File written to the file system by the PCD can’t be accessed with HTTP protocol

FAQ #101686

You try to access a File on the Web-Server of the PCD with the HTTP protocol e.g. with an Internet Browser. The Web-Server responds with the Error message File not found. (HTTP 404 Not found)


The Web-Server can't find the file although it is visible with FTP access.

This happens because the file system has just been formatted with the Memory management FBox before.

After formatting the file system with the Memory Management FBox it is necessary to switch off / on the PCD (remove 24V). For PCD3.R600 flash memory modules there is also another solution the SD-card can be removed and reinserted. After this operation the file can again be accessed with HTTP protocol.

This inconvenience will remain on FW versions <= 1.16.xx but it will be corrected for future firmware versions. It won't be necessary anymore to switch off / on the PCD.
