1. Make all connections from the left ESMs to the right ESMs in the expansion
enclosures, as indicated by 21, 23, 22, and 24.
2. To create drive channel 1, after connecting enclosures 1, 2, 3, and 4 together
(21), connect drive port 4 of controller A (4A) to EXP710 enclosures 1 (5),
2 (6), 3 (7), and 4 (8); then, connect drive port 1 of controller B (1B) to
enclosures 4 (8), 3 (7), 2 (6), and 1 (5).
3. To create drive channel 3, after connecting enclosures 5, 6, 7, and 8 together
(23), connect drive port 3 of controller A (3A) to enclosures 5 (9), 6 (10),
7 (11), and 8 (12); then, connect port 2 of controller B (2B) to enclosures
8 (12), 7 (11), 6 (10), and 5 (9).
4. To create drive channel 2, after connecting enclosures 9, 10, 11, and 12
together (22), connect drive port 2 of controller A (2A) to enclosures 9
(13), 10 (14), 11 (15), and 12 (16); then, connect drive port 3 of
controller B (3B) to enclosures 12 (16), 11 (15), 10 (14), and 9 (13).
5. To create drive channel 4, after connecting enclosures 13 (17), 14 (18), 15
(19), and 16 (20) together (24), connect drive port 1 of controller A (1A)
