2. Connect the first two drive enclosures to drive Loop B (Figure 8-1).
Starting with the first drive enclosure, connect an interface cable from the In
connector on the right environmental status module to the Out connector on the
right environmental status module in the second (next) drive enclosure. If you want
to cable more drive enclosures into Loops A and B, continue at step 3, otherwise,
skip to step 4.
3. Connect additional drive enclosures to drive Loops A and B (Figure 8-2).
Starting with the second drive enclosure, cable each additional drive enclosure into
Loops A and B in the same manner. Leave the In connectors on the last drive
enclosure (the one farthest from the host) and the Out connectors on the first drive
enclosure unoccupied. When finished, continue at step 4.
