Product Description

Release 7.5.1 and above is required to support the IMACS 8000 shelf. All supported
capabilities existing in the 7.x.y series is available and supported in the 8000 shelf, with the
exception of being able to load some of the older user cards. These older user cards have not
had a software update since 2005, and the likelihood of needing to upgrade one is remote.
Release 7.x.y has made hardware changes to the CPU and Interface cards with the intent of
providing a low-impact switching time when going between processors. This time is targeted
to be less than 250 micro seconds, and is supported for several card types.
1.1.1

CPU Card Support

Host code 7.x.y operates on the CPU card and requires 8000-CPU-60751 or higher Host
Firmware. No other CPU Cards are supported.
