AOS Release 6.4.6.R01 Release Notes November 2013
Auto-FPGA Upgrade to AOS 6.4.6.R01
Upgrading an OS6850E to 6.4.6.R01 consists of the following steps. The steps must be performed in order.
Observe the following prerequisites before performing the steps as described below:
• This procedure assumes an FPGA/CPLD upgrade is required. If an FPGA/CPLD upgrade is not
required refer to Appendix A for the alternate upgrade procedure.
• An OmniSwitch 6850E-U24X with CPLD version 8 will require a hard reboot (the switch must be
physically powered down and back up) for any CPLD upgrade to take affect.
NOTE: That an OmniSwitch 6850E-U24X with CPLD version 7 or version 8 does not require a
CPLD upgrade when upgrading to 6.4.6.R01.
• CPLD must be upgraded to version 17 for OmniSwitch 6850E with OS-BPS models.
• For OS6850E-C24/P24/C48/P48 models without OS-BPS models, CPLD upgrade to version 17 is
not mandatory.
• Refer to the Version Requirements table to determine the proper code versions.
• Download the appropriate AOS images, Uboot/Miniboot, FPGA files from the Service & Support
website and manualy create the AlcatelDebug.cfg file .
Summary of Upgrade Steps
1. Manually create the AlcatelDebug.cfg file
2. Upgrade the Uboot/Miniboot and AOS images (Reboot required)
3. The OmniSwith automatically upgrades the FPGA/CPLD.
4. Verify the upgrade and remove the upgrade uboot/miniboot and CPLD files from the switch.
