Perform the following steps to create the recommended cabling scheme shown in
Figure 72:
1. Connect port 2 of drive channel 1 on the DS4700 Express to port 1B (1)on
the left ESM in the first EXP810 (2).
2. Connect port 1B (1) on the right ESM in the first EXP810 (2)toport1of
drive channel 2 on the DS4700 Express.
3. Connect port 1 of drive channel 1 on the DS4700 Express to port 1B (1)on
the left ESM in the second EXP810 (3).
4. Connect port 1B (1) on the right ESM in the second EXP810 (3)toport2of
drive channel 2 on the DS4700 Express.
One DS4700 Express and three or more EXP810 storage
expansion enclosures
To connect three or more storage expansion enclosures to a DS4700 Express
Storage Subsystem, alternately connect a storage expansion enclosure to one of
the drive ports of the dual-ported drive channel then connect to the other port until
all of the storage expansion enclosures are attached. Figure 73 on page 91 shows
the cabling scheme for one DS4700 Express Storage Subsystem and three
EXP810 storage expansion enclosures behind both ports of a dual-ported drive
channel.
