trying to find information on mvme5100 battery

[Maren Purves via Tech-talk <tech-talk@aps.anl.gov>]

Hi all,

I'm working on some monitoring stuff for a new receiver
and as the new receiver isn't here yet I just got a spare
mvme5100 board. Trying to boot it I found that it had
'forgotten' its boot parameters. It is supposed to have
a replaceable battery and we found on part that looks like
it may be a battery but with no part number or anything on
it.
None of the manuals I found on-line has a board layout
with labels on it that would tell me where the battery
is (assuming that the battery is the problem), or had
any specifications for it.
Pulling out another spare board, it behaved the same way.
If we have to put any of these spare boards into use that
would mean that they would have to have their boot parameters
reinstalled each time we have a power glitch. That's OK
for us here in the office/lab but not OK for people
operating telescopes at night.

Does anybody know and can either point me somewhere where
to find this information - or have the information and
pass it on?

Thanks in advance,
