Are you sure about this address ?  It's should start with 08-00-2b...
and what makes you this is the "bogus" address ?

The error ?54 means there is no supporting host answering the printer's 
boot request.  It is not the hardware problem.  You need to check the
supporting host configuration.  If you change the controller board, you 
need to continue use old board's Ethernet address ROM or change the
supporting host's boot configuration.

Providing your information, you got very poor tech suppport suggestion.
If they understand the ?54, the first suggestion is to check the supporting
host or network configuration, not to swap the hardware parts.

    I'm sure they're getting an e-net adrs of 12-34-56-78-9A-BC, on post.
    This is due to some kind of hardware problem, and causing the ?54
    fault. Somebody told me they've seen this before if the e-net chip on
    the controller is put in backwards, but then the chips smokes/pops.
    
    They've got another LPS32, next to the inoperable one, set up the same
    way, and working fine. The ?54 error is due to the bad e-net adrs the
    LPS32 is sending to the host. A new controller w/ a new e-net chip that
    was sent to them didn't fix the problem, so I don't think tech
    support's suggestion of trying the backplane/motherboard was a bad
    idea. 
    
    Also, you answered you're own question: - the e-net adrs should start
    w/ 08-00-2B, that's why 12-34-56-78-9A-BC is a bad one, and a hardware
    problem.
    
    anybody wanna fly to Switzerland? 

    you say there's another lps32 next to this one, as a troubleshooting 
    method you might putting the bad controller, e-net chip included into
    the good printer.  Of course there is always a danger in that, something 
    might be blowing something.  But if your at the end of your rope, this 
    would tell you if it's in the print engine, the controller or the software.
    
    If the bad controller and address come up in the good printer, you 
    will know both the controller, chip and software are good. 
    It would have to be in the e-net cabling or the printer. If they 
    don't come up, there's a chance the bad printer is blowing boards.
    Trying the good printers controller with enet chip in the bad printer
    may be a bit more dangerous, you probably don't want to try that. 
    
    Try another test would be to put a loopback connector on the bad 
    printer to see if it then displays the correct address, if not, the
    problem is in the printer, it it does there's something wrong with the 
    net connection (either way you'll still get ?54 but you can read the 
    address to see if it's corrected)

    I'm sorry I didn't mention that I instructed the VAR on how to run
    the FTM LANCE 1,4,6 test w/ the DESTA terminated. He relayed the
    instructions to his customer in Switzerland, and was told that after
    the test was run, it came back w/ the same 12-34-56-78-9A-CB  & ?54.
    
    Unfortunately I can only go on what the VAR is told by his customer in
    Switzerland. ??? I suggested he just have the bad LPS32 returned.
    
    -I thought maybe somebody had seen this problem before-thanks for the
    assistance

    FWIW: This problem of the bad e-net adrs. of 12-34-56-78-9A-BC was due
    to a bad printserver memory option bd.  P/N:  54-23796-02  ???
    
    Apparently the h.w. e-net adrs. gets loaded into a certain area of this
    memory, and it wasn't! I couldn't find any info about this part though,
    looking in STARS or QRL ??? Found nothing !?!!?!?!
    
    Feel free to comment.

    If your stockroom doesn't stock 54-23796-02 (memory bd option with
    handle) try 54-23796-01 (memory bd option without handle), I thought
    the -01 was the part they were going to stock.
    
    This memory option makes the lps32 into an lps32+.  Customers can order
    a plus or upgrade their existing lps32 (or lps20 turbo) with lps3x-ua.
    It is customer installable.  For more info try looking in TIMA for
    EK-TP232-IN, this is the only guide I know of that covers this option.
    (Turbo Printserver 20 and PrintServer 32 Printers Memory Installation
    Instructions).
