[Casper] what happens when a logic board is replaced

Tue Dec 16 09:06:52 PST 2008

You can have self maintainer status and get full access to GSX.  I keep
my OS and hardware certs up to date every year so I can do in house
repairs, get warranty reimbursements and of course have full access to
GSX and all of it's tools, like the serial number tool, ASD diagnostics,
etc etc. 

The reason I ask is that we have some machines that have not checked in
our network for a while and we are wondering where they are at.  We do
out source all of our hardware repairs of anything major to a third
party.  There are 5 of us total, and we manage 6,542 Macs now.  No way
any of us have the time to do component level repair on Mac laptops
unless it is like popping a key back on or swapping out RAM. 

I was wondering if a machine came back from repair with new logic board
if it treated it like a new machine.  I do see machines with the same
name in our database as well, and it is represented by the computername
with a (2) at the end of it.

Unless things have changed since I was a service tech, distributing
and/or using the board serializer outside of an Apple Authorized Service
Center violates several Apple agreements (that's not a judgement, just
information)  The service technician should reset the SN when a logic
board is replaced. 

I imagine that in cases, where the MLB was replaced, but the airport
card was not, the JSS has a known MAC to identify the machine with.  If
the MLB and airport are replaced, my guess is that the JSS would treat
it as a new machine.  I believe bluetooth also has a MAC address, but in
most Macs today, BT is part of the same hardware module as airport, so
if airport is replaced, so is BT. 

Again, this is all guesswork until someone asks JAMF.

This is true, but I'm not sure everyone has access to download that tool
from Apple I believe. I'm more annoyed the service company didn't just
DO IT. =) They should, if you have this issue and wanted to go back and
make them.

Apple has a tool you can download called System Board Serializer or
something like that.... You can set your new serial# with it on
new/replaced boards.

I just had my MBP board replaced. It still is recognized as the same
unit computer in the JSS. However, my serial number now equals "System
Serial#".

My wired NIC (en0) is a different Mac address, but my Airport (en1) is
the same. If none of the MAC addresses matched up for some reason then
the JSS is likely to treat it as a whole new system.

I think I recall that the JSS does store more than the two visible MAC
addresses for this particular scenario.

If I recall correctly, the JSS database stores more MAC addresses than
display in the interface.  Perhaps the new MLB's address(es) are being
added to the empty fields?  I assume the repair facility reset the new
MLB's serial number to match your original SN?

This is just a guess based on half-remembered info.  Perhaps a call to
support for a definitive answer?

does it just update the MAC address of the built in ethernet in
Inventory?  Does it create a new entry?
