General EVA6400 expansion cabling guidelines

To adapt the cabling used in
Controller A
DP1-A on controller A connects to P1 (I/O-A) on the top disk enclosure in the first loop (expan-
sion rack).
DP2-A on controller A connects to P1 (I/O-A) on the top disk enclosure in the second loop
(expansion rack).
DP1-B on controller A connects to P2 (I/O-B) on the bottom disk enclosure in the first loop (main
rack).
DP2-B on controller A connects to P2 (I/O-B) on the bottom disk enclosure in the second loop
(main rack).
Controller B
DP1-A on controller B connects to P2 (I/O-A) on the bottom disk enclosure in the first loop
(main rack).
DP2-A on controller B connects to P2 (I/O-A) on the bottom disk enclosure in the second loop
(main rack).
DP1-B on controller B connects to P1 (I/O-B) on the top disk enclosure in the first loop (expansion
rack).
DP2-B on controller B connects to P1 (I/O-B) on the top disk enclosure in the second loop (ex-
pansion rack).
Disk enclosures
P1 (I/O-A) on the top disk enclosure in the first loop (main rack) connects to P2 (I/O-A) on the
bottom disk enclosure in the first loop (expansion rack).
P1 (I/O-A) on the top disk enclosure in the second loop (main rack) connects to P2 (I/O-A) on
the bottom disk enclosure in the second loop (expansion rack).
P1 (I/O-B) on the top disk enclosure in the first loop (main rack) connects to P2 (I/O-B) on the
bottom disk enclosure in the first loop (expansion rack).
P1 (I/O-B) on the top disk enclosure in the second loop (main rack) connects to P2 (I/O-B) on
the bottom disk enclosure in the second loop (expansion rack).

Connecting an EVA8400 multi-product rack to a 0C6D expansion rack

For reference,
multi-product rack example assumes that there is non-EVA hardware in the rack above the controllers.
