Top-posting because I am lazy... Since those Junipers are pseudo-chassis-based with pluggable cards, I think you are dying on how the backplane is laid out and detected by OpenBSD.
In the interim, please make sure that dms@ sees the dmesg, principally for the em(4) interface. For what it's worth, I have run OpenBSD successfully on a Cisco 4240 IDS/IPS device, --J >Hello m...@.
