For more information regarding the PCD7.R500, please refer to the PCD3 hardware manual.Even if the PCD7.R550M04 is electrically hot un-pluggable, the removal of a device shall be carefully done. This device has no LED providing information if the device is currently accessed or not.Two cases shall be carefully studied when a flash device is removed:■ Some write operations are currently going on. These operations can be per-formed either by the user program or by FTP. Before removing the device, put the Saia PCD® in STOP if the user program is writing on a flash device and make sure that no FTP connection is currently on-going.■ The compression algorithm is currently going on. This operation is either trig- gered by the user program (directly triggered or indirectly through erasing of files) or indirectly by FTP after erasing files. These actions are difficult to detect by external users.
