to 0 (off).
2. Route the main power cords to a power strip or PDU. Ensure the routed cords maintain proper
service clearance.

Cabling the Power Distribution Unit
PDUs can be mounted horizontally below the enclosures at the bottom of the rack. Each PDU AC
cord connects to the appropriate outlet based on the type of cord and power requirements to
supply power to the storage system.
To access the vertically mounted PDUs or servicing area, the PDUs can be lowered out of the rack.
1. Remove the two top mounting screws.
2. Pull down on the PDU to lower.
NOTE: If necessary, loosen the two bottom screws to unhinge the bracket before pulling
down the PDU.
3. Ensure the PDUs are in a fully lowered position before accessing.
