IBM 6500-V05 Maintenance Manual - Page 238

Loading Flash Memory Flash memory is contained in a SIMM (single in-line memory modules) located on the controller board. Printer control languages (the "emulations") and printer operating system software are loaded into flash memory at the factory, but you will install this software in the following situations: The customer needs to upgrade printer software. The customer needs different emulation software. You have replaced the controller board. You have replaced the flash memory SIMM. You can load software through the printer's parallel port or, optionally, through ethernet port if the printer has the ethernet Network Interface Card (NIC) installed. NOTE: To load software through the ethernet port (page 248) you must know the IP Address of the printer and the flash memory must be operational and contain basic printer code (it cannot be a blank replacement SIMM). The recommended procedure is to load through the parallel port. Emulation and operating system software are stored as a single compressed file. The file is "executable;" you will expand it and copy it into printer flash memory with a single command. DANGER Do not connect or disconnect any communications port, teleport, attachment connector, or power cord during an electrical storm. Power off the printer and disconnect the power cord before connecting or disconnecting a communication port, teleport, or attachment cable connector. 238
