Cabling PowerVault MD1200 Series Expansion Enclosures
You can expand the capacity of your PowerVault MD3400 and MD3420 storage array by adding
PowerVault MD1200 series expansion enclosures. You can expand the physical disk pool to a maximum
of 120 slots (or 192, if enabled using Premium Feature activation) using a maximum of seven expansion
enclosures.
To connect an MD1200 series expansion enclosure to your MD3400 series array:
1. Connect the supported SAS cable (MiniSAS HD end) to the SAS OUT Port 0 on the MD3400 series
storage array.
2. Connect the other end of the SAS cable to the IN port on one of the MD1200 series Enclosure
Management Modules (EMM).
3. To add more MD1200 expansion enclosures, daisy chain them to the first expansion enclosure.
