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)tothe
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)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 EXP710 (5).
5. Connect the OUT port (2) on the left ESM in the second EXP710 (4)tothe
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)tothe
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.
