Make sure that you download the specific *.BIN file
for your device type. Uploading incorrect firmware for
the device type will cause the firmware overwrite to
fail, and may damage the unit.
The following procedure describes how to overwrite the existing firmware

currently active.
To overwrite the existing firmware on the Cisco device, do the
following steps:

network.
Disconnect all Ethernet cables from the Cisco device.2.
3. With the Cisco device disconnected from the wireless
network, power ON the device.
CAUTION
Do not restart or power OFF the device while
firmware overwriting is in progress.
Restarting or powering OFF the unit before
overwriting is complete will permanently damage the
unit.
4. Connect the computer containing the firmware image file directly
to the Cisco unit, using an Ethernet cable. For detailed
information on direct connection, refer to “Accessing the Cisco
FM4200 Fiber for device configuration” (page 57).
5. As a precaution, save the unit's existing device configuration file
to the computer. For detailed information on how to save the
existing configuration file, refer to “Saving and restoring the unit
