Firmware Upgrade Recovery
There are three conditions that call for firmware upgrade recovery:

are unable to operate it.
When a firmware upgrade procedure is interrupted.
When a firmware upgrade procedure fails.
To perform a firmware upgrade recovery, do the following:
1. Power off the CL6700.
2. Connect the Firmware Upgrade Cable to its Firmware Upgrade Port.
3. Slide the Firmware Upgrade Recovery Switch to the Recover position.
4. Power the CL6700 back on and repeat the upgrade procedure.
5. After the CL6700 has been successfully upgraded, power it off, and slide
the Firmware Upgrade Recovery Switch back to the Normal position.
6. Power the CL6700 back on.
Exiting Firmware Upgrade Mode
To exit the Firmware Upgrade Mode, do the following:
1. Slide the Firmware Upgrade Recovery Switch (see page 6) to the Normal
position.
2. Power off and restart the CL6700 according to the instructions given in the
