IBM SG24-4817-00 manual Control Point Levels, Fpga Code, Control Point Available Highlights

This soft copy for use by IBM employees only.

This code is also on the control point and is executed once the boot code has finished. There are two copies of the code stored in the flash memory. One of these copies is identified as current and is loaded into RAM during the initialization process. This code is executed from RAM. The second copy of the operational code allows new operational code to be loaded into the control point while the control point is running, and then swapped (which resets the ATM subsystem) when it is less disruptive to network operations.

•FPGA Code

This code configures the various internal chips on the IBM 8285 base unit so that they perform their desired ATM functions. There are two copies of the FPGA code stored in flash memory. One of these copies is identified as current code. The current code is loaded into the internal chips of the appropriate components during the initialization process. The second copy of the FPGA code allows new FPGA code to be loaded while the IBM 8285 is operational, and then swapped (which resets the ATM subsystem) when it is less disruptive to network operations.

The following sections describe the code levels that are currently shipped, are announced, or are available in the future.

3.3.1 Control Point Levels

These control point microcode levels (except the obsolete ones) are available on the Internet and can be downloaded via the Web or by FTP. And the code can be downloaded into the IBM 8285 either out-of-band via a SLIP-connected workstation, or inband via an FTP file transfer. For more information about how to get and download the code, refer to 6.4, ªMicrocode/Picocode Considerationsº on page 110.
