indicates when it is safe to remove the Hub from the chassis. The on-board IPMC drives this LED to indicate the hot swap state.
AT8901 4.4.5.3 Software Description Health LED (ATCA LED2) Green LED Table 4-6: Health LED state LED state Description ON None of the health sensors is asserted Blinking At least one health sensor is asserted 4.4.5.4 Customer Definable LED (ATCA LED 3) This is an amber LED which can be used by a customer application. This LED can be controlled by PICMG 3.0 defined LED commands. 4.4.6 Hot Swap Process The AT8901 Hub Board has the ability to be hot-swapped in and out of a chassis.
AT8901 4.5 Software Description Firmware Administration A running AT8901 system requires – after the bootloader has passed control to the kernel – the kernel itself, the root file system (initrd), the FASTPATH switching application and a configuration file for base and fabric switch. These software components, together with the IPMC image, make up the AT8901 firmware. The flash holding the software is divided into twelve partitions.
AT8901 Software Description The firmware update procedure is designed to provide a failsafe capability to update IPMC, kernel, initrd, application and configuration settings separately. Each combination of these components can be used as a startup configuration, though they must be compatible to each other. Please always follow Kontron documentation for all your upgrades. Software versions provided with an official release are known to work together.

AT8901 Software Description • One Time Boot capability: After having updated the inactive kernel and root file system, the new system has to be started by rebooting the board. In the case that the update has installed an inoperable system which would cause the board to hang when booting, the next board reset must restart the previous known good version of kernel and root file system. This is achieved by programming the bootloader environment appropriately.
AT8901 Software Description This downloads the specified kernel package file via TFTP and writes the kernel image into the kernel partition of the specified slot (B). The MD5 checksum of the kernel image is checked before writing it into flash. The same procedure can be done with initrd and application packages. It is important not to overwrite the slots containing the currently active software, otherwise the One Time Boot mechanism does not make sense.
AT8901 4.5.3 Software Description Updating IPMI Updating the IPMI firmware is different from updating the other software parts as updating is done directly when invoking the download command. In the case that the update procedure fails or the update image is corrupted, the IPMC will be able to restart all the same by means of its rollback functionality. The IPMI software package file is stored in the result/ppc405/firmware path of the release directory tree.
