Perform the steps below from a properly working thin
client.
Note: A blank CompactFlash card is required to perform
this procedure.
1. Perform Steps 1 to 4 in "Removing the logic unit" on
page 33.
2. If a CompactFlash card is already installed, remove it
by carefully pulling out of the flash card slot. If a
CompactFlash card is not installed, go to step 3.
3. Carefully insert a blank CompactFlash card into the
flash card slot. This CompactFlash card is your
recovery CompactFlash card.
For more information on CompactFlash cards, see
"Appendix C. CompactFlash card" on page 35.

configuration 2 .
5. Reconnect the power cable to the logic unit.

LED to flash green.
If the system LED flashes amber, the image was not
created. Repeat the procedure with another
CompactFlash card.
7. Power off the thin client.
8. Remove the recovery CompactFlash card.
9. Move the jumpers back into the default configuration
1 .
