AII How to recover Compex WPE54AG from failed firmware
Before starting, check the status of the DIAG LED against Table 1 above to verify
whether firmware failure has occurred.
1. Power Compex WPE54AG off and disconnect it from the network.
2. Use a MDI cable (cross-connect for Compex WPE54AG) to connect the LAN port
of Compex WPE54AG to the LAN port of your computer.
3. Power Compex WPE54AG on, and then start up your computer. The computer will
obtain an IP address of 192.168.168.100 from Compex WPE54AG.
4. Insert Compex WPE54AG Product CD into the CD drive of your computer.
5. From the computer, click Start, then Run and type in the following command:
X:TFTP -i 192.168.168.1 PUT X:image_name.IMG, where X refers to your CD
drive and image_name.IMG to the firmware filename found in the Recovery
folder of the Product CD.
6. If you have downloaded a newer firmware and have saved it in your local hard disk
as for example, C:\Compex WPE54AG\wp54gxxxx.IMG, then replace
X:\image_name.IMG with this new path and firmware name.
7. The recovery process will now take place. You can check the DIAG LED against
Table 1 to monitor the progress of the recovery process.
