Perform the following steps to create the recommended cabling scheme shown in
Figure 75:
1. Connect port 1A on the left ESM in the first EXP810 ( 2 ) to port 1B ( 1 ) on
the left ESM in the third EXP810 ( 4 ).
2. Connect port 1A on the right ESM in the third EXP810 ( 4 ) to port 1B ( 1 ) on
the right ESM in the first EXP810 ( 2 ).
3. Connect port 1B ( 1 ) on the left ESM in the first EXP810 ( 2 ) to port 2 of
drive channel 1 on the DS4700 Express.
4. Connect port 1A on the left ESM in the third EXP810 ( 4 ) to port 1B ( 1 ) on
the left ESM in the fifth EXP810 ( 6 ).
5. Connect port 1A on the right ESM in the fifth EXP810 ( 6 ) to port 1B ( 1 ) on
the right ESM in the third EXP810 ( 4 ).
6. Connect port 1 of drive channel 2 on the DS4700 Express to port 1B ( 1 ) on
the right ESM in the fifth EXP810 ( 6 ).
