There are up to four host minihubs, two per controller (Figure 2-14). Minihubs 1 and 3
correspond to the top controller (controller A) and minihubs 2 and 4 correspond to the
bottom controller (controller B). Each minihub provides host loop capability and
self-diagnostic features. To ensure redundancy, you must connect each host to each
controller board.
