To make the loop 1 connections between the main rack and the expansion rack:
1. Unplug DP1-A on controller A from P1 (I/O-A) on disk enclosure 1 (S-1) and:
a. Connect DP1-A on controller A to P1 (I/O-A) on disk enclosure 27 (S-27).
b. Connect P1 (I/O-A) on disk enclosure 1 (S-1) to P2 (I/O-A) on disk enclosure 25 (S-25).
2. Complete the following verification steps:
a. Verify that the I/O modules on the added disk enclosure has been assigned an index
number of the next higher enclosure number.

array hardware in the Navigation pane and the I/O module displays a good operational
status.
3. Unplug DP1-B on controller B from P1 (I/O-B) on disk enclosure 1 (S-1) and:
a. Connect DP1-B on controller B to P1 (I/O-B) on disk enclosure 27 (S-27).
b. Connect P1 (I/O-B) on disk enclosure 1 (S-1) to P2 (I/O-B) on disk enclosure 25 (S-25).
