Emergency System Recovery

 

If the device becomes inaccessible and the management utility cannot find the device, please use the following 

procedure to recover the

 

devices over Trivial File Transfer Protocol 

(

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 corrupting the firmware image inside the flash memory

. 

Please follow the procedures 

below to force SW550XC to download a valid firmware from the TFTP Server to recover its operating system

This firmware image can be obtained from Atop

’

s website

.

 

 

 

If the device is beeping continuously after power up, this means that the bootloader is damaged and there is 

no way to recover it

. 

Please contact Atop directly to obtain RMA number

 

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 setting in the above table

. 

 

 

Rename the firmware image that you obtained from our website to 

“

”

 and place it in the TFTP 

Server

’

s root directory

. 

For Solarwinds TFTP Server, it is usually C

will hear one long beep followed by two shorter beeps

. 

 

 

Release the reset pin after hearing seven consecutive short beeps

. 

Then, the

 

device will automatically request 

files from TFTP Server

. 

Please wait until the device shows up on the management utility

. 

This process could 

take up to five minutes or even more

.
