Figure 52. Connecting two EXP810 storage expansion enclosures into redundant drive loop
B
If you want to connect more storage expansion enclosures into drive loops A
and B, continue with Step 3; otherwise, go to "Connecting the redundant
EXP810 drive loop to the DS4300" on page 69.
3. Connect additional storage expansion enclosures to drive loops A and B, as
shown in Figure 53 on page 69.
Starting with the second storage expansion enclosure, connect each additional
storage expansion enclosure into drive loops A and B in the same manner.
Leave port 1A on the ESM B of the last (fourth) storage expansion enclosure in
the loop and port 1A on the ESM A of the first storage expansion enclosure
unoccupied.
