1. Using the cabling diagram, connect each drive box to the controller using either iSCSI or fibre channel cables
depending on the connectors on the controller.

Step 6: Connect the storage system to power
Power for the storage system is provided through two power supplies, one per controller. The input voltage is auto-
adjusting for 200-240 (-11%) VAC, 50-60 Hz power connections.
For best practice, establish power redundancy by routing each power supply to independent PDUs and then routing the
PDUs to separate external power sources on different branch circuits. This arrangement enables the storage system to
continue operating if AC power is lost to one power supply.
NoteMultiple outlets in a PDU or power strip do not constitute an independent electrical source.
Procedure
1. Confirm that all power sources are off.
2. Connect an AC power cable to the power receptacle on the rear of each controller.
3. Route the power cables from each controller to separate PDUs, and then use the pre-installed tie wraps at each
controller power receptacle to secure the power cables.
4. Connect the PDUs to separate external power sources on different branch circuits.
NoteTo prevent the storage system from being turned off by accident, make sure the external power sources are
not controlled by a wall switch.
