Downgrading Using the DFW Command
1. If problems are encountered during the firmware update procedure, it may be necessary to
use the management processor dfw command. The dfw command can be used to copy a
PDHC or a System firmware image from one cell to another. The steps for upgrading using
the dfw command are the same as listed in “Upgrading Using the DFW Command” (page 129)
with two additional steps:
1. OSP the PDHC FPGA image to the new cell.
2. Use DFW to copy the PDHC image to the new cell image A.
3. Use DFW to copy the PDHC image to the new cell image B.
4. AC power cycle the Cell.
5. Use DFW to copy the System Firmware image to the new cell image A.
6. Use DFW to copy the System Firmware image to the new cell image B.
2. Perform step 1 from Step 1 and step 2 from Step 2.
Do not reset the Cell until step 4 on Step 4 has been completed.
3. Example (To downgrade the PDHC image A firmware)
