Cabling the EXP3500 storage enclosure
The EXP3500 storage enclosure comes with one ESM, which enables you to connect the EXP3500 storage
enclosure to a DS3500 storage subsystem. If you are attaching the EXP3500 to a dual controller DS3500
storage subsystem, you must add a second ESM to the EXP3500 storage enclosure to provide a redundant
drive path.
