Reloading the Bridge Image
Reloading the Bridge Image
If your bridge has a firmware failure, you must reload the complete bridge image file using the Web
browser interface or by pressing and holding the MODE button for around 30 seconds. You can use the
browser interface if the bridge firmware is still fully operational and you want to upgrade the firmware
image. However, you can use the MODE button when the bridge has a corrupt firmware image.
Using the MODE button
You can use the MODE button on the bridge to reload the bridge image file from an active Trivial File
Transfer Protocol (TFTP) server on your network or on a PC connected to the bridge Ethernet port.
Note If your bridge experiences a firmware failure or a corrupt firmware image, indicated by three red LED
indicators, you must reload the image from a connected TFTP server.
Note This process resets all configuration settings to factory defaults, including passwords, WEP keys, the
bridge IP address, and SSIDs.
Follow the steps below to reload the bridge image file:
Step 1 The PC you intend to use must be configured with a static IP address in the range of 10.0.0.2 to 10.0.0.30.
Step 2 Make sure the PC contains the bridge image file (TBD) in the TFTP server folder and the TFTP server
is activated. For additional information, refer to the “Obtaining the Bridge Image File” and “Obtaining
the TFTP Server Software” sections.
Step 3 Connect the PC to the bridge using a Category 5 (CAT5) Ethernet cable.
Step 4 Disconnect the power jack from the power injector.
Step 5 Press and hold the MODE button while you reconnect power to the power injector.
Step 6 Hold the MODE button until the status LED turns red (approximately 20 to 30 seconds), and release the
MODE button.
Step 7 Wait until the bridge reboots as indicated by all LEDs turning green followed by the Status LED
blinking green.
Step 8 After the bridge reboots, you must reconfigure the bridge by using the Web interface, the Telnet
interface, or IOS commands.
Note The bridge is configured with the factory default values including the IP address (set to receive an IP
address using DHCP). To obtain the bridge’s new IP address, refer to the “Using the IP Setup Utility”
section on page 4-9.
