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) to the
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) to port 2 of
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) to the
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) to the
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.
