Words 12 through 15, bits 0 to 7 - indicate the device fault status for
logical racks 0, 1, 2, 3, 8, 9, 10, and 11. Bits 0 through 3 are for
primary/normal devices and bits 4 through 7 are for complementary
devices. Each bit corresponds to a quarter logical rack location. If a
device is not responding to communications, has gone offline, or is
configured to an incorrect logical rack size, all bits corresponding to
the device are set to 1. This is highlighted in the example below.
