Perform the following steps to create the recommended cabling scheme shown in
Figure 73:
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)toport2of
drive channel 1 on the DS4700 Express.
4. Connect port 1 of drive channel 2 on the DS4700 Express to port 1B (1)on
the right ESM in the third EXP810 (4).
5. Connect port 1B (1) on the left ESM in the second EXP810 (3)toport1of
drive channel 1 on the DS4700 Express.
6. Connect port 1B (1) on the right ESM in the second EXP810 (3)toport2of
drive channel 2 on the DS4700 Express.
Figure 74 on page 92 shows the recommended cabling scheme for one DS4700
Express Storage Subsystem and four EXP810 storage expansion enclosures
behind both ports of a dual-ported drive channel.
