Component Description
Power supplies
The Verde enterprise expansion node includes two power supplies to provide
N+1 redundancy and fail ‐ over protection.

Each power supply has its own AC power connector.

Each power supply has a single LED that lights to indicate when the power is
on and functioning normally.
SAS connectors The rear panel of the Verde enterprise expansion node has four SAS ports used
to connect an expansion node to a master node. Two ports are for primary
connections and two ports are for secondary connections. Labels next to each
port identify if the port is a primary or secondary connection. For information
on how to connect cables between the master node and enterprise expansion
node, see the Spectra Verde Array Installation Guide .
Data drives Up to 21 data drives can be installed in the rear of the expansion node.
Empty drive sleds
When fewer than the maximum number of drives are installed, empty drive
sleds are installed in the unused drive bays to prevent contaminants from
entering the enclosure and to maintain proper air flow.
