Perform the following steps to create the recommended cabling scheme shown in
Figure 69:
1. Connect the OUT port (
2
) on the left ESM in the first EXP710 (
3
) to the IN
port (
1
) on the left ESM in the third EXP710 (
5
).
2. Connect the IN port (
1
) on the right ESM in the third EXP710 (
5
) to the
OUT port (
2
) on the right ESM in the first EXP710 (
3
).
3. Connect the IN port (
1
) on the left ESM in the first EXP710 (
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 EXP710 (
5
).
5. Connect the OUT port (
2
) on the left ESM in the second EXP710 (
4
) to the
IN port (
1
) on the left ESM in the fourth EXP710 (
6
).
6. Connect the IN port (
1
) on the right ESM in the fourth EXP710 (
6
) to the
OUT port (
2
) on the right ESM in the second EXP710 (
4
).
7. Connect the IN port (
1
) on the left ESM in the second EXP710 (
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 EXP710 (
6
).
Figure 70 on page 88 shows the recommended cabling scheme for one DS4700
Express Storage Subsystem and a maximum of six EXP710 storage expansion
enclosures behind both ports of a dual-ported drive channel.
