Media error while reloading Licensed Internal Code

Any help would be greatly appreciated.

 

The Model 500 V4R5 was running fine before this was started and it is not a
production box so we can anything we need to, to get it up and running.

 

It was decided to replace the Licensed Internal Code using PWRDWNSYS
OPTION(*IMMED)  RESTART(*YES)  IPLSRC(D)  

Everything was running fine, took the first CD (Licensed Internal Code)
asked for Next CD (OS400), loaded it and it, and it ran for awhile

Then we got "Media Error"  only option on the console was option to end so
we ended it.

 

Now we have SRC900 3121 and we cannot use the front panel to select the IPL
Source (only displays option 1 and option 4)

The white power button does not do anything, as last chance effort we loaded
the Licensed Internal Code and unplugged the machine. After it powered down
we plug it back in 

and it runs for a bit then we get the same SRC Code B900 3121

I have searched the archives and the IBM site for this SRC code without any
luck.

All we want to do at this point is restart the reload of the licensed
internal code and OS400

There is nothing on the machine we need.

 

Any suggestions on getting this restarted?
