RACK PDU AP7953

[Anonymous user]

Hello,

I bought three RACK PDU AP7953 from eBay. One work fine, but the two others have zeroed MAC, empty Serial Number, model and so on. It's obvious, that the Flash was cleared. I have read that in such cases you recommend to change the network card. But I want to try to recover the Flash content by myself. I searched a lot on the Internet and found that there is a service mode in which the contents of the memory can be read and adjusted. But the login i found works only on old firmware, prior aos version 2.0. My cards are with newer versions and entering in service mode is different, but I do not know it.

Could you tell me how to get into the service mode or send me the old firmware?  

Thank You.
