Appendix C Firmware Upgrade and Downgrade Procedures

Standard Upgrade and Downgrade Procedures

Procedure 9—Standard Upgrade, 1-Core Card Set

Procedure 9 is used for 4.x to 4.y, 4x to 5.x, and 5.x to 5.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.

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_SM_1_<slot>.PRI.<service password>

Step 3 Enter the dspadrcxat command. Note the value of the ConnNumOfValidEntries parameter.

This value indicates the number of connections. This command is run again at the end of the procedure to ensure that the number of connections did not changed.

Step 4 For all stand-alone and primary SMs

a.Enter the dsptotals command.

The configuration of the shelf should not be changed during the downgrade process. Use this step to examine the number of lines, ports, and channels before the upgrade or downgrade. A similar step can be made to examine the same configuration parameters after the upgrade or downgrade and, therefore, it can be established that the configuration has remained the same.

b.Enter the tftp put <ASC_BT_file> AXIS_ASC_BACKUP.FW command. This step downloads the new boot code into the ASC.

c.Enter the chkflash command. This command calculates and compares the Flash checksum to verify whether the boot code is correct.

d.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.

e.Enter the tftp put <ASC_FW_file> AXIS_ASC_ACTIVE.FW command.

f.Enter the file size of the downloaded firmware. This step is used to check that the firmware Enter the dspfwrevs command to verify the correct firmware revision.

Step 5 For all SMs

a.Enter the tftp put <SM_BT_file> AXIS_SM_1_$slot.BOOT command.

b.Enter the chkflash command. This command calculates and compares the Flash checksum to verify whether the boot code is correct.

c.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.

d.Enter the tftp put <SM_FW_file> AXIS_SM_1_$slot/0.FW command.

e.Check the file size of the downloaded firmware. This step is used to check that the firmware was downloaded successfully to the ASC disk.

f.Enter the dspfwrevs command. This command displays the current firmware revisions.
