Perform the following steps to create the recommended cabling scheme shown in
Figure 64:
1. Connect the OUT port (2) on the left ESM in the first EXP100 (3) to the IN
port (1) on the left ESM in the third EXP100 (5).
2. Connect the IN port (1) on the right ESM in the third EXP100 (5)tothe
OUT port (2) on the right ESM in the first EXP100 (3).
3. Connect the IN port (1) on the left ESM in the first EXP100 (3)toport2of
drive channel 1 on the DS4700 Express.
4. Connect port 1 of drive channel 2 on the DS4700 Express to the OUT port (2)
on the right ESM in the third EXP100 (5).
5. Connect the OUT port (2) on the left ESM in the second EXP100 (4)tothe
IN port (1) on the left ESM in the fourth EXP100 (6).
6. Connect the IN port (1) on the right ESM in the fourth EXP100 (6)tothe
OUT port (2) on the right ESM in the second EXP100 (4).
7. Connect the IN port (1) on the left ESM in the second EXP100 (4) to port 1
of drive channel 1 on the DS4700 Express.
8. Connect port 2 of drive channel 2 on the DS4700 Express to the OUT port (2)
on the right ESM in the fourth EXP100 (6).
Figure 65 on page 84 shows the recommended cabling scheme for one DS4700
Express Storage Subsystem and a maximum of six EXP100s behind both ports of a
dual-ported drive channel.
