Step 5 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.

To establish power redundancy for the storage system, route each power supply to independent PDUs and route the PDUs to separate external power sources on different branch circuits.

Procedure

1. Confirm that the PDU breakers are turned off.
2. Insert the power cable plug completely into the receptacle on each power supply.
3. Fix the power cable holder to the power cables.
4. For the drive box, correct the twisted power cable and fix it to the rail with omega clips.
5. Insert the power cable plug for power supply 1 into the PDU, and insert the power cable for power supply 2 into the opposite side of the rack to provide redundant power for the storage system.
   Connect from J101 to J103 and from J201 to J203 sequentially. Confirm that the power cable is firmly fixed to the rack with the PDU cable clamp or repeat binders. Tap on the image to see it in fullscreen.
   
   
6. Route the power cables.
   1. Route the PDU power cables through the cable passing opening at the bottom of the rack.
   2. Remove the cable holders from the rack frame by removing the hex socket head bolts.
   3. Fasten the power cables to the rack frame by attaching the cable holders with the Allen bolts.
   4. Check that the connecters are securely fixed after the assembly work. Tap on the image to see it in fullscreen.

7. After routing the power cables, push the power cable plugs into the PDU again. They might have been loosened during cable routing.
8. Turn on all breakers of the PDUs.
