ALOM upgrade problem
In our environment, we were upgrading a Sun Fire V240 system's ALOM to >= 1.6 to enable network management via ssh. However, we could not install the latest version of ALOM--v1.6.6 as of this writing--as the system's OBP is too old.
ALOM v1.6.6 requires a minimum OBP of 4.11.4. However, we couldn't upgrade OBP as OBP 4.11.4 or later requires ALOM v1.2.

Fortunately, we located ALOM v1.3 on one of our network volumes; Sun does not allow downloading previous versions of ALOM. We were able to upgrade ALOM v1.0.0 ALOM v1.3.0. We can now upgrade OBP, and then upgrade to the latest ALOM.
