Appendix C Firmware Upgrade and Downgrade Procedures
Standard Upgrade and Downgrade Procedures
Step 6 Enter the version command. This command displays the version of the boot code currently stored in
Flash memory. This step downloads new firmware into the ASC.
Step 7 Enter the tftp put <ASC_FW_file> AXIS_ASC_ACTIVE.FW command.
Step 8 Check the file size of the downloaded firmware. Use this step to check that the firmware was
downloaded successfully to the ASC disk.
Step 9 Enter the dspfwrevs command to verify the correct firmware revision.
Step 10 For all SMs enter the flashStartAddr and flashEndAddr commands to start the Flash memory file at
Oxbfc00000 and end it at 0xbfc40000
shelf.1.<slot>.<type><a|s>flashStartAddr = 0xbfc00000
shelf.1.<slot>.<type>.<a|s>flashEndAddr = 0xbfc40000
Step 11 Enter the tftp put <SM_BT_file> AXIS_SM_1_$slot.FW command.
Step 12 Enter the chkflash command. This command calculates and compares the Flash checksum to verify
whether the boot code is correct.
Step 13 Enter the version command. This command displays the version of the boot code currently stored in
Flash memory. This step downloads new firmware into the ASC.
Step 14 For all SMs enter the flashStartAddr and flashEndAddr commands to start the Flash memory file at
0xbfc40000 and end it at 0xbfd00000
shelf.1.<slot>.<type><a|s>flashStartAddr = 0xbfc40000
shelf.1.<slot>.<type>.<a|s>flashEndAddr = 0xbfd00000
Step 15 Enter the tftp put <SM_FW_file> AXIS_SM_1_$slot.FW command.
Step 16 Enter the chkflash command. This command calculates and compares the Flash checksum to verify
whether the boot code is correct.
Step 17 Enter the resetsys or clrallcnf command. These commands reset all cards on the shelf.
Step 18 Set the BRAM revision.
Step 19 Enter the dspadrxlat command to ensure that the number of connections is correct.
Step 20 For all primary and stand-alone SMs, enter the dsptotals commands.
Use this step to examine the number of lines, ports, and channels after the upgrade or downgrade. The
values can be compared to those before the download and, therefore, it can be established that the
configuration has remained the same. Restore the ASC and SM configurations if necessary.
Procedure 3—Standard Upgrade, 2-Core Card Set
Procedure 3 is used for 1.2.x to 2.y, 2.2.x to 3.x, and 3.3.x to 3.y.
Step 1 Save the current ASC configuration. Perform this step for the ASC prior to upgrading the firmware.
First reset the card, then use TFTP get to save the card’s current configuration in the workstation.
tftp shelf
tftp> bin
tftp> get AXIS_ASC_ACTIVE.BR
Step 2 Save the current service module (SM) configuration for each primary and stand-alone SM. Perform this
step for the SM prior to upgrading the firmware.
