8 Emergency System Recovery
If your device becomes inaccessible and the management utility cannot find your device,
please use the following procedure to recover your device over TFTP.
System Recovery Procedures
System recovery is based on the TFTP Client embedded in the device. It can recover the
device from a bad firmware or other unknown reasons that corrupted the firmware image
inside the flash. Follow the procedures below to force AW5500C to download a valid firmware
from the TFTP Server to recover its Operating System.
Default Settings
TFTP Server 10.0.50.201
TFTP Server Subnet Mask 255.255.0.0
Name of firmware Image* firmware.dld
*This firmware image can be obtained from Atop’s website.
 If the device is beeping continuously after power up, the bootloader is damaged and
there is no way to recover it; please contact directly Atop RMA for further solutions.
 Obtain and setup a TFTP server on your PC. Make sure that the PC’s network settings
are set properly according to the default above.
 Rename the firmware image that you obtained from our website to firmware.dld and
place it in the TFTP Server’s root directory. For Solarwinds TFTP Server, it is usually
C:\TFTP-Root.
 Make sure that the device is powered OFF and the Ethernet cable is plugged in.
 Press and hold the reset to default pin under LAN Port then power ON the device. If the
bootloader is still functioning, you will hear one long beep followed by two shorter beeps.
