To connect controllers A and B to one EXP3500 storage enclosure that has two
ESMs, complete the following steps:
1. Connect the EXP3500 storage enclosure to controller A:
a. Connect one end of a SAS cable to controller A.
b. Connect the other end of the SAS cable to one of the In (↑) SAS connectors
on the left ESM in the EXP3500 storage enclosure.
2. Connect the EXP3500 storage enclosure to controller B:
a. Connect one end of a SAS cable to controller B.
b. Connect the other end of the SAS cable to one of the In (↑) SAS connectors
on the right ESM in the EXP3500 storage enclosure.

The DS3500 controllers support more than one EXP3500 storage enclosure per
physical port, so multiple EXP3500 storage enclosures can be connected by
chaining them together.
To connect DS3500 controllers A and B to multiple EXP3500 storage enclosures that
have two ESMs each, complete the following steps:
1. Connect one EXP3500 storage enclosure to controller A:
