Hi all,
I just discussed the following with my SE:
I wanted to get new 64Bit REs with some new gear,
but run the 32-Bit JunOS on them - he denied that
this is possible.
I tried to research that, but have not yet found
something in the docs - does anybody here have some clue
about that?
As the REs are 'only' standard PCs, I do not see any reason
for them to be not capable of running 'legacy' 32Bit JunOS.
I would be really glad if someone has some clue about that and
could unearth the truth.
We are in the same situation, and have received the same -disappointing-
answer from our SE.
I've just given this a quick try on a MX running 10.4S1.1 (64bit) with
RE-S-1800X4-16G, and it seems it is not possible to get 32bit JunOS
installed using a jinstall image.

Interestingly, on T640/T1600 32bit JunOS _is_ supported on
a 64bit RE-DUO-C1800-8G.
These REs will also support 64bit JunOS in the future.
Both REs types use Intel Xeon CPUs.
So I would assume the limitation on MX is non-technical.
RE-DUO-C1800-8G has
CPU: Intel(R) Xeon(R) CPU L5215 @ 1.86GHz (1862.01-MHz 686-class CPU)
RE-S-1800X4-16G has
CPU: Intel(R) Xeon(R) CPU C5518 @ 1.73GHz (1729.11-MHz K8-class CPU)
cheers,
-jr
